Behringer MX2442A manual Setting UP, Selecting Inputs, Initializing Channels for Gain Setting

EURODESK MX2442A

8. SETTING UP

8.1 Selecting Inputs

1)Mono channels accept mic or line level 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 ever use unbalanced mic cables with phantom power switched on! 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 it into the left jack socket only.

+This feature is disabled if all line level in-/outputs from the EURODESK are wired permanently to a 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 the LO CUT switch “on” for most mics, “off” for signals with desired low-frequency content.

4)Set CHANNEL MODE to PFL ( up).

5)Depress the SOLO switch .

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 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.

+A -10 dBV nominal operating level for an effects processor almost certainly means 0 dB on the unit’s input or output meter. If the FX processor has indication only for input level, ensure that the output gives comparable, i.e. “unity”, gain.

4)If EQ is adjusted at any time, repeat steps 8.3 1) & 2).

5)If an insert is used to patch in a compressor, gate, EQ etc., use the outboard processor’s bypass or effect off switch to A/B monitor the effected and bypassed signals, which should be level matched. (If the unit does not have a bypass switch or equivalent, you will have to keep connecting and disconnecting the device until you achieve unity gain.)

6)SOLO switch up. Move onto next channel.
