Introduction

Thank you for your purchase of the AtlasIED CLA Series amplifier. The CLA Series is a high-power amplifier designed for versatility, suitable for both commercial 25V/70V/100V distributed systems and professional applications requiring amplification for low impedance loads like 4Ω or 8Ω. Notably compact and lightweight compared to similar-performing models, the CLA Series incorporates Class D Output topology, offering the efficiency of a Class AB amplifier without compromising on sound quality.
The amplifier’s power supply adopts a switch-mode, global auto-sensing design, ensuring a stable output even in fluctuating power conditions. The power supply and output stage are meticulously engineered to deliver exceptional dynamic high output voltage and current to virtually any loudspeaker load.
Key features of the CLA Series include rear panel detented level controls, remote level control, GPI control for standby low energy mode, priority mute, and balanced inputs. The amplifiers also boast a unique output stage with a low-resistance, direct-coupled thermal transfer design, effectively maintaining optimal temperature across all loads and output levels. Additionally, the CLA Series amplifiers are energy-efficient, meeting Energy Star standards and drawing only 1W of power in standby mode.
Whether your application involves a large distributed constant voltage sound system or a high SPL sound reinforcement system, the AtlasIED CLA Series stands as the solution for high-power and cost-effective amplification needs.
AtlasIED Amplifier Power Share Description
The AtlasIED Power Share feature is applicable to amplifiers with two channels of amplification, including 2 CH and 4 CH amplifiers, albeit controlled in pairs. Power Share enables the user to allocate a specified amount of audio amplified power to each  channel. This allows for a deliberate imbalance where one amplifier channel can have more power than the other. Importantly, Power Share does not require any external devices like phones, tablets, or computers for configuration, nor does it rely on APP control software. The control for channel power is facilitated by a switch conveniently located on the amplifier.
In contrast to traditional amplifier designs where the power supply’s maximum delivery is determined by the amplifier model’s power rating, amplifiers with multiple channels that share a common power supply typically have fixed channel amplifier ratings. For example, a two-channel amp producing 200W per channel necessitates a 400W power supply. However, with AtlasIED Power Share technology, a 400W power supply can be configured using a switch. When selected, this switch configures the amplifier to allocate 350W of power to Channel 1 and 50W to Channel 2. The combined power of both channels still totals the maximum 400W from the power supply. Furthermore, individual channels can still be configured to deliver 200W each if desired.

Front Panel

1. Ventilation / Cooling
   The CLA amplifiers are equipped with fan-assist cooling, which functions by drawing cool air in from the front of the amp and expelling hot air through the rear and side panels. The cooling system of the CLA Series includes an idle mode with convection cooling and variable-speed fan assist cooling during amplification. Notably, the design of the CLA Series is such that air filters are not necessary. However, in environments with high levels of dust or dirt, occasional cleaning may be required to ensure optimal performance.

2. AC Mains & Power Supply Status Indicator
   The CLA Power Supply Status indicator utilizes RGB LED technology to provide a visual indication of various conditions related to the incoming AC mains and the amplifier’s power supply:
   A. Idle Mode (Blue Blinking) – The LED will blink blue indicating the amplifier is in a low power state. The fans ore off during this state with the amplifier operating in convection cooling mode. The amplifier is ready to receive a signal and has no wake up delay
   B. Power On Mode (Blue Steady) – The LED will illuminate a steady blue state when proper AC mains power is applied to the amplifier, indicating that the amplifier is active and ready for use.
   C. Standby Mode (Yellow Steady) – A steady yellow state indicates Standby mode, where the amplifier’s power supply is in Energy Save Mode, and the amplifier is not ready for use. To activate Standby mode, the rear panel remote activation control GPI must be triggered by shorting the (STB) and ground (G) pins together. In Standby mode, the CLA power consumption is less than 1 watt, and the amplifier will not pass audio.
   D. Protect Mode (Red Steady) – The LED will be steady red in the event of a fault condition with the power supply. If this occurs, unplug the amplifier from the AC mains and have the AC mains inspected by a qualified technician. If the AC power is stable, plug the CLA amplifier back in. If the LED remains red, contact AtlasIED Tech Support.
   E. AC Fault (Red Blinking) – The LED will blink red when there is low or high AC mains voltage, indicating a fault condition with the AC mains powering the amplifier. Under this condition, the amplifier will not function until the AC mains are within the amplifier’s voltage requirements. CLA AC Mains operating voltage requirements are 100V – 132V and 208V – 240V.
   Note: If one of the speaker outputs has a short, the amplifier will go into protect mode with all Channel LED’s and the AC main LED blinking Red. The amplifier will try to reset itself every 20 seconds until the short has been removed.
   F. Thermal Protection (Yellow Blinking) – This LED represents the temperature condition of the amplifier. It will blink yellow if the power supply’s thermal protection is triggered, causing the power output to reduce. This allows the amplifier to cool down while still remaining functional.

