To set up the PowerSpace amplifier for your specific loudspeakers, follow these steps:

1. Start with the amplifier power off and set the rear-panel switches as needed for your application.
2. Make all required power and audio connections.
3. Press the Power switch on the front panel to power the amplifier on.
4. Depending on the type of loudspeakers you are using, do one of the following:
   - If all outputs are set to drive 70/100V high-impedance 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.
   - If all outputs are set to drive 4-8Ω low-impedance 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 and adjust the attenuation until the Output Limit LED does not light or only occasionally lights.

Note: Each output can be configured to drive either high-impedance or low-impedance loudspeakers, allowing for mixed-impedance installations. When setting up the amplifier, monitor the Input Signal LEDs for input clipping and the Output Limit LEDs for output limiting to ensure proper operation. Adjustments may be necessary.
