To connect a RHAON network, you first make hardware connections, and then (if you are using CobraNet for digital audio distribution)
assign signal routing using RHAON software. Since all Ethernet connections are made using RJ45 connectors and standard Ethernet
hardware, the network infrastructure is cost-effective and easy to install. You can also connect Serial Digital (AES3id aka AES/EBU) and
analog audio to a RHAON-Empowered loudspeaker, as well as Fault Detect and Fault Relay lines. A typical RHAON Input Panel is
shown below.
Appendix II: RHAON Hardware Inputs, Outputs & Indicators
The RHAON input panel shown above is a PF2-500R. Other input panels include the same connections and controls in different layouts.
Primary & Secondary
Ethernet (CobraNet) Inputs
RJ-45 female
When both are connected, changeover to
Secondary is automatic if Primary fails.
Yellow LED flashes when the connector
is active, glow steadily when data is
streaming. Green LEDs glow when connected
but inactive, turn Orange to indicate a faulty
connection.
Primary Analog Input
XLR female
pin 1 chassis, pin 2 +, pin 3 -
Looping Analog Output
XLR male
pin 1 chassis, pin 2 +, pin 3 -
AC Power ON/Off
NOT under computer control by RHAON.
RHAON software can put the amplifier in Standby, but a remote computer cannot
disconnect the AC power. To toggle between On and Standby manually, hold
both the Up & Down Volume push buttons down for approximately 3 seconds.
Secondary Analog Input
Phoenix connector
pin 1 +, pin 2 -, pin 3 chassis
can be configured as a “priority override”
input
Serial Digital Audio Input
Phoenix connector
pin 3 chassis, pin 4 +
AES3id format; automatically disables all
other inputs when in use
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 pres-
ence of an external wiring loop; absence of a
voltage is reported to the DSP and transmit-
ted to the monitoring computer over the
Ethernet. Operates on up to 24 V DC
Fault Relay
Phoenix connector
pin 4 normally open
pin 5 swing blade
pin 6 normally closed)
NO / NC relay contacts used to report a fail-
ure to an external monitoring system; used
mainly to trigger a failure indication on a
hard-wired monitoring device; handles up to
0.5 Amps at 24 V , AC or DC.
Signal LED
Flickers when an audio signal 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 down the amplifier.
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 function as a manual Standby/ON con-
trol; see Power ON/Off Switch
Note: output level is also computer controlled
Mute Buttons
Turn Loudspeaker muting on and off; muting
is also computer controlled
AC Line Fuse
IEC Power Connector
Voltage Selector
Not on all Models
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.
