The line-level output signals are always aected by the setting of the front-panel audio
Modiers, with one exception - DIM only aects the line-level outputs when Variable
output level is selected.
Expansion Port
An internal expansion card (RM-HD1 or RM-HDE1) may be tted to the RM-4C8 to increase
the number of inputs and/or add to the available functions. Refer to Section 3 of this
handbook for details.
Remote Inputs and Outputs
A 15-way male D-type connector carries four open-collector status outputs, four logic-level
control inputs plus power and data lines for future use. The pin assignations are as follows:
Pin No. I/O Function
1 O Audio underlevel/fail alarm – latching open collector
9 I MUTE input – pull low to activate
2 O Audio overlevel alarm – latching open collector
10 I DIM input – pull low to activate
3 O Sustained phase error alarm – latching open collector
11 I Alarm Reset – pull low to activate
4 O AES/EBU lock output – non-latching open collector
12 I Not used
5 I Volume control voltage for future use
13 I Balance control voltage for future use
6 O Fused power for desktop remote control panel
14 - Ground
7 O Serial data transmit for future use
15 I Serial data receive for future use
8 O Serial clock for future use
Open-collector outputs are low (conducting) during normal operation. When an alarm
occurs they cease conducting and, with the exception of the AES/EBU lock output, remain
in that condition until the Alarm Reset input is asserted. Open-collector outputs are rated
at 50mA and 30V.
The Audio Overlevel alarm is triggered if either currently selected input Source exceeds
+12dBu for longer than 5 seconds.
