INPUT 2. Note,however,that this is not possible if the
the OPERATION MODE switch is set to SEPARATE.
7 ATTENUATOR
This Knob allows you to adjust the attenuation in 31
stages.In dual and bridge modes it functions as a volume
control : 0 dB when turned full right, and - ∞ when turned
full left. In Separate mode it functions as an attenuator
for adjusting the volume of the high-frequncy channel
(0 to -15 dB,in 0.5 dB steps): turning it to the left lowers
the volume.

nnecting to your M-AX10.
Bridge conection
•
The four channels are connected two by two, so as to
act as two high-output amplifier channels.
Output comprises two 230 W/ 6 Ω (DIN),200 W/ 6 Ω (FTC)
•
channels.
Your speakers must be at least 6 Ω .
•
Dual conection
•
The four channels act as two parallel sets of twin amplifier
channels.
Output comprises two 110 W/ 3 Ω (DIN),90 W/ 3 Ω (FTC)
•
channels.
•
Speakers with bi-wire terminals will allow you to achieve
high-quality sound.
Separate conection
•
The channels act separately as four amplifier channels.
Output comprises two 110 W/ 3 Ω (DIN),90 W/ 3 Ω (FTC)
•
channels.
•
Connecting a channel divider will allow you to use the
appliance as an amplifier for a multi-channel system.
•
You can adjust the volume of speakers connected to the
HIGH channels (INPUT 1) in a range from 0 to 15 dB.
You can also retain the attenuation once you have set it.
