Rear Panel Features (Nxe Series); Ethernet Port; Network Audio Module Option; Standby Contact Closure - Ashly nX8004 Operating Manual

 6 nXe SERIES REAR PANEL FEATURES
The following nXe features are in addition to standard features found in nX series amplifiers:

6.1 Ethernet Port

- This RJ-45 connector offers Ethernet control and monitoring of the amplifier using Protea
See section 8 in this manual for details on Ethernet communications.
6.2 Network Audio
on nXe and nXp models. See

6.3 Standby Contact Closure

will remotely place the amp into standby mode. When the connection is opened, the amplifier returns to
normal operation. The front panel power switch will flash when the amplifier is in standby.
6.4 Fault Pins
6.3 Standby Circuit
output channel. Fault pins are used to drive external LEDs or connect
with equipment that can remotely monitor or respond to a serious ampli-
fier problem. A fault is indicated by the loss of a normally present "heartbeat" signal, where the
output continuously toggles between 0V and +5V at a 1Hz rate.
The normal heartbeat signal on each fault pin is interrupted
whenever a fault condition prevents normal function of that
channel while the amplifier is either powered on or in the
standby state. Fault conditions include loss of AC mains
voltage, excessive internal temperature, power supply
voltage out of range, DC on output, or microprocessor
malfunction. A fault pin output can directly drive an LED
as shown in the circuit illustration to the right.
If a fault occurs, fault pin output may be latched <Low> or
<High> depending on the type of fault or state of the output
at the moment the fault occurred. A fail-safe fault detection
circuit should monitor and respond only to the loss of the
1Hz heartbeat signal.
6.5 Preset
- Each pin (P1 through P4) can be connected to the adjacent ground pin (G) via Ashly's WR-2 remote or other contact closure
to recall a stored preset or sub preset from the amplifier. Preset pins 1-4 correspond directly to amplifier presets 01 - 04.

6.6 Serial Data Connector

WR-5 or RD-8C. Ashly also offers an in-line converter called the
trollers. A technical RS-232 protocol document
application details in section 10.

6.7 AUX Outputs

- These Euroblock connectors provide preamp signals for driving other amplifiers. See the
on page 59 for the differences between two and four channel amplifier AUX outputs. AUX outputs are pseudo-balanced, meaning
they use single ended signal with balanced impedance, and can be wire balanced or unbalanced.

6.8 AES3 Digital Audio I/O Option

available as a factory installed option on nXe and nXp models. See
Operating Manual - nX, nXe, and nXp Power Amplifiers
- This is for an optional factory installed CobraNet or Dante network audio module

- A fault logic output pin is available for each amplifier
- These four pins (G, +18, OUT, IN) are for connecting a serial data remote control such as an Ashly
