P75 Amplifier (PZA)
P75 Dual Supply Amplifier, Two Channel, 75W
The P75 is a 2-channel dual-supply power amplifier with automatic source switching. It has two audio line inputs with a loop to another zone, receiver or device from the Line 2 source. This amplifier can be used for power enhancements in specific areas, for speaker selection or volume control systems.
Using the P75 with a single audio source:
The P75 is a versatile 2-source amplifier with auto-switching. Ensuring all connections are made correctly is critical to that functionality. However, when using a single audio source, we are often asked how to make the connection on the back of the P75.
Over the P75's lifespan, several different labeling variations have been used on our P75 to explain the connections, but the main audio source input, also known as "Default," always uses the same physical location on the back of the P75 as shown below.
Troubleshooting Tips:
- If you experience interruptions during music playback, make sure 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 you listen to most often, is connected to the "Default Input" connection as shown above. The second source that you want to automatically become the P75's active source should be connected to the other input, the one on the left in the illustrations above.
