Mono Channels - LD LDVIBZ24DC User Manual

12
Unbalanced mono line outputs with 6.3 mm jack sockets to control an external effects device (POST Fader), or
an active stage monitor (PRE Fader).
13
3-pin 6.3 mm jack sockets for inserting an external signal processing device (Compressor, Gate, etc.) in the
14
corresponding channels 1 to 8. A special insert cable is required for the connection (Y-cable, 1 x stereo jack to
2 x mono jack or XLR). The assignment is as follows: TIP = Send, RING = Return, SLEEVE = Masse.

MONO CHANNELS 1 - 16

15
14
Balanced inputs of the channels 1 to 16 with 3-pin XLR sockets for connecting microphones. A 48 V phantom
power supply is available for operating condenser microphones, and it can be switched centrally to the XLR
sockets (N° 3). Please set the Gain controller (N 18) to minimum (left stop) before connecting or
disconnecting a microphone; and switch on the phantom power only after connecting the microphone, or off
before disconnecting.
16 17
15
Balanced inputs of the mono channels 1 to 16 with 6.3 mm jack to connect a source device with a line level.
Please set the Gain controller (N 18) to minimum (left stop) before connecting or disconnecting jack cables.
16
18
Low cut filter for suppressing low-frequency signals. Especially with voice and singing transmissions, an
activated LOW CUT feature (switch in the down position) can reduce disruptive bass frequencies and thus
increase speech intelligibility. The cut-off frequency is 95 Hz.

19
Using this pressure switch, the inputs of channels 1 to 4 can be switched separately to high impedance
(press switch down for activation). Thus, using instrument channels for guitars or basses is possible.
18
Adjusting the gain of the microphone input from 0 to 50 dB, or the sensitivity of the line input from +15 dBu
to -35 dBu. Adjust the Gain controller so that the Clip LED of the corresponding channel only lights up briefly
21
when signal peaks occur. Avoid the permanent lighting of the Clip LED by reducing the input gain or input
sensitivity.
19
22
Sliding compressor controller for channels 1 to 8. Depending on the setting, the signal is more or less
compressed, i.e., the dynamics of the signal is restricted (controller to the left stop = compressor is disabled,
controller to the right stop = maximum compression). The level loss caused by the increasingly stronger
compression is automatically compensated by the compressor unit. The use of the compressor can provide
for an improved clarity of a singing voice in the mix.
23
20
As soon as the compressor is active, the display LED lights up.
24
21
Equalizer high band for channels 1 to 16 (12 kHz, +/-15 dB). When turned to the left, levels are lowered, when
turned to the right, they are raised. In the centre position (resting point), the equalizer is inactive.
