■ Step 1-B : [ SOUND MODE ] Sound Preferences Switches
Advanced configuration tools for EQ and DSP.
TIP: These setting changes are instant. No power cycle is necessary.
#6,7 [ BGM Mode ]
Select a Sound Mode based on the intended
“mood”
of the listening environment.
If using this unit to expand the MCA1120, set to [ Off ].
The Sound Mode of the MCA1120 will
carry over.
#8-10 [ Preset EQ for Loudspeaker ]
Select the EQ preset for your speaker type(see list below).
#3-5 [ HPF (High Pass Filter) ]
Depending on the purpose of this unit, settings are different. Please refer description below.
* When it is used as speaker amplifier.
・Use this filter to limit bass frequencies to the SPEAKER OUT terminals. The DIP switches
set the cutoff frequency.
* Only if it is used as Subwoofer amplifier (When Switch #2 is [ On ])
・These settings are for low pass filter.
NOTE : Do not set to [ Off ] when using Hi-Z speaker or the amplifier may go into
protection mode.
NOTE : Settings of DIP switch are different from MCA1120.
