ControlSpace Designer

• Before configuring your PowerShareX amplifiers, download the latest version of ControlSpace Designer at BoseProfessional.com.
• If all the network connections and settings are done correctly, ControlSpace Designer should automatically identify the PowerShareX amplifier on the network.
• Connect the PowerShareX to the ControlSpace network, power on the amplifier, and open ControlSpace Designer to discover, update, and configure the amplifier.
• For full details on using ControlSpace Designer to configure, control, and monitor the amplifier or systems built with Bose Professional networked system electronics, consult the ControlSpace Designer help system.

Setup Placement
For placement of the amplifier, keep the following in mind:

• Make sure that air can circulate freely from front to back for adequate ventilation. There are vents on the front, back, and sides of the amplifier.
• Do not cover or block amplifier vents.
• Make sure the chassis is protected from heat and kept away from direct heat sources, such as heating vents and radiators.
• Secure both front and rear brackets to the rack.
• Connect the AC Mains connector to a circuit breaker.
• Install the amplifier far from EMF-emitting devices.
• Avoid placing the amplifier close to heat-generating sources.

Rack Mounting

• CAUTION: Leave 1 RU of space between every collection of four amplifiers to guarantee adequate airflow.
• CAUTION: Due to ventilation requirements, do not place the product in a confined space such as in a wall cavity or an enclosed cabinet. Do not allow the chassis to exceed the maximum operating temperature of 35 °C (95 °F). Be aware of conditions in an enclosed rack that may increase the temperature above room-ambient conditions. If the amplifier becomes too hot, it will go into thermal protection mode and mute all outputs. PowerSpaceX amplifiers are designed to fit standard 48-centimetre (19-inch) rack equipment, occupying one rack-unit (RU) in height (4.4 cm/1.7 in), requiring a mounting depth of 35.8 centimetres (14 inches) from the front rack rail. Use four fasteners with washers (not supplied) to mount the amplifier front panel rack ears to the equipment rack rails.

Cooling

• The ventilation openings must not be impeded by any item, keep a distance of at least 50 mm from the front and rear ventilation openings of the amplifier.
• PowerShareX amplifiers implement a forced-air cooling system to maintain constant operating temperatures. Air enters from the front panel, exiting at the back of the amplifier.
• The cooling system features variable-speed DC fans controlled by the heat-sink mounted sensors. This ensures that fan noise and internal dust accumulation are kept to a minimum.
• In the rare event of overheating, sensing circuits shut down all channels until the amplifier cools down to a safe operating temperature. Normal operation is resumed automatically without the need for user intervention.

Rear Panel

1. Power input: Power cord connection. Removing the power cord when the amplifier is on is an acceptable power-down method.
2. Output Configuration DIP switches: Any mixed configuration of low and high impedance output loads can be made using the four switches for each channel.
   • 70V/100V: Switch the channel output operation between 70 volts and 100 volts.
   • Lo-Z/Hi-Z: Switch the channel output impedance between low impedance and high impedance.
   • 35Hz/70Hz: Switch the high pass filter frequency between 35 Hz and 70 Hz.
   • HPF Off/HPF On: Activate or deactivate the channel output high-pass filter. Recommended for 70V/100V outputs if software bandpass high-pass is not engaged.
3. Output connector: An eight-terminal connector for loudspeaker connections. Each channel can deliver up to 300 watts (PSX1204D), 600 watts (PSX2404D), or 1200 watts (PSX4804D) of symmetrical power.
4. Remote Level connector: The level of each channel can be adjusted remotely by a remote level control (linear 10 kΩ potentiometer) connected to the input LEVEL connector for that channel. Connect to Channel 1 and set CH1 MSTR DIP switch to On to control all four channels from one controller. Alternatively, to enable remote level adjustment of two or three channels simultaneously, connect the potentiometer’s resistive variable pin to multiple channels in parallel (refer to the example diagram where the potentiometer is controlling Channels 1–3). The remote level controls are in series with the Channel Attenuation controls.
   • Note: ControlCenter CC-1, CC-2, and CC-3 are not compatible with PowerShareX amplifiers.
5. Line Input connector: Line-level input for balanced analog audio signals.
6. GPI/Remote connector: Remote on and off control. Both pair of terminals respond to the differential voltage between the contacts: a voltage difference between 5 VDC and 24 VDC triggers the control. Remote off can be used to mute the amplifier. The terminals act differently depending on the actual state of the amplifier:

exits standby; ON LED lights solid green
Amplifier is On| V ³ 5V applied to REMOTE OFF only| Amplifier enters standby; SDBY LED lights solid orange –6dB/TEMP LED steady flashes yellow
Amplifier is in either state| V ³ 5V applied to REMOTE ON and REMOTE OFF simultaneously| Amplifier exits standby; ON LED lights solid green; If amplifier is already on, no change
V < 3V applied to REMOTE ON and REMOTE OFF simultaneously| No change

Voltage applied to contacts

Vdiff < 3V

|

Vdiff ³ 5V

Vdiff ³ 5V

|

Vdiff ³ 5V

Vdiff < 3V

|

Vdiff < 3V

CAUTION: Any voltage exceeding 28 VDC may damage the input circuitry.
System Configuration DIP switches: DIP switches to control overall system output and performance.