3. Channel Status Indicators
   The CLA Channel Status indicator employs RGB LED technology to offer a visual indication of various conditions related to the channel’s operation. Each channel has a separate indicator:
   A. Clear (Off) – The LED will not illuminate, indicating that the amplifier channel is stable and ready for use.
   B. Green (Blinking) – The LED will blink green when 25mV if input signal is applied to the amplifier.
   C. Yellow (Blinking) – The LED will blink yellow when the maximum amplifier output level is achieved.
   D. Red (Blinking) – The LED will blink red when the amp channel exceeds the maximum current settings, indicating a wrong load selection. Confirm that the load applied to the amp channel and the load switch selection match.
   Note: If one of the speaker outputs has a short, the amplifier will go into protect mode with all Channel LED’s and the AC main LED blinking Red. The amplifier will try to reset itself every 20 seconds until the short has been removed.
   E. Red (Steady) – The LED will be steady red when the amp channel is in protect mode. Remove the speaker load from the amp channel, and if the LED turns off, look for a short in the speaker line. If the LED continues to illuminate and the speaker load is removed from the amp channel, contact AtlasIED Tech Support.
   F. Yellow (Steady) – The LED will be steady yellow when the channel is in a thermal protect condition. Once the thermal condition is resolved, the yellow LED turns off.

Rear Panel

1. AC Mains Input
   The CLA Series is equipped with a global, wide-range AC Mains power supply that functions on 100V-120V and 220V-240V 50/60Hz power sources.
   The amplifiers feature an IEC-600320-C14 receptacle and come with a detachable 1.8-meter 14-gauge NEMA 5-15 power cord. Insert the IEC connector of the power cord into the IEC receptacle of the CLA Series amplifier, ensuring it is securely connected. For non-North American applications, refer to local electrical code requirements to select the appropriate power cord.

2. Balance Input
   Connect balanced line level signals to the (+) (–) and (G) terminals. Note: If connecting an unbalanced line level input, short the (G) and (–) terminals together.

3. Channel Level Controls
   Each channel of the CLA amplifier features an independent detented level control. When either potentiometer is turned down (left or fully counterclockwise), no signal will come out of the corresponding amp channel. When turned up (right or fully clockwise), the amp will be set for maximum level.
   A. Low Audio Level Applications – If the audio levels are producing only a few watts, we recommend setting the level controls around the 12 o’clock position and increase the input signal to optimize the system’s gain structure and reduce the noise floor. For 70V and 100V applications at any power level, it is recommended to set the level controls at the 3 o’clock position and increase the input signal to optimize the noise floor gain structure.
   B. CLA & Atmosphere Gain Structure – Mating the CLA amplifier with an Atmosphere AZM4 or AZM8 audio processor is an excellent match. The AZM units are designed with commercial-grade zone output stages. When starting to configure the system, and to achieve a good balance with the gain structure, we recommend setting the CLA level controls around the 12 o’clock position.

