Amplification G41 Powered Crossover/Amplifier recommended
Crossover cards designed for the G41 Powered Crossover/Amplifier
(see below) are supplied with each loudspeaker. These
feature premium quality Burr-Brown operational
amplifiers and four-layer printed circuit boards.
The G41 powers 200 and 300 Series
installation loudspeakers in Remote
Active mode. It features active crossovers,
switched balanced and unbalanced
inputs, and employs the same low-
feedback topology as Meridian’s
G55/56/57 amplifiers, which was
developed from that used in the flagship
DSP8000.
Eight channels of approximately100W/8Ω
(180W/4Ω) RMS amplification are
provided, grouped into four pairs, each
providing bass and tweeter outputs from
a full-range input.
The fourth channel pair can also be
configured as two full-range amplifiers
for driving a pair of passive loudspeakers,
eg for surrounds. To do this, the right-
hand modular crossover card is removed
and replaced by one providing additional
full-range unbalanced inputs.
Replacement labels identify the
reconfigured output terminals (see rear
panel illustration below).
The crossover modules take the form of
cards which can be inserted at the time
of installation to configure the unit for
the speakers in use, and an appropriate
card is supplied with each loudspeaker.
Modules are available for the 320, 330
and 350, and each module includes a
pair of LEDs that confirm the positive
and negative power-rails are operative
and identifies the crossover installed by
means of the colour combination. 200
Series units can use the crossover or can
be driven in passive configuration with
the fourth amplifier pair configured for
two channels of full-range operation.
Thermal, short-circuit and DC fault
protection circuitry is included. The G41
has soft start, fan output and trigger
input.
A unique feature of the G41 is a cable-
length compensation switch. The
amplifiers have a negative impedance to
cancel out cable effects. This dramatically
improves performance, tightening the
bass response and giving significantly
improved control and punch. Two switch-
selectable settings are provided, one
for cables under 10m and the other for
cables over 10m in length. A separate
rear-panel switch is provided for each
pair of amplifiers.
Meridian Remote Active loudspeakers
may also be driven by the C51 rack-
mount unit, part of our C Series custom
installation range. A separate data sheet
is available on request.

Specify in-wall or flush-mount configuration (see dimensioned drawings inside). Rough-in boxes available separately.
*The 320 units may optionally be ceiling-mounted; the 330 and 350 are not suitable for in-ceiling use.
On-wall versions available later in 2006: contact Meridian for details.
Passive versions are detailed in a separate datasheet.
