The Facts about Mini Mixers
Problem: How do you connect a CD player, a synthesizer and the line output from a bass amp to a tape deck?
Solution: Use a simple stereo mixer. The PowerMIX III can accept either mono or stereo signals and mixes them down to stereo or identical L/R mono signals. Additionally, the PowerMIX III provides a headphone output with its own level control.

- A Master Level control regulates all 3 channels
- Left and Right unbalanced 1/4" Outputs
- The Headphone channel features dual, stereo 1/4" outputs so that two headsets can be connected at once

Usage
- Plug the AC adapter into the 12V DC input on the PowerMIX III and plug the other end into a 120V AC wall socket.
- Plug your stereo signal sources into the separate L/R Inputs on channels 1 to 3. Mono sources can be plugged into the Right Input on any channel. It is not recommended that you connect 2 mono sources to any one channel.
- Connect the L/R Outputs to the inputs on your mixer, tape deck, PC, etc. with unbalanced, shielded patch cables.
- Connect stereo headphones to either of the Headphone jacks. An additional set may be connected to the remaining jack. Turn up the Headphone Level slightly.
- Adjust the channel Pan and Level controls for the desired mix through headphones.
- Increase the Master Level control setting as required for optimum signal level and clarity from the recording or PA device (PC, cassette deck, mixer, etc.).
A block diagram illustrates the signal flow. Inputs for Channels 1, 2, and 3 are shown with associated Pan and Level controls. These are mixed into a Master Level control, which then feeds Left/Right Outputs and a Headphone section. The Headphone section has its own Level control and dual headphone outputs.
