4.2.2 Stereo/dual-channel Line Input [ STEREO IN ]
This unbalanced stereo/dual-channel Line Input is provided to connect any external device to the SX-R4 such
as for example a SONOSAX SX-M32 or SX42 mixer, receivers of wireless systems or any other external
analog source.
The input signal corresponds to the Input channels 5 (Left) & 6 (Right) in the routing matrix system. The
retractable potentiometer adjusts the input sensitivity from –10 dBu to +25 dBu to reach a digital recording
level of 0 dBFS.
The [STEREO IN] connector is a mini-XLR TA-3 male where:
Pin1 = GND, Pin2 = Left channel, Pin3 = Right channel.
4.2.3 Subsidiary Stereo Output [ SUB OUT ]
This unbalanced stereo/dual-channel Line Output is provided to send a rough pre-mix to any external analog
device such as for example a video camera, a transmitter or an alternative monitoring system.
This stereo/dual-channel [SUB OUT] is totally independent of the [PHONES] output and has its own
matrixing/mixing system. The combination of tracks and their routing to the Left or Right channel is similar to
the Monitoring system but is defined in the [LINE OUT] menu. It offers the same facilities including the Mono
summing and the M/S decoding (see chapter 5.2.4).
For ease of connections, this Line output is provided simultaneously on a TA-3 connector and a stereo Mini-
Jack wired in parallel. The mini-jack can also accommodate a headphone (minimum impedance is 30 ohms).
The retractable potentiometer adjusts the output Level between from –10 dBu to +25 dBu for 0 dBFS.
The [SUB OUT] connector is a mini-XLR TA-3 male where:
Pin1 = GND, Pin2 = Left channel, Pin3 = Right channel.
4.2.4 External Sync [ SYNC IN ]
This SMA connector provides an input for an external WordClock or a Video reference. Thus, it allows
synchronizing the A/D Converters of the analog inputs 1 to 6 on an external reference. The selection of the
synchronization signal is achieved in the contextual menu (see chapter 5.2.2).
4.2.5 Sync Out [ WCKL OUT ]
This SMA connector delivers a WordClock sync signal. Its frequency depends either of the selected sample
frequency selected in the in the "Sampling settings" menu, or of the incoming frequency of the [SYNC IN] if it
is a valid WordClock, or of the sample frequency of the incoming AES input if a valid AES input in connected
on channel 7/8 and properly routed in the matrix system.
4.2.6 External DC input [ DC IN ]
The SONOSAX SX-R4 can be powered by means of an external DC supply, either a main adapter or an
external high capacity battery bank. The voltage must be regulated between 6 to 18V DC.
The average power consumption of the recorder is around 4 Watts. This represents a DC current of 330mA
under a supply voltage of 12Volts. However, while turning On the recorder the inrush current may reach 2A,
therefore make sure that your external DC supply can sustain this peak of current .
To ensure optimal performances we recommend you to use the optional main adapter available by your local
dealer.
the DC IN connector is a Hirose 4 pin female :
Pin 1 = GND or negative / Pin4 = +VDC or positive (6-18 Volts DC)
The Hirose 4 pin male cable connector is available by SONOSAX or by your local dealer under references:
SONOSAX part nr SX860217 or Hirose HR10-7P-4P.
