2. Inputs & Outputs – the Back Panel
1. Effect send/return stereo RCA connectors: allow you to apply external sound effects to the final mix.
2. Channel inputs: stereo RCA connectors for high level audio sources. 2 inputs have a line/phono switch (5).
3. Ground connector: for turntables; of the screw nut type.
4. Mic2 ¼" (6.35mm) connector: for either a balanced or unbalanced low impedance microphone, or an unbalanced
high impedance microphone.
5. Line/phono switches: enable you to connect 2 turntables to this mixing panel.
6. High impedance master outputs: either by 2 RCA connectors or 2 ¼" (6.35mm) connectors.
7. Zone output: high impedance RCA connectors for extra master mix output
8. Recording output: high impedance RCA connectors to record final mix.
9. Power connection: connect the mixing panel to an AC power source; make sure the switch is set to the correct
voltage.
3. Installation
a) Inputs
The PROMIX400SF2 allows connection of up to 8 audio sources and two microphones.
You can connect audio sources such as CD players, cassette players, VCRs, electronic instruments (drum
machines, keyboards etc.) to the line inputs.
When connecting turntables (phono inputs):
- Phono1 and line1 use the same input connectors; make sure the switch is set correctly!
- Phono2 and line3 use the same input connectors; make sure the switch is set correctly!
- When you're not using the connectors as phono inputs, set the switches to line position.
- NEVER connect a high level output audio device to a phono input!
- Connect ground wires from turntables to the ground pin on the mixing panel (3).
There are 2 microphone inputs: Mic1 through an XLR connector on the top plate, and Mic2 through a ¼"
(6.35mm) connector on the back plate. Both microphone channels have their own level control on the top plate.
Make sure the mixing panel is not connected to the mains when you're connecting audio equipment.
b) Outputs
In order to run the signal through a speaker system you need to connect the master outputs to a power amplifier.
The PROMIX400SF2 is equipped with 2 types of master output: RCA connectors and ¼" (6.35mm) connectors.
Make sure not to use both connections simultaneously.
The zone output is an extra master output. In order to run the signal through your second speaker system, you
need to connect the zone outputs (RCA connectors) to another power amplifier.
The record out stereo RCA connectors allow you to record the final mix. Connect any stereo recording device to
the record output.
The headphones connection allows you to monitor both the incoming sources before going into the mix and the
final mix. The PROMIX400SF requires headphones with a ¼" (6.35mm) plug.
You can also connect a 12V/3W lamp to the mixer provided it has a BNC type connector.
