The R Series mixers use 3 different types of audio connectors: 3 pin XLR,
phone jacks and RCA phono
jacks. Some of these connections are balanced (3 conductor), unbalanced
(2 conductor), and some are stereo or have other multiple functions.
All microphone (mic) jacks are female XLR connectors
wired balanced with:
Pin 1 = ground, Pin 2 = hot (+) and Pin 3 = cold (-).
The ALT 3-4 outputs are wired with
Tip Ring Sleeve
jacks and are wired balanced with:
The Channel Insert Jacks are wired with
Tip Ring
Sleeve jacks and are wired unbalanced with:
The Stereo 2 Track Inputs and Outputs (TAPE IN / TAPE
OUT) are wired with RCA phono plugs and are wired
unbalanced with:
Tip = hot (+), Sleeve = ground (-).
The Headphone output is wired with
Tip Ring Sleeve jack and is wired as follows:
It is not recommended to use unbalanced microphone
connections especially if Phantom Power is on. This
could damage the mixer and the microphones.
- Tip = hot (+), Ring = cold (-), Sleeve = ground.
- Tip = Return (+), Ring = Send (+), Sleeve = ground
(-). These jacks can also be used as direct outputs for
direct-to-multi-track recording.
- Tip = Left, Ring = Right, Sleeve = ground.
