If using ControlCenter analog zone controller(s) for remote control, rotate each Output Attenuation control fully clockwise to 0 dB

attenuation. This enables each zone controller to attenuate over the full range. To have the zone controller operate across a limited

range, increase the output attenuation as needed by rotating the Output Attenuation control counter-clockwise.

Depending on the loudspeakers you are configuring with your PowerSpace amplifier, 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, the amplifier

will deliver the required power to each output, up to the rated channel power. For examples, see the PowerSpace Application

Guide at PRO.BOSE.COM.

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. 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. For examples, see the PowerSpace Application Guide at PRO.BOSE.COM.

Since each output is configurable to drive either high-impedance or low-impedance loudspeakers, the amplifier can support mixed-

impedance installations. In this setup, first configure the high-impedance channels before configuring the low-impedance channels.

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.

Technical Considerations:

Adjusting the Output Attenuation control of a single channel does not affect the level of other channels. Each channel will limit to its rated

power. If the continuous power demand remains too high, the amplifier will gradually limit to an average of 1/3 power continuously.

There are multiple ways to adjust output power in a PowerSpace amplifier application:

•

Adjust input signal level relative to the sensitivity setting of the amplifier.

•

Adjust the Output Attenuation controls of the amplifier.

•

Adjust the transformer tap settings of any connected high-impedance loudspeakers.

Setup Placement

CAUTION: This product is not intended for installation or use in indoor water facility areas (including, without limitation, indoor

pools, indoor water parks, hot tub rooms, saunas, steam rooms and indoor skating rinks).

CAUTION: Do not mount the product in locations where condensation may occur.

Importance of Proper Ventilation

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.

CAUTION: Due to ventilation requirements, do not place the product in a confined space such as in a wall cavity or in an enclosed

cabinet. Do not allow the chassis to exceed the maximum operating temperature of 40 °C (104 °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 a

thermal protection mode and mute all outputs.

Rack Mounting

PowerSpace amplifiers are designed to fit standard 48-centimeter (19-inch) rack equipment, occupying one rack-unit (RU) in height

(4.4 cm/1.7 in), requiring a mounting depth of 40.6 centimeters (16.0 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.

CAUTION: Only use the mounting hardware recommended by the rack manufacturer.

CAUTION: Do not place or install the bracket or product near any heat sources, such as fireplaces, radiators, heat registers or other

apparatus (including amplifiers) that produce heat.
