INPUT ATTENUATOR CONFIGURATION IN MODE MONO (MF16 AND MF24 ONLY)
The input attenuators (potentiometer), may be configurated in MONO mode
for the models MF16 and MF24. With the switch of configuration placed in the
input board not pushed, the input attenuators will be independent for each
channel (DUAL POT), and with this switch pushed, the input attenuator of the
channel 1 (CH1) will control both channels at the same time (MONO POT).
In the models MF8 and MF12 this input attenuator configuration don't exist, the input
attenuators are always independent for each channel.
The factory configuration is with the input attenuators independent (DUAL POT).
DUAL POT.
(Input attenuators independent for each channel).
MONO POT.
(Input attenuator of channel 1 (CH1) controls both channels).
LIMITER ON/OFF
The power amplifier's limiter reduces the input signal when the power amplifier starts to
saturate, which avoids high saturation and loudspeakers damage.
It is very advisable use the limiter circuit, mainly in applications with 2
Ω
loads.
When the limiter ON/OFF switch is not pushed, the limiter is enable (ON). When this
switch is pushed, the limiter is disable (OFF).
The limiter configuration (ON/OFF) affects to both channels of the power amplifier.
The factory configuration is with the limiter enable (ON).
LIMITER ON (enable).
LIMITER OFF (disable).
