7.6 Monitoring
The SONOSAX SX-ST and SX-VT offers 3 identical and independent stereo Monitoring sections.
The left most Monitor section (the Main Monitor) is dedicated to the sound engineer working on the mixer. The
upper rotary switch selects the source for the phone output, the monitor output and the peak-meters. As soon
as a PFL/AFL button is depressed, the monitor outputs and the modulo-meters automatically switch over from
the monitor source to the selected P/A.
The lower rotary switch changes the listening mode ( mono –stereo – M/S ) of the selected source.
The two additional middle and right most monitor sections are available for independent remote monitoring and
communication purposes, both having an separate communication system ( Private Lines ). They can be used
to return different monitoring selections to e.g. the boom operator and the director/producer while on location
recording, or to a speaker cabin and to the video control room in broadcasting applications.
7.6.1 Monitor Source Selector
The upper three rotary switches select the source to be monitored:
1-2 to 7-8 : select Master Groups per pair 1 (Left) – 2 (Right) / 3 (Left) – 4 (Right) etc
AUX 1-2 : select Aux Sends 1 (Left) and 2 (Right)
AUX 3-4 : select Aux Sends 3 (Left) and 2 (Right)
7.6.2 Monitor Mode selector
The lower three rotary switches define the listening mode of the selected source:
RET : monitors the after fader stereo mix of the 8 Return tracks
ODD : the odd channel only of the selected stereo source is monitored in Mono
EVEN : the even channel only of the selected stereo source is monitored in Mono
ST : the selected source is monitored in stereo
M : the selected stereo source is summed in Mono to easily check the Mono compatibility and
to detect phase errors
MS: decode a MS signal for monitoring purposes.
The decoder is for monitoring purpose only and does not affect the main. The M-(left) channel is applied to both
L & R channels in phase and the S-(right) channel is applied in phase to the left channel and out of phase to the
right channel. The M/S decoder has a fixed ratio of 50%
NOTE: in Odd, Even and Mono modes, the signal is monitored in mono on both left and right sides.
7.6.3 Phones Level 1 to 3
Set the level of the corresponding monitor output (1 to 3) from - infinite (Mute) to +15 dBu
7.7 Communication and Private Lines
The SX-ST / SX-VT offers three independent communication systems: a main COM for general purposes and 2
full duplex Private Lines used for communication within the 2
nd and 3 rd monitoring sections.
COM : talk to all communications lines, incl. PL and PL2
PL1 : talk to second monitor section
PL2 : talk to third monitor section
An external electret or condenser microphone must be connected to the 5 pin binder COM connector. The
Talkback/Slate is using the same microphone. (see connectors section for pin assignment )
NOTE: The internal switch S3 selects the mic. powering voltage: 48V phantom or 6VDC for electret
7.7.1 Mic 1 to 3
Adjust the send level of the external Communication/Slate microphone that will be fed into the respective COM,
PL1 or PL2 lines. from - infinite (Mute) to +10 dB.
