Setting Up the PowerShare Ampliﬁer

The asymmetrical PowerShare capability of the ampliﬁer is easy to use and does not require software to

conﬁgure. Set the output trims according to the power you want distributed to each output load and the

ampliﬁer ensures that the 600 watts (PS604D), or 400 watts (PS404D), power is not exceeded. In scenarios

where more power is demanded from the ampliﬁer, the ampliﬁer will automatically limit all outputs equally

until the power demand is reduced.

How to Set Up a PowerShare Ampliﬁer:

1. Starting with the ampliﬁer power OFF, make all required power and audio connections.

2. All conﬁguration is done within ControlSpace Designer software:

A. Connect the PC or laptop to either ampliﬁer's Dante port, or connect to the ampliﬁer via a network

switch.

B. Turn the ampliﬁer ON.

C. Start the ControlSpace Designer software on your PC or laptop and conﬁgure each signal processing

block as required for the application. See the ControlSpace Designer help system for details.

D. Inputs are analog by default to ensure audio can pass through the ampliﬁer with no programming

necessary. Use ControlSpace Designer to change each input from analog to Dante® as necessary.

3. If using CC-D ControlCenter digital zone controller(s) for remote control, rotate each Output Attenuation

control fully clockwise to 0 dB attenuation. This enables each CC-D zone controller to attenuate over the

full range. To have the CC-D operate across a limited range, increase the output attenuation as needed by

rotating the Output Attenuation control counter-clockwise.

4. If all outputs are set to drive 70/100-volt Hi-Z loudspeakers, rotate each corresponding Output Attenuation

control 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. For examples, see the

PowerShare Application Guide at pro.Bose.com.

5. If all outputs are set to drive 4-8 Ω Low-Z loudspeakers, rotate each Output 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. Observe the Output Limit LED

for the output being adjusted. If the signal level is higher than the protection limit for the loudspeaker,

the Output Limit LED will light amber. Increase the attenuation until the Output Limit LED does not light,

or only occasionally lights. The total ampliﬁer wattage can be distributed in any way across all ampliﬁer

outputs. For examples, see the PowerShare Application Guide at pro.Bose.com.

6. 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.

7. When setting up the ampliﬁer, monitor the Input Signal LEDs for input clipping and the Output Limit LEDs

for output limiting to ensure the ampliﬁer is working within proper operating conditions. Make adjustments

if necessary.
