8. Setting Up
8.1 Selecting Inputs
1) Mono channels accept mic or line inputs. If you are using the mic input,
make sure nothing is connected to the line input (and vice-versa).
Please note that mic inputs are many times more sensitive than line inputs!
◊
Do not connect mics with phantom power switched on. NEVER use
unbalanced mic cables with the phantom power switched on ever!
Shorting +48 V DC to earth can cause serious damage.

Shorting +48 V DC to earth can cause serious damage.
2) Stereo channels accept line level signals. Any stereo channel can be run in
mono simply by connecting into the left jack socket only.
◊
This feature is disabled if all line level in-/outputs from the SX3282 are
wired permanently to a patchbay (see section 9 “Patchbay”).

The stereo channels are suitable for a variety of line-level sources including
MIDI instruments, effects outputs, and tape returns from multitrack.
3) Stereo aux inputs are primarily designed for returning effects

units, though these too may be given over to multitrack returns or
MIDI instrument outputs.
8.2 Initializing Channels for Gain Setting
1) Set gain to minimum and all aux sends to “off” (fully counterclockwise).
2) Set EQ to flat (all knobs at 12 o’clock).
3) Where applicable, set LO CUT switch

on for most mics, off for signals with

4) Set Channel Mode to PFL (

8.3 Auditioning a Signal and Setting
Up a Channel
1) Make a typical noise, or roll the tape. There should now be some activity at
the main bargraph meters, indicating the PFL level.
2) Adjust the gain control
(1)
until transient peaks are regularly hitting +2 dB.
Continuous signals should not exceed 0 dB.
3) With FX units, MIDI instruments and multitrack tape recorders (pro +4 dBu,
semi-pro -10 dBV), it is important to match the operating level of the
desk to that of your machine. If you are not sure which level your external
equipment requires, try a 0 dB setting first. If the signal is too low, turn the
gain pot to the right.
