Channel Inputs and Outputs
Each of the 16 channel modules on the Studio 32 contains an XLR balanced MIC IN
connector, a 1/4" TRS balanced LINE IN jack, a 1/4" TRS balanced TAPE IN jack, a
balanced 1/4" TRS DIRECT OUT jack, and a 1/4" TRS INSERT jack. Here are more
detailed descriptions of each of these, and what they should be connected to.
Mic Inputs
The MIC IN of each channel is a standard female XLR-3 connector. The cable
wiring is illustrated below:

The MIC Input is designed to accept a wide range of balanced or unbalanced low
impedance input signals. Each input can provide the +48 volts necessary for
phantom-powered microphones on pins 2 and 3; this may be turned on and off with
the PHANTOM switch.
Avoid connecting a mic while the fader is up and phantom power is on.
Do not connect a microphone and a line input to the same channel.
Line Inputs
The LINE IN of each channel is a 1/4" jack which will accept balanced or
unbalanced line-level sources.
“Line level” means that signals are typically in the 1/3 of a volt to 2-volt range,
such as the output of synthesizers, keyboards, CD players, etc. This is in contrast to
the much lower levels usually output by microphones (measured in millivolts).

Unlike the low impedance microphone input, this connection provides a high
impedance (>10kΩ) to the input signal, enabling most instruments to be plugged
straight in without direct boxes or external preamplification. While the output of
a standard synthesizer (or other equipment) can be plugged in using a 2-conductor