• CH1 MSTR: When the CH1 MSTR switch is OFF, remote-level potentiometers work independently for each channel. When the CH1 MSTR switch is ON, the remote-level potentiometer of Channel 1 acts as a master level, controlling the volume of all four channels.
• GAIN: Adjust the global input gain sensitivity to 35 dB, 32 dB, 29 dB, or 26 dB by following the configuration diagrams on the rear of the amplifier. This feature is designed to match the voltage of the input signal. PowerShareX amplifiers ship with gain sensitivity set to 32 dB by default.
• Note: For most situations, leave this set to 32 dB gain. The 35 dB gain setting is similar to PowerMatch 8500N (36 dB). Analog gain sensitivity cannot be further adjusted through ControlSpace Designer. Digital input sensitivity can also be adjusted through ControlSpace Designer.
• BRK SAVE (Breaker Save): Switch to ON when (1) the power grid is unable to provide enough current to continuously drive the loads, or (2) when at least one of the amplifiers connected to the same outlet can reach the critical power absorption of the line. When activated, the Breaker Save halves the maximum continuous current absorption from the mains, which reduces the available output power. This will be indicated by the LIMIT System Status LED on the front panel. This will affect overall performance of the amplifier.
• NRG SAVE (Energy Save): The power supply unit allows a reduction in power consumption when the input signal falls under a defined threshold. When ON, Energy Save is active on each channel independently. If the signal is absent for more than 30 minutes on all channels, auto standby is applied and the main PSU is turned off to further conserve energy (Time out time is selectable via ControlSpace Designer). Normal operation resumes immediately upon detecting a signal.
• Note: USR A, USR B, and USR C (PSX4804D only) are unavailable.
• 2Ω: PowerShareX amplifiers are optimized for working with 4Ω output loads, but the 2Ω switch allows loads down to 2Ω. Switch to ON to activate an operating condition that optimizes the performance with very low loads by limiting the maximum output voltage to 85 VPeak per channel. This affects all output channels set to match low impedance (i.e. in Lo-Z configuration). For optimal 2Ω performance, switch the Lo-Z/Hi-Z Output Configuration DIP to Lo-Z for all channels.
• Note: PSX1204D and PSX2404D only. PSX4804D can also handle 2Ω loads without the use of a DIP switch.
• Ethernet port: RJ45 connector. Remotely control the amplifier via an Ethernet connection through a personal computer and ControlSpace Designer software.
• GPO/Alarm connector: There are general-purpose output connections for each channel: one Normally Open (NO), one Normally Closed (NC), and one channel number connection that acts as a ground (1–4). At least two connections are required to report and detect a change (e.g., 3 and NC). When the amplifier is in normal operating condition, the NO contacts are closed and the NC contacts are open. These contacts are toggled to indicate a potentially dangerous fault, unsafe operating condition, or any fault preventing normal output channel operation, including the following:

Analog Input to Achieve Full Scale

| PSX1204D| PSX2404D| PSX4804D
---|---|---|---
Input sensitivity @ 8 Ω with 26 dB Gain| 2.48 VRMS| 3.54 VRMS| 4.91 VRMS
Input sensitivity @ 8 Ω with 29 dB Gain| 1.76 VRMS| 2.51 VRMS| 3.48 VRMS
Input sensitivity @ 8 Ω with 32 dB Gain| 1.24 VRMS| 1.78 VRMS| 2.46 VRMS
Input sensitivity @ 8 Ω with 35 dB Gain| 0.88 VRMS| 1.26 VRMS| 1.74 VRMS
Across all channels:| No AC mains (i.e. system shutdown). Thermal stress: the system temperature is too high and the thermal protection is engaged. Amplifier is in standby mode.
---|---
Affected channels only:| Short circuit in output wiring: either the loudspeaker or the line is in short. Alarm is sent out the specific output channel with the short circuit event.

NC/NO connections of multiple channels can be combined if needed. See ControlSpace Designer for additional alarm and monitoring options.
Dante port: RJ45 connector. PowerShareX accepts four input streams from the Dante® connection through the Dante port. Use a computer running Dante Controller to implement a Dante network. Dante Controller is a software application that manages devices on the network.

