LD Systems ZONE 423 - Manual (Page 8)

connectionS, ConTRoLS, AnD InDICAToRS:
18 MASTeR eQ MID
Equalizer mid band for the MASTER channel.
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.
19 MASTeR eQ LoW
Equalizer low band for the MASTER channel. 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.
20 zone LeVeL
Volume control for the ZONE channel.
21 zone SoURCe
Selection of the signal source to be connected
to the zone output. Alternatively, one of the input
channels 2 - 4 (IN 2 - 4), or a mix (MIX) can be
selected from all input channels.
22 LeVeL MeTeR
Level meter display with 2 x 10 LED segments
(left / right). Once the peak LED (PK) lights up, the
device is operating at the distortion limit. It is not
critical if the LED lights briefly at peak levels for the
incoming signal, however continuous illumination
should be avoided by reducing the volume.
23 MASTeR / zone SWITCH (WITH BUILT-In LeD)
When the switch is not pressed, the LEVEL METER
displays the level of the MASTER channel.
When the switch is pressed ,the LEVEL METER
displays the level of the ZONE channel and the
built-in LED is on.
24 HeADPHone oUTPUT
Headphone output with 6.3 mm stereo jack.
25 CUe VoLUMe
Headphone volume control Channels, for which
the CUE button is pressed (INPUT 1 - 4), can be
listened to on the headphones output regardless
of their volume control setting.
26 PWR
On/Off switch for the device with built-in LED.
27 IeC PoWeR SoCKeT WITH InTeGRAL FUSe
HoLDeR
IMPORTANT INFORMATION: BEFORE using this
equipment, make certain that the mains voltage of
your energy utility and the operating voltage of the
device match! Always replace the fuse only with a
fuse of the same type with the same rating (printed
on the rear panel)! If the fuse blows repeatedly,
please contact an authorised service centre.
28 eMeRGenCY InPUT
Symmetrical terminal block connector for an
acoustic emergency response system (terminal
block included). As soon as there is an audio
signal with line-level signals, all microphone and
line inputs are muted, and the emergency signal is
directly connected to the MASTER and ZONE line
outputs. The volume control on the MASTER and
ZONE channels are then inactive.
29 LeVeL eMeRGenCY InPUT
Adjust the volume of the emergency signal with a
suitable screwdriver.
30 ReC oUTPUT L/R
Unbalanced stereo line output on RCA connectors
(left / right). The signal from the REC output consists
of the sum of the signals of the inputs MIC 1 / 2 and
INPUT 1 - 4 and FOH. The output level is independent
of the setting of the volume control of the MASTER-
output; the signal is sourced before the EQ, therefore,
it remains unprocessed.
