1.2 Rear panel
22 Stereo replay input (phono, unbal.) for connecting
the replay output of the recorder connected to the
jacks “RECORD” or another unit with line output
level (e.g. CD player)
23 Insert jacks for inserting a unit for sound process-
ing (e.g. graphic equalizer) into the left and right
channels of the master output; for connection see
chapter 5.2
Piug connections:
Tip = send (output)
Ring = return (input)
Body = ground
24 Recessed switch for connection of the 48V phant-
om power for all jacks “MIC” of the mono channels;
required for connecting capacitor or electret micro-
phones operating at a 48V phantom power.
Caution!
To prevent switching noise, only actuate the switch
with the mixer switched off. Please also observe the
safety note in position 28!
25 Mono outputs (6.3 mm jack, unbal.) respectively for
the send way “AUX” and the send way “MON”
26 Stereo input (6.3 mm jack, bal.) for connecting an
additional unit with the output level.
Note: In case of a mono unit, only use the upper
jack “AUX-IN-LEFT”. The signal is then inter-
nally switched to the right and left channels.
27 Stereo inputs (6.3 mm jack, bal.) for stereo channels
for connecting stereo units with line output level.
Note: In case of a mono unit, only use the upper jack
“LINE-LEFT”. The signal is then internally swi-
tched to the right and left channels.
28 Microphone inputs (XLR, bal) for the mono channels.
Caution!
With the phantom power switched on (yellow LED
“PHANTOM POWER + 48V” lights up), all micropho-
ne inputs of the mono channels are supplied with a
48V phantom power.
In this case, never connect any unbalanced microp-
hones as they might be damaged.
Note: The phantom power can be switched off inter-
nally for individual mono channels or switched
on for individual stereo channels (to be perfor-
med by skilled personnel only!).
See chapter 4.1.
29 Mono inputs (6.3 mm jack, bal.) for the channels for
connecting mono units with line output level.
30 Insert jacks for inserting units for sound processing
(e.g. compressor) into the mono channels.
For connection see chapter 5.2.
Plug connections:
Tip = send (output)
Ring = return (input)
Body = ground
31 Direct outputs (6.3 mm jack, unbal.) for the mono
channels this is where the processed channel
Signals are available after their faders.
They can be fed e.g. to a multi track recorder or to a
second mixer.
Note: The signal take-off point can be modified inter-
nally to pre-equalizer separately for each indi-
vidual channel (to be performed by skilled pe-
rsonnel only!). See chapter 4.3.
32 5 pin male plug connector is fitted to the diamond
24-4-2DX & 16-4-2DX & EP7 is fitted with 5 pin fe-
male plug connector.

20 Stereo master output (XLR, bal.) for connecting the
power amplifier of the PA system.
21 Stereo recording output (phono, unbal.) for conne-
cting the input of a recorder, the recording level is
adjusted with the control “RECORD LEVEL” and it
additionally depends on the position of the master
faders.
13 Level control for the recording output “RECORD”
14 Master controls respectively for the send way
“AUX” and the send way “MON”
15 Level control for the input “PLAYBACK”
16 Level control for headphones connected to the
jack below.
17 6.3 mm jack for connecting stereo headphones
(Minimum impedance)
a) For monitoring the master signal at the jacks
“MAIN MIX OUTPUT” if none of the PFL buttons
has been pressed or
b) For pre-fader listening to the input channels
selected with the PFL buttons
18 Level control for the additional stereo line input
“AUX-IN”
19 Master faders (”L” (left)/”R” (right) for level adjustm-
ent of the stereo master signal at the jacks