Installation

Setting Up a PowerShareX Amplifier

1. Make all output and input audio connections.
2. Connect your computer to your amplifier’s Ethernet port using a Cat 5e cable, or use a network switch.
3. Connect Dante network audio to the amplifier’s Dante® port.
4. Ensure all Channel Attenuation front panel controls are fully clockwise or at their desired levels. This affects analog, Dante, and pink noise levels.
5. Configure your loudspeakers by adjusting the Output Configuration DIP switches and the System Configuration DIP switches to the desired parameters for your installation.
   • A. Use the PowerShare Design Tool (found at BoseProfessional.com) to help plan your system design.
   • B. If outputs are set to drive 70V/100V Hi-Z loudspeakers, ensure Channel Attenuation control is fully clockwise to 0 dB attenuation. Set each loudspeaker tap to the appropriate setting. Based on the total loudspeaker tap settings, the amplifier will adapt and deliver the required power to each output. The total amplifier wattage can be distributed in any way across all amplifier outputs.
   • C. Since each output is configurable to drive either Hi-Z or Low-Z loudspeakers, the amplifier can support mixed-impedance installations. In this setup, first configure the Hi-Z channels before configuring the Low-Z channels.
6. Configure any remote controls using the Remote Level connector.
   • A. If using a potentiometer for remote control, rotate each Channel Attenuation control fully clockwise to 0 dB attenuation. This enables each controller to attenuate over the full range. To have the controller operate across a limited range, increase the attenuation as needed by rotating the Channel Attenuation control counter-clockwise.
   • Note: There is no ground switch or terminal on PowerShareX amplifiers. The unit’s signal grounding system is automatic. In order to limit hum and/or interference entering the signal path, use balanced input connections.
7. Connect the power cable to the amplifier and connect it to an appropriate power source.
8. Start ControlSpace Designer on your computer and configure each signal processing block as required for the application. See the ControlSpace Designer help system for details. By default, sources are configured for analog inputs and must be changed to digital if Dante network audio is desired. ControlSpace Designer can be used to select an input type.
9. If the amplifier is on Standby, press and hold the Power button for three seconds to turn on the amplifier.
10. When setting up the amplifier, monitor the Limit indicators for each channel in ControlSpace Designer (while the amplifier is on-line) and the System Status LEDs on the front amplifier for operating faults. Make adjustments if necessary.

Technical Considerations

When a loudspeaker EQ is selected in ControlSpace Designer, the appropriate crossover and VPeak and VRMS limiters for that loudspeaker are automatically loaded. Adjusting the Channel Attenuation control of a single channel does not affect the level of other channels. The only exception is if the amplifier is attempting to deliver more than the total amplifier wattage. If the total amplifier power is exceeded, the amplifier will limit all outputs simultaneously and equally until the demand is reduced. If the demand remains too high, the amplifier will gradually limit power.
There are multiple ways to adjust output power in a PowerShareX amplifier application:

• Adjust the input signal level relative to the sensitivity setting of the channel.
• Adjust the Matrix level in ControlSpace Designer.
• Adjust the output levels in ControlSpace Designer.
• Adjust the Channel Attenuation controls of the amplifier.
• Adjust the limiter settings for each output using ControlSpace Designer.
  • CAUTION: Increasing the voltage to a level higher than the preset may damage the loudspeaker.
• Adjust the transformer tap settings of any connected Hi-Z loudspeakers.
• Mute analog outputs with the GPI/Remote connector, switching the amplifier to standby.
• If combined with PowerMatch PM8500N, add 1.5 ms latency to PowerMatch to match the increased latency of PowerShareX.
• To set the amplifier for Auto Standby, use the NRG Save DIP switch and select Auto Standby in ControlSpace Designer.

Networking

• PowerShareX amplifiers have two RJ45 Ethernet ports: the Ethernet port is for network communication/control; and the Dante port is for
• Dante streaming audio. Two separate Cat 5e cables are needed to use both ports. PowerShareX amplifiers do not support bridging with a single cable.

IP Addressing

• Factory default network settings are DHCP.
• If using a DHCP server, it is recommended to turn on and connect the DHCP server to the network before powering on the amplifier to ensure a valid IP address is acquired.
• A static IP is recommended and can be configured through ControlSpace Designer. The amplifier and ControlSpace Designer must belong to the same subnet to be discovered and configured though ControlSpace Designer.
• If a DHCP server is not present while the amplifier boots, the amplifier will be configured with a link-local address in the 169.254.0.0/16 subnet.

Care & Maintenance

When cleaning the amplifier, keep the following in mind:

• Use a dry cloth to clean the chassis and the front panel.
• Vent filter cleaning should be scheduled following the dust levels in the amplifier’s operating environment.
• To clean the vent filters remove the front panel faceplates by pulling them away from the amplifier to disengage the magnets.
• Use compressed air to remove dust from the filters, or wash them with clean water. Let the filters dry thoroughly before reinstalling them.
