Behringer MX2442A manual Stereo Input Channels

EURODESK MX2442A

4. STEREO INPUT CHANNELS

The stereo input channel consists of almonst the same controls as the mono input channel except for the input, the EQ and the BALANCE control. For further information on the remaining controls, please refer to section 3 “MONO INPUT CHANNELS”.

Every stereo channel has two line level inputs on 1/4" jacks. If only the left input is used, it will work as mono channel.

+This feature is disabled, if the inputs and outputs of the EURODESK are wired permanently to a patchbay.

The channel input sensitivity is variable between +/- 20 dB by adjusting GAIN , enabling a perfect match with all common line-level sources including multitrack tape outputs, MIDI and other electronic instruments and effects units, all of which are normally designed to operate at either -10 dBV or +4 dBu.

4.1 Input Level Setting

Input level setting works in the same ways as on mono channels (see section 3.1).

4.2 Equalizer

All stereo input channels are fitted with four-band, fixed-frequency EQ. Bands 1 and 4 are shelving, while bands

2 and 3 have a peaking response, with their Q set at 2 octaves.The upper and lower shelving controls

have their turnover frequencies fixed at 12 kHz and 80 Hz, whereas the midrange controls and have their bell center frequencies set at 3 kHz and 500 Hz. All bands have up to 15 dB of cut and boost, with a center detent for “off”.

+A stereo equalizer is generally preferable to using two mono equalizers when EQ-ing a stereo signal, as often discrepancies between left and right settings can occur.

4.3 Aux Sends

These are the same as for mono channels (see section 3.3). Please note that first the stereo signal is turned into a mono sum before entering aux send.

4.4 Routing & Muting

The only difference here from the mono channel described in 3.4 is in the substitution of the pan control by the BALANCE control ( ).

As long as a channel is run in mono, there is no difference at all.

In stereo operation however, this control functions as a BALANCE control , determining the relative balance of the left and right channel signals which are being sent to the left and right main mix, or odd and even subgroup buses. For example, with the BALANCE control turned fully clockwise, only the right portion of the channel’s stereo signal will be routed to the selected buses, the left portion is faded out.
