IMPORTANT
: When the amplifier is in MUTE, the PROTECT LED will be also lit to
show that the amplifier is disabled. Also when the system is waking up from the
STANDBY mode, the PROTECT led will be lit for a few seconds. Under these
circumstances the PROTECT LED is reporting that the amplifier is disabled, but not a
fault condition.
D) SIGNAL INPUT LEDS
: Monitor the signal arriving at the module input.

Input:
Signal is present at the input. Nominal input level is +8dBu (2Vrms).

OVLD:
The input signal exceeds +14dBu (4Vrms), so it will be compressed.
Avoid the continuous lighting of this led in order to preserve the dynamic range
of the audio signal.
E) OUPUT LEDS
: Show the amplifier output level

-24dB:
The amplifier is delivering output power at -24dB of its maximum power

-12dB:
The amplifier is delivering output power at -12dB of its maximum power

Clip:
The amplifier is delivering its maximum output power
The connection panel has the following parts:
F) NETWORK:
Computer connection through Ethernet protocol. Two 8-pin RJ45 /
EtherCon® compatible connectors with an internal switch allow the connection of
several units in daisy-chain. Please refer to Master Audio DSPStudio Quick Installation
Guide for more information on the remote connection.
G) BALANCED INPUT/LINK
:
XLR-3 Female balanced signal connector for signal input.
XLR-3 Male connector for parallel connection of various cabinets with the same input
signal.
IMPORTANT:
Please always use balanced microphone cable with the following pin
assignment:
1= Shield (Ground) 2= Live (+) 3= Return (-)
H) AC INPUT/OVERVOLTAGE PROTECTION:
These leds show the status of the
AC mains supply.

ON:
(Blue) When lit, the equipment is ON and the AC input level is within the
permitted range (200 to 250 VAC).

STANDBY:
(Orange) This led is lit when the equipment is sensing the AC
voltage at the input. At power-up this led will lit for a second while the systems
checks for the input voltage.

OVERVOLTAGE PROTECTION:
(Red) When activated, the AC voltage is
permanently out of the permitted range of the equipment (>250VAC), so it will
remain under protection until this condition is solved. Revise your connections
and mains power installation and consider that other equipment connected to
this line may have been damaged.
I) AC MAINS INPUT/LINK:
Mains supply connection via PowerCon.

Blue connector for AC in.

Grey connector to feed other units in parallel. Linking up to 2 units of X-218W is
possible, provided that a quality cable of a minimum section of 3x2,5mm2 is
used. Connecting more than 2 units in parallel may lead to a voltage drop in the
cable that will reduce the equipment performance.
