Bass Boost
This amp has an adjustable Bass Boost acts like a single-
band para-graphic equalizer on the subwoofer channel. Use
the Bass Boost control carefully. Increasing low-frequency
output puts tremendous demands on the speaker and
amplifier.
The BASS BOOST control determines how much boost is
applied to the signal and is adjustable from 0 to +12dB. The
BASS BOOST FREQ Hz control determines that frequency
around which the signal boost is provided and is adjustable
from 30 to 125Hz.
Bridging Mode
The X2 1100.5 features a master INPUT SELECT switch that
selects between five- and three-channel operation.
The left-most INPUT SELECT in the BRIDGED 3CH mode
sends the signal on CH1 to Channels 1 and 2 and the input
signal on CH2 to Channels 3 and 4. The crossovers and
controls for CH1-2 should be used to adjust these signals.
Input Select Switches
The X2 1100.5 features two additional INPUT SELECT
switches to help simplify installations and system
configuration where only one or two sets of speaker wires
or RCA's is available to connect to the amplifier or when you
want to use this amp in three-channel mode.
The INPUT SELECT switches on Channels 3 and 4 and
the SUB Channel can be used in lieu of RCA Interconnect
Y-Cables to route signals from Channels 1 and 2 to these
respective outputs.
Load Impedance
A unique feature of the X2 1100.5 is it's adjustable rail voltage
CH1
CH3
system. Each pair of channels includes a LOAD SELECT
switch.
Under 4Ω - Any speaker or combination of speakers with a
total combined impedance between 2 and 4 Ohms (not lower
than 2 Ohms) must use this position. Bridged loads down to
4 Ohms must use this position. The amplifier will make full
CH2
CH4
power at 2 Ohms Stereo (4 Ohms bridged).
Over 4Ω - Any speaker or combination of speakers with a
total combined impedance at or above 4 Ohms can use this position. The amplifier will make full power at 4 Ohms stereo
(8 Ohms bridged).
The SUB channel is designed to drive a 2-Ohm load. Higher impedances are acceptable, but will result in decreased
power production.
WARNING: This amplifier will not operate and could be damaged if used with the LOAD SELECT switches in the wrong
configuration. At no time can it be operated below 2 Ohms stereo or 4 Ohms when bridged.
