Russound P75 Two-Channel, 75W, Dual Source Amplifier

The P75 is a 2-channel dual source power amplifier with autosource switching. It features two audio line inputs with a loop out to another zone, receiver, or device from Line 2 source. This amplifier can be used for power upgrades in specific zones, for speaker selector or volume control systems.
 

The P75 is a Class A/B amplifier rated at 75 watts per channel into 4 ohms, and 60 watts into 8 ohms. With the Stereo/Bridge Mono switch in Bridge Mono position, both amplifier channels are combined for a higher powered mono output. In Bridge mode the P75 is rated at 160 watts of power into a single 8 ohm load.
 

Not available to countries requiring CE certification. 110v only.
 

Features:

• Built for multi-speaker applications with volume controls
• Automatic switching between two sources with signal sensing
• Front panel volume and balance controls-Channels are bridgeable to create one channel with 160 watts of power

Using the P75 with a Single Audio Source:

The P75 is a versatile 2-source amplifier with automatic switching.  Assuring that all connections are made properly is critical to that functionality. When using a single audio source however, we frequently get asked about how to make the connection on the rear of the P75. Over the lifetime of the P75, there have been several different labeling variations used on our P75 to explain the connections, but the main audio source input, also known as the “Default” always uses the same physical location on the rear of the P75 as shown below.

Troubleshooting Tips:

• If you’re hearing dropouts happening during music playback, make sure that your default audio device is connected to the input shown above.
• If you are using two audio sources on the P75, make sure the default source, the one that you want to listen to most frequently, is connected to the “Default In” connection as shown above. The second source that you want to have automatically become the P75’s active source should be connected to the other input, the one on the left in the illustrations above.
