1. RCA Audio Connectors - Connect your CD player to your mixer from this line level output.
2. Digital Output - The format is Type 2, Form 1, also known as S/PDIF (Sony/Phillips Digital Interface
Format). To active Digital Output Mode, use the Program Menu. This allows digital audio information to
be sent.
3. Relay Connector- If you wish to use the relay function, plug in your 3.5mm stereo control cables into
here and then into your other CD player. The cable must have a stereo-style plug for the units to work
properly
4. Remote Start Connector – Use this connector to plug into your fader-start compatible mixer or remote
switch. This function is always active.
a. To use this connector for fader-start, connect the supplied fader-start cable to a fader-start
compatible mixer. Every time you move the crossfader on the mixer to the side that the unit is on,
it will start playing. When you move the fader away from that side, the unit will stop. Moving the
fader back will start playback again.
b. Foot switches can also be attached to this jack for creative mixing techniques and can be found in
most music shops. Connector plugs are often ¼", so a 1/8" adapter will be needed for connection.
There are also two types of footswitches that will work with this connector. The first is a typical,
on/off pushbutton switch and is generally used for switching channels on guitar amps. The second
type is a momentary footswitch, which is usually used for keyboard sustain pedals.
5. MIDI IN Connector – This port is for receiving MIDI (Musical Instrument Digital Interface) signals from
other MIDI devices such as CD players, keyboards, or drum machines.
6. MIDI OUT Connector – The port is for sending MIDI signals to other MIDI devices.
7. Voltage Selector - Set this switch to the voltage for your location.
8. IEC Power Plug Connector - Plug your supplied power cord in here.
