A PM-3R RHAON module has the same controls and indicators as the PF2-500R module on the previous page, but the layout is
different.
Appendix II (continued): RHAON Hardware Inputs, Outputs & Indicators
Primary & Secondary
Ethernet (CobraNet) Inputs
RJ-45 female
When both inputs are con-
nected, changeover to
Secondary is automatic if
Primary fails.
Primary Analog Input
XLR female
pin 1 chassis, pin 2 +, pin 3 -
Secondary Analog Input
Phoenix connector
pin 1 +, pin 2 -, pin 3 chassis
can be configured as a “priority over-
ride” input
Serial Digital Audio Input
Phoenix connector
pin 3 chassis, pin 4 +
AES3id format; automatically disables
all other inputs when selected
Looping Secondary Analog Output
Phoenix connector
pin 1 +, pin 2 -. pin 3 chassis
Fault Detect
Phoenix connector
pin 5 +, pin 6 -
Opto-isolated input used to monitor
the presence of an external wiring
loop; absence of a voltage is reported
to the DSP and transmitted to the
monitoring computer over the
Ethernet. Operates on 5 to 24 V DC
Fault Relay
Phoenix connector
pin 4 normally open
pin 5 wiper
pin 6 normally closed
NO / NC relay contacts used to report
a failure to an external monitoring
system; used mainly to trigger a fail-
ure indication on a hard-wired moni-
toring device; handles up to 0.5 Amps
at 24 V AC or DC.
Signal LED
Flickers when an audio sig-
nal of at least -30 dBu is
present at the primary analog
audio input.
Power LED
Glows when the amplifier is
On and not in Standby
Overdrive LED
Flashes red when the Primary
Analog Input preamplifier is being
over drive (input clipping)
Thermal LED
Lights to indicate that
an over-temperature
sensor has shut the
amplifier down
Input Pad & LED Indicator
On / Off 10 dBa pad for Primary Analog Input;
allows input signals of up to +24 dBu when
inserted manually or via computer control. Note:
this pad does not affect the +12 dBu maximum
input level of the Secondary Analog Input.
Push Button Volume Controls
Also functions as a manual
Standby/ON control; see Power
ON/Off Switch
Note: output level is also computer
controlled.
Mute Buttons
Note: Muting is also
computer controlled.
Protect LED
Lights to indicate
that protection limit-
ing is engaged.
Yellow LEDs flash when the
connector is active, glow
steadily when data is stream-
ing.
Green LEDs glow when con-
nected but inactive, turn
Orange to indicate a faulty
connection.
Looping Analog Output
XLR male
pin 1 chassis, pin 2 +, pin 3 -
NOTE: To prevent inadvertent operation the Mute, Volume Up & Volume Down, and Input Pad push buttons need to be pressed and held
down for several seconds before they activate.
