3 Operating Instruction
3 1 Connecting to the SX-R4+
A 3M MDR 26-pin pin-to-pin cable is required to interconnect the SX-RC8+ to the SX-
R4+. The SX-RC8+ is powered by the SX-R4+ and operates as soon as it is
connected to it.
3 2 Operating modes
The SX-R4+ menu SETUP/POT SETUP
allow to select 3 different operating
modes:
•Input gains
•Fader -60 to +12 dB
•Fader -60 to +24 dB
Input gains apply to AES input 1 to 8.
Fader mode have two different curves:
•-60 to +12 dB
•-60 to +24 dB
Both curves mute when fader is closed.
Faders must be assigned in the SX-R4+
MIX menu.
To assign a fader, press the ASSIGN
button.
First, choose the fader to be assigned
using the rotary encoder.
Then, push all track or track pair buttons
where the fader is to be assigned.
Push again the ASSIGN button to disable
fader assignation.
3 3 AES Breakout
The 4 TA3 connectors are used as AES breakout box, allowing easy connection of
AES sources such as digital wireless receivers.
The 4th TA3 connector (AES 7-8) is shared with the Slate/Com microphone AES
output.
SX-RC8+ User Manual /8
3 4 Slate/Com Microphone Control
The SX-RC8+ includes a microphone preamplifier with automatic gain control and Low
Frequency Cut filter. User can choose between the front panel mic or an external
headset connected to the Headset/Headphones 3. mm jack.
The SX-RC8+ configuration is integrated
into the SX-R4+ touch interface.
The configuration panel is located on
SETUP/SYSTEM/MISC/RC8+
•MIC SOURCE are two mutually
exclusive buttons where the
microphone source is selected
•LIMITER GAIN and
THRESHOLD allow user to
control the automatic gain control
•POT POS NOISE REDUC.
should be enabled in noisy
environment where the SX-R4+
detects faulty faders movements.
Any push-button of the SX-R4+ or SX-
RC8+ can be used to control the
slate/com.
Enter the menu SETUP/SYSTEM/PUSH
BUTTONS to modify push-buttons
assignation.
The label “SX-RC8+ MIC” correspond to
the slate/com microphone enable action.
3 5 Hirose Power Distribution
The power distributor on the left panel is fully independent and does not need any
power for the SX-RC8+ to operate. There are x Hirose 4 connectors connected as
following:
POWER
SMBUS
Note: there is no connection between the SX-R4+ power for the SX-RC8+ and that
power distribution.
The optional solder jumpers on pins 2 & 3 are dedicated for a System Management
Bus (SMBUS). By default, these jumpers are open.
