X2442USB

CD/TAPE

The CD/TAPE switch routes the signal from the CD/TAPE INPUT jacks to the level meter, the CONTROL ROOM OUT outputs and the PHONES jack—this is a simple way to check recorded signals via monitor speakers or headphones.

SUB 1-2 or SUB

The SUB 1-2switch routes subgroup 1-2 to the level meter, CONTROL ROOM OUT and phones.

SUB 3-4

The SUB 3-4switch performs a similar function for subgroup 3-4 (X2442USB only).

MAIN MIX

The MAIN MIX switch sends the main mix to the CONTROL ROOM OUT and the PHONES output as well as to the level meter.

PHONES/CTRL ROOM

Use this control to adjust the control room output level and the headphones volume.

CD/TAPE TO MAIN

When the CD/TAPE TO MAIN switch is depressed, the 2-track input is routed to the main mix and thus serves as an additional input for tape machines. You can also connect MIDI instruments or other signals here that do not require any further processing. At the same time, this switch disables the main mix to tape output link.

POWER

The blue POWER LED indicates that the device is switched on.

+48 V

The red “+48 V” LED lights up when phantom power is switched on. Phantom power is required to operate condenser microphones.

◊While phantom power is switched on, do not connect or disconnect microphones on the mixer (or the stagebox/wallbox). Connect any micro-phones before switching on phantom power. Additionally, monitor/PA speakers should be muted before you activate the phantom power supply. After switching on, wait approx. one minute before adjusting the input gain so that the system

has time to stabilize.

2.3.11 Level Meter

The high-precision level meters always give you an accurate display of signal level.

LEVEL SETTING:

When recording to digital recorders, the recorder’s meter should not go into overload. This is because, unlike analog recordings, it takes only slightly excessive levels to create unpleasant digital distortion.

When recording to analog, the VU meters of the recording machine should reach approx. +3 dB with low-frequency signals (e.g. kick drum). Due to their inertia, VU meters tend to display too low a signal level at frequencies above 1 kHz.

You should only drive instruments such as a Hi-Hat as far as -10 dB. Snare drums should be driven to approx. 0 dB.

◊The peak meters of your XENYX display level almost independent of frequency. A recording level of 0 dB is recommended for all types of signal.

MODE

The MODE switch determines whether the channels’ SOLO switch operates as PFL (Pre Fader Listen) or as solo (Solo In Place).

PFL (LEVEL SET)

To activate the PFL function, press the MODE switch. The PFL function should, as a rule, be used for level setting (GAIN). The signal is sourced pre-fader and assigned to the mono PFL bus. In “PFL” mode, only the left side of the peak meter is in operation. A PFL’d channel should be driven to the 0 dB mark of the VU meter.

SOLO (NORMAL)

When the MODE switch is not depressed, the stereo solo bus is active. Solo is actually short for “Solo In Place”. This is the customary method for listening to an individual signal or to a group of signals. As soon as a solo switch is pressed, all channels not solo selected are muted in th e monitor path (control room and phones). A channel’s position in the stereo image is maintained. The solo bus carries the output signals of the channel pan controls, the aux sends and the stereo line inputs. On the X2442USB all aux returns, and on the X1832USB only aux return 2 can be routed to the solo bus. The solo bus is, as a rule, taken post-fader.

◊The PAN control in the channel strip offers a constant power characteristic. This means that the signal is always at a constant level, irrespective of position in the stereo panorama. If the PAN control is moved fully left or right, the level in that channel increases by 4 dB. This ensures that, when set at the center of the stereo image, the audio signal does not appear louder. For this reason, with the solo function activated (Solo in Place), audio signals from channels with PAN controls that have not been moved fully left or right are displayed at a lower volume than in the PFL function.

As a rule, solo signals are monitored via the control room outputs and headphones jack and are displayed by the level meters. If a solo switch is pressed, the signals from the tape input, the subgroups and the main mix are cut from these outputs and the level meter.
