5.4.6 Secondary Monitor selector [ 1-2 3-4 RET EXT - ]
The section of the secondary monitor is used generally for remote monitoring; it is totally separate from the
main monitoring. This section is typically used as an alternate monitor for a video control room or a speaker
cabin in a broadcast application, or for the boom operator and/or the director while a recording on location. It
provides with an off-line full duplex communication system (Private Line).
The output of the secondary monitor is available simultaneously on the XLR-6M [COM / PL] on the rear panel
and on the [PHONE2] mini-jack output on the front panel. Both outputs are internally wired in parallel.
The monitor selector let choose from four different sources to be listened in mono if the selector is in the lower
section "M" or in stereo if the selector is in the upper section "ST". The monitoring is muted in the intermediate
position.
1-2: monitors masters 1 and 2, either in mono or in stereo
3-4: monitors masters 3 and 4, either in mono or in stereo
RET: monitors the return mix bus after the fader (AFL).
EXT: confidence monitoring of an additional stereo return if wired on the optional connector
NOTE: The [EXT] is only audible if the optional connector [OPTION[ is installed. (see the chapter
optional connectors and the addendum for the available connectors and their wiring).
5.4.7 Headphone level [ PHONE2 ]
This retractable potentiometer adjusts the level of the secondary monitor outputs between –infinite to +15dBu.
As both PHONE2 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.
5.4.8 Touche [ PL1 ]
This push button activates the communication in full duplex mode over the private line PL1.
The communication's send is using the integrated microphone and is controlled by the potentiometer [MIC1].
For duplex communication, an external microphone must be connected for the returned communication to the
XLR-6M [COM / PL] connector. Its volume is controlled by potentiometer [MIC2]. Note that this connection is
permanently powered with a 48V phantom voltage.
PL1 communication can be remotely activated by bridging via a switch the ground (Gnd) of the external
microphone line and the ground of the secondary monitor connector XLR6-M [COM / PL]
A small boom box with bet clip is available under reference SX 022260.
5.4.9 Potentiomètre [ MIC2 ]
The retractable potentiometer [MIC2] controls the volume of the external microphone being used for the full
duplex communication over the private line PL1. It must be connected to the XLR-6M [COM/PL].
WARNING: The microphone input for the return communication on the connector XLR6-M [COM / PL] is
permanently powered with 48V Phantom voltage.
5.4.10 Headphone outputs [ PHONE1 et PHONE 2 ]
These mini-jack 3,5mm ( 1/8" ) headphone outputs allow any kind of stereo or mono headphone having an
impedance between 35 and 400 ohms.
The [PHONE1] output is wired in parallel with the main monitoring output on the jack 6,35 ( 1/4" ). The
[PHONE2] is wired in parallel with the secondary monitor output on the XLR6-M. Thus, it is possible to
connect two headphones on each of the two monitoring outputs.
Headphone outs are mini-jack stereo 3,5mm ( 1/8" ) where:
Sleeve = Gnd / Ring = Right channel / Tip = Left channel
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.
