Behringer MX2442A manual Metering

EURODESK MX2442A

The configuration is 24 into 4 into 2. This means that there are 24 channel inputs in total (there are 16 mono and four stereo channels), assignable to four subgroup buses (plus the main mix) which in turn may be blended into the main mix stereo output. The subgroups (configurable as stereo pairs if required) are provided for connecting to a multitrack tape recorder, or for use as a mixing aid during mix-down or during a live concert. Every channel, and both stereo aux returns can access at least one of the four existing subgroups, or the main mix directly, via comprehensive routing matrices. Four out of six aux sends can be accessed simultaneously. Every single input channel can be routed in two ways to the aux send buses: two pre- and four post-, or six post-fader, for live or studio operating environments respectively.

Input channels

The first 16 input channels are mono, with a choice of balanced mic (XLR, +48 V phantom power switchable) or line (1/4" TRS) inputs, both with exceptional gain architecture. Inputs 17/18 to 23/24 are configured as stereo input channels, accepting all line level signals.

Every channel has MUTE, SOLO/PFL and comprehensive EQ. A high-quality 60 mm fader feeds the main mix and/or subgroup buses depending on the assign switch position. A constant-power channel PAN also selects between odd and even-numbered subgroup buses.

Subgroups

For ease and flexibility, four mono subgroups with PAN and SOLO functions are provided. Each has its own individual output, and each may also be assigned to the main mix.

Aux sends

The MX2442A provides six master aux send outputs, each with separate SOLO switch.

Stereo aux returns

In the mid-upper section you will find two stereo aux returns, each of them equipped with a SOLO switch, BALANCE and LEVEL controls.

Main mix outputs/additional features

The main mix output level is being controlled via a pair of high-quality 60 mm faders. The main section also includes assignable headphones or control room outputs. The monitor (or control room) outputs are independently adjustable in level, and the integral talkback mic is routable to 4 of the 6 aux buses, i.e. all possible pre-fader (cue) sends.

A BNC connector is provided for a gooseneck lamp for those dark winter’s night mixes.

Inserts

All mono channels, subgroups and the main mix have insert points for the connection of dynamics processors etc.

2.2 Metering

All input channels feature signal (- 20 dB) and overload LEDs, while the L and R output has a pair of 12 digit bargraph meters. The main mix (L/R) meters also have clip LEDs (+28/22 dB: balanced/unbalanced). Alternatively, the LEDs in the main section are used to display the mono PFL, stereo SOLO or the 2-track input (in general, what you hear is what you see).

+The master clip LEDs (+22 dBu) should never be allowed to illuminate. If they do, reduce either the main mix faders or the group(s) and/or channel fader(s), or (as a last resort) the channel input gain(s). Maybe it’s time to do a round of PFL metering.

+In SOLO/PFL mode a 0 dB meter reading matches an internal operating level of 0 dBu (0.775 V). However, when looking at the mix, 0 dB is referenced to +4 dBu, the 2-track operating level. I.e. if only one signal is present in the main mix bus, soloing that signal will cause the meter reading to increase by +4 dB.
