1. INSTRUMENT 1 AND INSTRUMENT 2 INPUTS
These unbalanced inputs accept 1/4” connectors and support instrument
level sources (including guitars). Note that when the Instrument 1 input

Instrument 2 and Mic/Line 2 inputs: when the Instrument is connected, the
Mic/Line is disabled.

3. POWER JACK

4. USB PORT
The USB Port is used to connect the 42 to your computer. A standard USB
cable is included. The 42 is only compatible with USB 2.0.
5. MIDI IN AND OUT
The MIDI jacks provide MIDI input and MIDI output to and from your
computer. Connect your MIDI keyboards, sound modules, and external
controllers here.
6. S/PDIF IN AND OUT
The S/PDIF in and out ports are unbalanced phono (RCA) connectors that
transmit and receive either a 16-bit or 24-bit two-channel audio stream.
S/PDIF ports may be found on many professional and consumer CD and
digital audio recorders. It is recommended to use 75-Ohm coaxial cable for
S/PDIF transfers and keep the cable length to a maximum of 10 meters to
minimize interference and data dropout.
7. MAIN OUTPUTS
These outputs support balanced TRS or unbalanced TS ¼” connections.
These outputs can be connected to a mixing board, power amplifier,
powered studio monitors, recorder, or another line level input. When
connecting to other balanced equipment, use balanced cables for best
performance.
