Technical Considerations; Care And Maintenance - Bose PowerShareX PSX1204D Installation Manual

Installation
Setting Up a PowerShareX Amplifier
1. Connect power cable to the amplifier and connect it to an appropriate power source.
2. Be sure the amplifier power is set to Standby by viewing the Operating Mode LED. If the amplifier is On, press and hold the
Power button for three seconds to switch to Standby.
3. Make all output and input audio connections.
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.
4. To configure the amplifier in ControlSpace Designer, connect your computer to your amplifier's Ethernet port using a Cat 5e
cable, or use a network switch.
5. 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 both analog and digital inputs.
ControlSpace Designer can be used to select an input type.
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.
7. Configure your loudspeakers by adjusting the Output Configuration DIP switches and the System Configuration DIP switches to
the desired parameters for your installation.
If all outputs are set to drive 70V/100V Hi-Z loudspeakers, rotate each corresponding Channel Attenuation control 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.
If all outputs are set to drive 2Ω Low-Z loudspeakers, rotate each Channel Attenuation control until the desired levels are

reached. Play a signal containing the highest normal program or pink noise input level. Ensure the material is near the input
sensitivity for best noise performance. 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.
When setting up the amplifier, monitor the Channel Status LEDs for input clipping and the System Status LEDs for operating

faults. Make adjustments if necessary.

Technical Considerations:

When a loudspeaker EQ is selected in ControlSpace Designer, the appropriate crossover and V
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 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.
• Adjust the transformer tap settings of any connected Hi-Z loudspeakers.
• Analog outputs can also be attenuated with the GPI/Remote connector.
Networking
PowerShareX amplifiers have two RJ45 Ethernet ports: the Ethernet port is for network communication/control; 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.
A static IP is recommended and can be configured though 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. If using a DHCP server it is recommended to turn on the DHCP server before connecting the amplifier to ensure a valid IP
address is acquired.
Care & Maintenance
When cleaning the amplifier, keep the following in mind:
• Use a dry cloth for cleaning the chassis and the front panel. Air filter cleaning should be scheduled in accordance with the dust
levels in the amplifier's operating environment.
• In order 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 the dust from filters, or wash it with clean water (let the filter dry thoroughly before reinstalling
them).
