1.Power Switch – to turn unit on after you have turned on all input devices and before you turn on any devices attached to the output.

2.Power Supply Input - to plug your power adapter in before switching on power. See safety precautions on page 3 for proper treatment of power.

3.Mic Process Send – attach this output to any devices you would like to process the microphone with. This output is activated by the front panel mic process button.

4.Mic Process Return – bring your processed mic signal back in through this input.

5.Phono/Auxiliary Inputs – plug your turntables or line device in here. Select the AUX/PHONO switch (6) to the desired input.

6.Phono/Auxiliary switch – select the appropriate position for your input device. With phono selected the input signal is fed directly to the PRO SM-1's high-quality RIAA phono pre-amplifiers so use this input only for turntables. Line level sources will overload the sensitive phono pre-amps. Switch this over to the AUX position for line devices such as CD players and Tape decks.

7.Ground lug - use these connections with your turntables’ grounding cable to avoid signal hum.

8.Line Inputs - to connect stereo audio from HiFi VCRs, cassette and reel-to-reel tape decks, DAT machines, CD players, laser discs, tuners, even synthesizers or other mixing consoles.

NOTE: Plug mono audio sources into both Left and Right inputs using a “Y" cable connector.

9.Zone Output - an unbalanced output controlled by Zone Level control on the face panel for extra speakers, lighting, or recording your mix..

10.Zone Stereo/Mono Switch - allows the user to adjust the signal accordingly.

11.Unbalanced Main Outputs – program output controlled by the Master fader knob.

12.Channel Send – The output is determined by pushing the front panel process selectors next to each channel.

Note: this mixer was design to use one processor for many channels, If more than one channel is selected than the signal will bleed across the channels. This can be a desired effect if you wish to blend wet a dry signal. Sent signal is captured after the PFL gain and prior to EQ and Pan adjustments allowing the user total control of the processed signal.

This output has been designed to work for a variety of send options.

a.Sampling - the send should be plugged into your sampler and the signal returned through one of your inputs.

b.Processing – the send should be plugged into your external processor. Plug you processor return into the Channel Return (13).

13.Channel Return – Plug the outputs of your processor to this input. Set the output level of you processor to match the signal it receives from the send to ensure smooth activation. With proper level adjustment you can create smooth transitions between processed and unprocessed signal.

Note: If no device is plugged into the return and a signal is sent to the Channel Send then that signal will not be interrupted. By plugging into the return jack, the mixer will route returned signal to replace the sent signal. In this way a sampler can be used without interrupting live signal. You also could use this return as a ¼” line input that can be selected to any channel when the process button is activated.

14.Balanced Outputs - These 1/4" Stereo Main Outputs are reliable Balanced TRS 1/4" connectors controlled by the Master fader knob. Power transformers and other devices which cause magnetic fields can induce hum in audio cables. This can be best resolved by using balanced lines where inputs and outputs permit. Balanced lines are also the most effective means of reducing or eliminating RF or radio frequency" interference.
