15 – FUSE CARRIER
Holds the AC mains fuse.
16 – AC MAINS CONNECTOR
IEC type power cord attaches here.
17 – SEQUENCE CONNECTOR
Used for sequencing power to multiple amps. (See page 11)
18, 20 & 22 – SPEAKER OUTPUTS
A set of three 4-conductor Neutrik
®
Speakon
®
NL4 connectors to
connect the amplifier to the speakers.
18 - CHANNEL TWO
provides the output of channel two only, on pins 1+/1-.
20 - BRIDGED MONO
uses the output of both channels to create a single channel with
twice the power. The output is provided on both pins 1+/1- and 2+/2- of the Speakon
®
,
allowing the use of all four conductors to lower the cable resistance. This output should only
be used when the Mono switch is enabled.
22 - CHANNEL ONE
actually provides output for channel one AND channel two using a
single 4-conductor cable.
Channel one output is present on pins 1+/1- of the Speakon
®
, and channel two output is
present on pins 2+/2-.
19 & 21 - SPEAKER OUTPUTS
Two pairs of five-way binding posts to connect the amplifier to the
speakers.
19 - CHANNEL TWO
provides the output of channel two across the red(+) post and the
black(-) post.
19 & 21 - BRIDGED MONO
uses the output of both channels to create a single channel with
twice the power. The output is provided across the CH 2 red(+) post and the CH 1 black(-)
post. This output should only be used when the Mono switch is enabled.
22 - CHANNEL ONE
provides the output of channel two across the red(+) post and the
black(-) post
23 & 32 – BALANCED AUDIO INPUTS
Neutrik
®
Combo connectors which accept male XLR, TS and TRS 1/4´´
phone plugs. By default, XLR pin 2 is hot and Tip is hot. Polarity of the
XLR can be reversed with jumper settings inside the amp. (See page 9)
24 & 31 - BALANCED AUDIO INPUTS
Euro-type connectors used for balanced or unbalanced signals.
25 & 30 – GROUND LIFT SWITCHES
Switches for each channel that disconnect Ground pin of the input
connectors from chassis ground. Used to eliminate ground loop
conditions that cause hum.
26 & 29 – GROUND LIFT STATUS LEDS
These are separate indicators for each channel which light up when the
Ground Lift switches are enabled.
27 – MONO SWITCH
When the switch is ‘in’, the amp is set to Mono mode. Mono operation
causes the signal connected to the channel Two input to drive both
channels. The channel One input is disabled in Mono mode.
28 – MONO STATUS LED
This indicator will light when the Mono switch is engaged.
33 – STANDARD INPUT MODULE
This replaceable module handles the input signals. Available upgrade
modules include a 4X2 mixer, single/dual zone paging modules, an
expanded mic / line level input module, a computer control and
monitoring module, and a DSP module with EQ, crossover, limiter, and
delay.