4. GPI Control Port
   The CLA GPI control port serves two functions:
   A. Standby Mode – Connect Pin 1 (STB) to Pin 3 (G) via a switch to activate Standby mode, muting all channels and placing the amplifier in Energy Save mode. When Standby is activated, the AC Mains Power LED illuminates a steady Yellow state, and power consumption is less than 1W. Switch requirements are low voltage and current SPST.
   B. Priority Mode – Connect Pin 2 (PRI) to Pin 3 (G) via switch to activate Priority mode, muting all inputs. Switch requirements are low voltage and current SPST. All Channel LED’s will blink Red.

5. Remote Level Control Port
   To enable remote control of the level on the CLA Series, you can use the Remote Level Control port. This control port operates on a 10KΩ based system, and it is recommended to use the optional AtlasIED WPD-VC10K wall control for this purpose. Follow these guidelines for proper setup:
   A. Recommended Control – It is recommended to use the optional AtlasIED WPD- VC10K wall control.
   B. System Configuration – Set the system’s maximum levels using the amplifier level controls. Then, utilize the remote 10KΩ linear potentiometer as an attenuator.
   C. Wiring Requirements – Wiring the WPD-VC10K will require three-conductor unshielded wire, connecting the WPD terminals to the amplifier.
   D. Maximum Distance – The maximum distance for wiring can be up to 500 feet.
   E. Individual or Combined Control – Note that each channel of the CLA amplifier can be controlled individually or combined. Connect the “G” pin to the Low Z side of the pot and the 10V to the Hi Z side of the pot.
   F. Wiring Details – The wiper (P3 Below) of the pot should connect to the channel return pins labeled 1, 2, 3, or 4. When 10VDC is applied to the channel return pin, the amplifier will be at full power. Note: If the level control is not operating in the following manner with the level control is to the right (Fully Clockwise) the amplifier output is at maximum and with the level control is the left (Fully Counterclockwise) the +10V and the G are reversed.
   Please ensure that the wiring is done using proper techniques and adhere to safety guidelines. If in doubt, consult the user manual or contact AtlasIED support for further assistance.

6. Loudspeaker Connections
   The CLA Series amplifiers are equipped with a locking Euro Block type connector. Please follow these guidelines when working with the connector, keeping safety in mind:
   A. Safety Precautions – Before starting the process, ensure that the amplifier is unplugged from the AC mains source to avoid potential high voltage electrical shock.
   B. Connector Details – The removable Euroblock connector is a 2-position, 5.08mm pitch design and is connected to the chassis by the 2 incorporated screws.
   C. Wire Gauge Recommendation – It is recommended to use 14-gauge wire or larger for connecting to the loudspeaker.
   D. Wire Size Acceptance – The terminals can accept wire sizes of 18-gauge to 12-gauge Class 3 wiring.
   E. Wire Preparation – Properly prepare the wire by stripping it back 0.250″ (5mm). We do not recommend tinning (soldering the wire).
   F. Connection Process – Insert the wire into the terminal block slot and secure it by tightening the screws firmly. This step is critical to ensuring a secure connection for both safety and optimal audio quality.
   G. Caution – Failure to tighten the screws securely could lead to electrical shock or damage to the amplifier.
   Always follow safety guidelines and manufacturer recommendations when working with audio equipment. If you have any doubts or concerns, consult the user manual or contact the manufacturer’s support for clarification and assistance.

