Overview
Chapter 1
The Sony MXP-310 is a multipurpose audio mixer that features all the
essential functions demanded by professional audio processing.
12 channel inputs: six mono (MIC/LINE selectable) and six stereo
(line) with many adjustment possibilities
You can adjust each input signal level independently to suit the output
signal from connected equipment and provide high-quality mixing through
the MXP-310’s low-cut filter and four-band equalizers (three of the band
equalizers are equipped with stereo inputs).
You can place each input sound image at any desired spot between the left
and right channels with the PAN POT function.
+48 V DC selectable microphone powering
On the mono input modules, the built-in power supply circuits supply 48 V
DC to the connected phantom-powered microphones (those designed for
use with an external power supply.)
Two stereo effect returns
Assignable to each master output
Console table mount
The MXP-310 can easily be placed on a control console table with the
MXBK-TK390 table kit (not supplied).
