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
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.
Use the PowerShare Design Tool (found at BoseProfessional.com) to help plan your system design.
A.
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 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 in 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 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 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.
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 combining with PowerMatch PM8500N, add 1.5 ms latency to PowerMatch to match the increased latency of PowerShareX.
•
To set 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; 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 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.
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 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 dust from the filters, or wash them with clean water. Let the filters dry thoroughly before
reinstalling them.