7. Amplifier Load Configuration Switches – IMPORTANT!
   The CLA Amp series provides flexibility in configuring load requirements, allowing independent load selections for each channel. Each channel can be configured for 2Ω, 4Ω, 8Ω, 25V, 70V, and 100V loads. Two Dip Switches dedicated to each specific channel are used for configuring the amplifier channels’ load selections.
   Important   Note: Failure to choose the proper setting for the load applied may cause the amplifier to go into protect mode.
   Dip Switch Configuration:
   • DIP SWITCH #1 & #2: Channel 1 Load Selection
   • DIP SWITCH #3 & #4: Channel 2 Load Selection
   Channel 1 Load Selection Switch Positions:
   • 100V: DP SW #1 UP & #2 UP
   • 70V: DP SW #1 UP & #2 DOWN
   • 8Ω: DP SW #1 DOWN & #2 DOWN
   • 4Ω: DP SW #1 DOWN & #2 UP
   Note: For 2Ω loads or 25V systems, use 4Ω switch settings. Refer to the power specifications for power ratings corresponding to the selected load.
   By following the provided chart and ensuring the correct Dip Switch positions, you can tailor the amplifier’s load configuration to suit your specific needs. Always refer to the user manual for additional details and specifications.

8. Power Share Selections
   The Power Share rotary switch in the CLA Amp series allows you to direct the amplifier’s power between two channels. The number of Power Share rotary switches depends on the amplifier model: CLA402 / CLA202 2-channel amps have one Power Share switch, while CLA804 / CLA404 4-channel amps have two Power Share switches.
   A. Power Supply and Channels – For every two amplifier channels, there is one dedicated power supply, each with a maximum power delivery in watts.
   B. Power Share Operations – Power Share enables you to direct the power between channels by selecting the power level using the Power Share rotary switch.
   C. Switch Indication – The Power Share switch has a double arrow indicator to show the power selection between the two channels.
   D. Example – CLA402 – The CLA402, being a two-channel amp, has a single 400W power supply shared between CH 1 & CH 2. If the Power Share switch is set at 200W for CH 1 and 200W for CH 2, each channel receives an equal 200W. Rotating the switch one click to the right may result in CH 2 getting 350W and CH 1 receiving 50W, while the total power between both channels remains 400W. Importantly, the load selection does not affect the Power Share selection.
   Always refer to the user manual for detailed instructions on using the Power Share feature specific to your amplifier model. The double arrow indicator and clear labeling on the switch assist in visualizing the power distribution between channels.
   E. Power Share Selection Examples

Placement of the Amp

Turn off all equipment before making connections. Install the amplifier in a standard-width 19″ rack. It can be mounted above or below anything that does not generate excessive heat. Although the unit’s chassis is shielded against radio frequency and electromagnetic interference, extremely high fields of RF and EMI should be avoided.
Ventilation – The appliance should be situated so that its location or position does not interfere with proper ventilation. For example, the CLA amplifier should not be situated in a sealed cabinet or on a shelf with obstacles on it that may impede the flow of air through the ventilation openings. It is recommended that it be rack mounted into an equipment rack.
H e at – The CLA amplifier should be situated away from heat sources such as radiators, heat registers, stoves, or other appliances (including amplifiers) that produce excessive heat. Ambient temperatures should not exceed 95° F (35°C) when equipment is in use.
Cabling
The CLA amplifier can be used with either balanced or unbalanced sources, and the outputs can be used with either balanced or unbalanced loads, provided the proper cabling is used. A balanced line is defined as a two-conductor shielded cable with the two center conductors carrying the same signal but of opposite polarity when referenced to ground.
An unbalanced line is generally a single-conductor shielded cable with the center conductor carrying the signal and the shield at ground potential.
Balanced Input – AtlasIED recommends using either 20-gauge or 22-gauge two-conductor wire with shield for low level signals. Maintain the proper polarity, (+) to (+), (–) to (–), and shield to ground. Note: The ground center pin of the Phoenix connector is common for both channels.
Loudspeaker Outputs – Use Class 2, 2 conductor unshielded wire of the appropriate gauge. Contact AtlasIED technical support at 1-800-876-3333 with questions regarding wire gauge. The number of loudspeakers connected, and their tap settings will be required for technical support to properly recommend wire.

