Hook-Up

CA Series Controls

Controls

1. EQ knobs – Adjusts the bass and treble for the master output(s).
2. Master volume – Controls the overall output level. The associated LED(s) will light green to indicate active signal, and light red to indicate limiting/protection.
3. Power button – Turns the unit on, force it to stand by. The LED will indicate power status.
4. Mains connector – Connect the IEC cable to a mains outlet.
5. Config switches – Configure the output channel for the connected load type. See ‘Getting Started’ section for details.
6. Output – Connect your speaker(s).
7. Remote – Allows the connection of an external volume control module per channel. CRC-V available as a separate accessory.
8. Euroblock input – Accepts 3-pin Euroblock connectors for balanced line-level sources. For the 2-channel models, Input A is routed to Output A only, and Input B is routed to Output B.
9. RCA inputs – Allows the connection of stereo unbalanced sources, which will be summed to mono and routed to the associated output (Input A to Output A).
   For the 2-channel models, stereo operation can be achieved by connecting the left signal to Input A and the right signal to Input B.

CA Series Getting started

Welcome to the CA series Quick Start Guide and thank you for purchasing one of these amplifiers. The following accessories should be included with your product:

• Euroblock input connector(s)
• Euroblock output connector
• Coupling plate (x2) with necessary screws
• Long angle bracket
• Front angle bracket (x2)
• Rear flat bracket
• Rear angle bracket with shoulder screw
• Power cable with mains plug corresponding to the specified country version
• Quick Start Guide (this document)

Rack Mounting
The CA series amplifiers come with rubber feet that enable the amps to be placed on a clear surface without an additional installation. However, optional rack mounting hardware is also supplied, allowing several models to be housed and protected inside an enclosure. Follow these steps to attach the mounting hardware. A pair of CA units can be mounted side-by-side to occupy a single rack space. Attach the coupling plate to the underside of 2 CA units using the included screws.

Attach the front angle brackets to either side of a pair of CA units that have been coupled. Alternatively, a single CA unit can be installed in a 19″ rack using the long angle bracket, or in a half 19″ rack using the short angled brackets. Attach the angled brackets, by unscrewing the chassis side front screws and attach again together with the brackets.

If your rack has rear rails, attach the rear flat brackets by reusing the screws from the chassis.

Mount the CA units into the rack by attaching 4 rack screws through the front angle brackets and rack rails.
Hold one of the rear angle brackets up to the rear rack rails so that it lines up next to the rear flat bracket. Do not attach it to the rear rails yet.
Insert the included shoulder screw through the slot in the rear flat bracket and into one of the threaded holes in the rear angle bracket. The screw should allow the rear angle bracket to slide forward and back within the flat bracket’s slot.

• Repeat the process for the other rear angle bracket.
• Mount the rear angle brackets to the rear rack rails using 4 standard rack screws.
• Tighten the shoulder screw if necessary.
• The standard rack screw is M4 x 8mm.
• The CA series amplifiers are convection cooled and primarily use the top surface to dissipate heat. For demanding applications, it is recommended to have sufficient space (1 RU) above the amplifier to reduce the risk of limiting due to overheating.

Table/Wall Mounting
Connect a pair of coupling plates to either side of a CA series amplifier, then mount screws through the remaining holes in the plates to secure the unit to a wall or table.

Connections
For balanced input connections, use a 3-pole cable (hot, cold, ground) wired to a Euroblock connector. Alternatively, RCA cables can be connected for unbalanced stereo sources, but the RCA and Euroblock inputs should not be used together on the same input. Note that stereo RCA signals will be summed to mono.

3-Pin Euroblock Connector – Input

For output signals, connect a 4-pole (2-pole for CA601/1201/2401) Euroblock connector to the main output connector. Do NOT connect any terminal to ground. Do NOT connect the cold (-) terminals together for common returns. Make sure to set the Config switches in the correct position to match your intended use. Speaker wire of 14-18 AWG (0.8 to 2.5 mm) is recommended for connections up to 50 feet.

Config

• The first 2 Config dipswitches allow the output to be configured for 100 V, 70 V, 8 Ω, or 4 Ω operation. Always use the correct configuration for the speakers being driven! The mode of operation configures both the maximum voltage of the output and the gain through the device.
• The 8 Ω setting should be used for a pair of 16 Ω speakers or a single 8 Ω speaker. The 4 Ω setting should be used for 4 x 16 Ω, 2 x 8 Ω, or a single 4 Ω speaker. Use 70 or 100V setting for Constant Voltage high impedance speaker systems. Make sure the sum of the power tapping on the speakers plus margin does not exceed the amplifier’s maximum power rating.
• The 3rd dipswitch engages a high-pass filter at 80 Hz, which should be used on all Constant Voltage systems to avoid saturation on the transformer-enabled speakers, but can also be used to help maintain clear sound from small speakers or bass-heavy audio.

Remote

RJ45 receptacle to connect an optional remote volume control per channel. Use a standard cable to connect the CRC-V accessory. Or connect a custom potentiometer with the pinout information. Cable length above 305m (1000ft) is not recommended.

Signal Wake-up
If the amps are powered on, but do not receive any input signal (below signal present level) for 20 minutes, the system will enter standby mode to save power consumption. As soon as a signal is detected at any input, the unit will exit standby mode and resume normal function.
