M•800
The Mackie M•800 is a dual channel, high output
power amplifier that incorporates a number of unique
features including FR “Fast Recovery” design,
high con-
tinuous current output, and a T-Design constant-
gradient
cooling tunnel for improved cooling efficiency and out-
put device reliability.
The M•800 is rated at a continuous output of 150
watts per channel into 8
Ω
, 225 watts per channel into
4
Ω
and 280 watts into 2
Ω
. In bridge mode the M•800
is rated at 450 watts into 8
Ω
and 560 watts into 4
Ω
.
Variable low-cut filters on each channel, with a range
from Off to 170Hz, enable tighter bass response and
a Constant Directivity Horn EQ improves high-frequency
reproduction. The CD Horn EQ is 6 dB/octave and
its “knee” position is sweepable from 2kHz to 6kHz.
The built-in limiter helps eliminate clipping. Inputs are
balanced/unbalanced 1/4" and XLR, and XLR thru con-
nections allow the full-range signal to be routed to
another M•800. Speaker connections on the M•800
are 1/4" and binding posts for the U.S. version, and
Speakon® and binding posts for the international ver-
sion. An amp mode switch selects stereo, mono, or
bridge operation.
To effectively deal with clipping, an amplifier must be
able to recover almost instantaneously. That is the defi-
nition of “Fast Recovery.” Rather than using negative
feedback to help control clipping distortion, the M•800
employs a very sparse amount of negative feedback.
The use of Baker Clamp circuits on the positive and
negative voltage amp stages prevents saturation (and
latching) during periods of overdrive. In addition, a tran-
sistor senses when the Baker Clamp is active and acti-
