Output Attenuation controls: Output attenuation controls for each output. Turn the controls clockwise to decrease attenuation and
counter-clockwise to increase attenuation. The attenuator must be at 0 dB attenuation for the respective output to reach rated power.
Mute: Normally open or normally closed dry contacts can mute all outputs. Mute polarity can be inverted by a DIP switch.
Output terminal block: 4-terminal block connector for loudspeaker connections. Each channel can deliver up to 600 watts (P2600A) or up to 1000 watts (P21000A) regardless of load into 4Î©, 8Î©, 70V, or 100V. Outputs can be I-Shared.
DIP switches: A bank of switches used to set amplifier configuration.
Auto Standby: If enabled (On), the amplifier goes into lower-power mode after 20 minutes without an input signal. If in lower-power mode and an audio signal is detected, the amplifier will automatically wake and amplify audio within one second. The default position is Off.
Mute Polarity: Switch mute polarity between NO (normally open) or NC (normally closed). NO is the default position.
Global Out: Sets the output capability to 70V or 100V for all outputs that have their DIP switch set to Hi-Z. In 70V Hi-Z mode and Low-Z mode, 100 VP and 70 VRMS limiters are automatically loaded. In 100V Hi-Z mode, 100 VRMS limiters are automatically loaded.
Output 1: Select 70/100V high-impedance output (Hi-Z) or 4–8Ω low-impedance output (Low-Z) for Output 1.
Output 2: Select 70/100V high-impedance output (Hi-Z) or 4–8Ω low-impedance output (Low-Z) for Output 2.
I-Share 1 & 2: Deliver 2× channel power by combining the current of Outputs 1 & 2. While the amplifier is off or in Standby mode, set this DIP switch to On and install the included jumper across the four-output terminals. Then wire the loudspeaker load to the amplifier using terminals 1+ and 1– (or 2+ and 2–).
Input Select control: Dial selects if analog or AmpLink audio inputs are used. The default state is analog 1:1.
AmpLink ports: Input RJ-45 connector that receives up to eight digital channels from a Bose AmpLink product. The amp also supports a Thru path for daisy-chaining all eight digital audio channels to up to eight other Bose AmpLink products, at a maximum distance of 10 meters between products.
Analog Input: Line-level input for balanced analog audio signals.
Update port: Used for firmware updates.
Gain/Sensitivity switch: Slide switch to set global gain/sensitivity setting to high gain (â€“10 dBv sensitivity), mid gain (4 dBu sensitivity), or low gain (14 dBu sensitivity).
Power input: Power cord connection (IEC 60320-C14 inlet). Removing the power cord when the amplifier is on is an acceptable power- down method.

Setting Up a PowerSpace Amplifier

Starting with the amplifier power Off, set the rear-panel switches as needed for the application. Then make all required power and audio connections.
Press the Power switch on the front panel to power the amplifier On.
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 standard 48-centimeter (19-inch) rack equipment, occupying one rack-unit (RU) in height (4.4Â 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.

Mute with Standard Contact Closure

BOSE P2600A PowerSpace Versatile Power Amplifiers 6
The ampliﬁer is designed to mute all outputs either when the Mute contacts are shorted together, or when the Mute contacts are opened, depending on the ampliﬁer conﬁguration. The default state is Normally Open (NO), where a short across the Mute connector will mute all outputs. You can use the Mute DIP switch to invert the mute polarity to Normally Closed (NC), where an open circuit across the Mute connector will mute all outputs.
Note: All Output Limit LEDs will blink red when the amplifier is muted from the rear panel Mute connector.
