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 sensivity from –10dBu to +25dBu to reach a digital
recording level of 0dBFS
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 connecotr and a stereo Mini-
Jack wired in parallel. The mini-jack can also accommodate a headphone. (minimum impedance is 30ohms )
The retractable potentiometer adjusts the output Level between from –10dBu to +25dBu for 0dBFS.
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 18VDC
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 ou negative / Pin4 = +V DC or positive; the voltage range is 6 to 18 Volts DC
The Hirose 4 pin male cable connector is available by SONOSAX or by your local dealer under references:
