5.4 MONITORING
The SX-ES64 audio mixer offers two independent stereo Monitoring sections and a so called Private Line
communication system.
5.4.1 Main Monitor source selector [ MON ]
The left most Monitor section (the Main Monitor) is dedicated to the sound engineer working on the mixer. It
allows the monitoring of the Master groups 1 to 4, to pre-listen to the input channels and the four returns as
well as a confidence return [EXT] if the optional connector is fitted.
The main monitor sources are the master groups 1-2 and 3-4. The selection is done with the [MON] push
buttons located under the master faders. While in stereo mode, the groups 1 and 3 are heard on the left
channel and groups 2 and 4 on the right channel of the main monitoring.
As soon as any [PFL] key is pressed, the PFL will automatically override the main monitoring selection and the
Yellow Led [PFL] on the secondary modulometer will turn on.
This main monitoring has two headphone outputs connected in parallel: the [PHONE1] output on a stereo jack
6.25 mm (1/4 ") located on the back panel and the [PHONE1] output on a mini-jack 3,5mm (1 / 8 ") located on
the front panel.
5.4.2 Monitor Mode selector [ EXT L R ST M MS MS/M]
The rotary switch defines the operating mode of the main monitor. Thus the selected source can be monitored
in the following ways
MS/M: the audio is MS decoded and then summed in Mono.
MS: decode an MS source for monitoring purposes only.
M: the selected stereo source is summed to mono. This is useful to easily check the mono
compatibility and detect a potential phase problem.
ST: the selected stereo source is monitored in stereo.
L: the left channel is monitored in mono on the both channels of the headphones.
R: the right channel is monitored in mono on the both channels of the headphones.
EXT: confidence monitoring of an additional stereo return if wired on the optional connector.
NOTE 1:
The MS decoder only affects the monitoring, not the main outputs. The decoder ration is fixed
to 50%. The M channel is sent in phase to both the left and right ears and the S channel is
sent in phase to the left ear and in reversed phase to the right ear.
NOTE 2: The [EXT] is only audible if the optional connector [OPTION[ is installed. (see the optional
connectors in the addendum chapter for the available connectors and their wiring).
5.4.3 Headphone level [ PHONE1 ]
This retractable potentiometer adjusts the level of the main monitor outputs between –infinite to +15dBu. As
both PHONE1 connectors are wired in parallel, the volume controls both outputs.
WARNING: The headphone amplifier of the SONOSAX SX-ES64 is quite powerful. It is highly
recommended to set the headphone level at a reasonable level to protect our precious ears.
5.4.4 Command switch [ COM ]
This push button allows sending announces on the secondary monitor output, but does not to the main
outputs. It is also heard as "Side Tone" in the main monitoring. There is no returned communication in this
mode.
5.4.5 Potentiometer [ MIC1 ]
The retractable knob [MIC1] adjusts the level of integrated electrets microphone. This microphone is used for
the SLATE, for the COM and for the private line PL1. The microphone is located under the PHONE2 jack.
