Operating Manual - nX, nXe, and nXp Power Amplifiers
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
ne
software. See
section 8
in this manual for details on Ethernet communications.
6.2 Network Audio
- This is for an optional factory installed CobraNet
®
network audio module on
nXe and nXp models. Dante and AVB modules will also become available in the future. See
section 13
for details.
6.3 Standby
-
The STBY pin, when connected to the ground pin (G) as shown, will remotely
place the amp into standby mode. When the connection is opened, the amplifier returns to normal opera-
tion. The front panel power switch will flash when the amplifier is in standby.
6.4 Fault
- Four Fault pins are used with adjacent
ground (EG) and +5V pins for 5V logic outputs, and are
assigned in software <Device Options> to indicate an amplifier fault state. The
assignable fault conditions are overtemperature, rail voltage, and average power,
the same conditions that could place the amplifier into protect mode. Logic low
(0V) indicates fault condition. In the first example to the right, a remote red
LED is wired to F1 and +5V and turns on when a user-assigned fault condition
exists. F1 is normally high (+5V) but goes low (0V)
on fault. The second example uses a green LED wired
to F2 and EG to indicate no-fault, so the LED remains
on
unless
there is a fault. In the third example, a relay
circuit is driven by the F1 pin in order to switch on a
room or rack exhaust fan if the amplifier becomes se-
verely overheated. Maximum fault pin source current
is 20mA per pin. Maximum fault pin sink current is
200mA. Use an ex5V supply as shown if sink
current exceeds 200mA.
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
- These four pins (G, +18, OUT, IN) are for connecting a serial data remote control such as an
Ashly WR-5 or RD-8C. Ashly also offers an in-line converter called the
INA-1
which allows the data port to be used with third party RS-
232 controllers. A technical
RS-232 protocol document
is available on the Ashly website for third party developers. See more data remote
control application details in
section 10
.
6.7 AUX Outputs
- These Euroblock connectors provide preamp signals for driving other amplifiers. See the
block
diagram
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
- This is used for Ashly's two or four channel AES3 input and pass-through
module, available as a factory installed option on nXe and nXp models. See
section 12
for AES3 details.
