M•2600
The Mackie Designs M•2600 is a dual channel,
high output power amplier that incorporates a
number of unique features including FR “Fast
Recovery” design, high continuous current output,
and a T-Design constant gradient cooling tunnel for
improved cooling efciency and output device reliability.
The M•2600 is rated at a continuous output of
425 watts per channel into 8Ω, 700 watts per channel into 4Ω and 1000 watts into 2Ω. In bridge mode
the M•800 is rated at 1400 watts into 8Ω and 2000
watts into 4Ω. Variable low-cut lters on each channel with a range from off to 170Hz enable tighter
bass response. The built-in limiter helps eliminate
clipping. Inputs are balanced/unbalanced 1/4" and
XLR, and XLR thru outputs are switchable to send
either the full-range signal, or the post-crossover
low-frequency or high-frequency output, to another
amplier. Speaker connections on the M•2600 are
1/4" and Speakon® connectors, with an additional
Speakon output for mono bridge operation. An amp
mode switch selects stereo, mono, or bridge operation.
To effectively deal with clipping, an amplier must
be able to recover almost instantaneously. That is the
denition of “Fast Recovery.” Rather than using negative feedback to help control clipping distortion, the
M•2600 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 transistor senses when the Baker Clamp
is active and activates the internal limiting circuits.
This results in no latching, instant recovery from overdriving the amp, and a superior sound.
