13 CLIP-LIMITER SWITCH
If a very high level signal is driven into the amplifier , the output signal will "CLIP", that
is the peaks of the waveform will be flattered. The Clip Limiter circuit automatically
reduces the gain to prevent the overdrive. Y ou can switch the Clip Limiter circuit
ON and OFF via the (13) switch on the rear panel of your MAC 2 series. If you use
full range speakers, the Clip Limiter circuit will reduce the high frequency distortion
and it will also protect the high frequency drivers. However , some Users prefer to
switch the Limiter OFF to get more punch from Kick Drums and other sounds in
the low frequencies area.
14 LOW FREQUENCY FILTER
This Filter rolls off audio signals below 30 Hz. In this way bass performance will
be improved, because the subsonic motion of the cone will be cut out and more
power is made available to the woofer in the audible range of frequencies. If you
want our view: Keep the Filter ON most of the time unless you are filtering the
signal before the input of the MAC 2 series. Especially vented speakers (bass-reflex)
are very sensitive to subsonic frequencies (below 30 Hz).
15 OUTPUT MODE SELECTOR
The MAC 2.2/2.3/2.4 stereo power amplifier presents three operating modes:
- Stereo Mode
In this mode, channel 1 and channel 2 operate independently (as a normal stereo
amplifier). The channel 1 input signal will be output from the channel 1 output connector ,
and channel 2 input signal will be output from the channel 2 output connector .
- Parallel Mono Mode
In this mode, channel 1 input signal will be output from the output connectors of
both channels. Detail wiring diagram you can refer to chapter 4.
- Bridged Mode
In this mode, channel 1 input signal will be output from the bridge-mono output
connector . Detail wiring diagram you can refer to chapter 4.
16 COOLING FAN
This fan secures enough cooling for your MAC 2 series amplifier . The airflow is front-to-rear .
The fan speed is electronically regulated depending on the temperature of the power
devices.