Connecting the CLA Amplifier to AC Mains

DO NOT DO!

1. Never plug a CLA Series amplifier into a circuit without knowing what other products are connected to the same circuit.
2. Never plug a CLA Series amplifier into a power strip. Always connect directly to a dedicated circuit wall receptacle. Power strips are not designed to deliver high amounts of continuous or peak current.
3.  Never plug an CLA Series amplifier into an extension cord.

CLA (COMMERCIAL LITE AMPS) REQUIRE SPECIAL ATTENTION TO AC POWER
Know the type of outlet you are going to use and never use an adapter!

| Correct Outlet
120V – 20 Amp (NEMA5-20r)
---|---
| Correct Outlet
120V – 15 Amp
| Warning! Do Not Use
120V – 15 Amp to 20 Amp plug adapter

This example shows 3 x CLA amplifiers plugged into a power distribution strip in an amp rack. This shares the loads ofall three amplifiers on one 15A circuit. CLA amplifiers require a separate circuit for each amplifier to operate properly. This example shows a CLA amplifier plugged into an existing branch circuit in a building. Using this circuit to power a CLA amplifier is a bad practice because you can’t be sure how long the wire run is or how many loads are on the circuit. Branch circuits are designed for random use by peripheral devices and should never be used for AV system devices, especially CLA amplifiers.

BEST PRACTICE

This example shows a dedicated 120V 15 Amp service for the CLA amplifier. #14 wire is required for a 15 Amp circuit but may need to be up-sized based on the length of the panel-to-amp wire run. For the rest of he equipment in the head end rack, use a second dedicated 15 Amp circuit to the power strip.

Notes:

1. Power Level – Test is defined as follows: 1kHz sine wave signal burst of 20 cycles (20mS) at 1% THD+N, followed by 480 cycles of a 1kHz sine wave at 10% of the max Other power measurements available upon request. All power tests are done at 120V.
2. Average power draw is defined as Pink Noise input signal applied to achieve 1/4 of the 4W or 70.7V power rating.
3. Max pink noise power current draw is defined as Pink Noise applied as the signal source to the amplifier to achieve 100% of the 4W or 70.7V power rating. Using Pink Noise for testing amplifiers is a strenuous test that provides a consistent signal across the entire audio spectrum. Pink noise also provides a 6db Crest factor signal that injects a balance of RMS and peak signals providing realistic amp draw data for audio application.
4. Max burst power draw is defined as follows: 1 kHz sine wave signal burst of 20 cycles (40mS) at 100% of the 4W or 70.7V power rating, followed by 480 cycles of a 1 kHz sine wave at 10% of the max power repeated. Note: The amp draw / watt data is the peak power consumed and not steady state amp draw. This complies the UL 62368-1 standard and testing for maximum peak amp draw for a 120V 15A AC mains.
5. Music power draw is defined as dynamic input signal applied to achieve the maximum rated power into a 4W or 70.7V load. This test also represents realistic current draw data for audio applications. The current draw data is the maximum peak amp / watt and not steady state amp draw. This complies the UL 62368-1 standard and testing for maximum peak amp draw for a 120V 15A AC mains. Note: When specifying this amp for power consumption, we recommend using the Max Music Power Amps / Watt rating data.
6. Sine wave power draw is defined as 1 KHz input signal applied to achieve the maximum power output before clip into a 4W or 70.7V load. This data should be used as a reference of the maximum current the amplifier can draw. Steady state sine wave signals over 3 seconds should not be applied and may drip a 15A 120V AC Mains breaker.
7. 25V Systems use 4W Load Selection Settings, CLA402 & CLA804 Power Share 200W Setting Equal 150W, CLA202 & CLA404 Power Share Setting 100W Equal 100W.
8. 2W loads use 4W Load Selection Settings, CLA402 & CLA804 Power Share 200W Setting Equal 100W, CLA202 & CLA404 Power Share 100W Setting Equal 50W.
