After these steps are completed the display
appears as:
12.1.10.12. Subwoofer Setup:
The steps in the following four sections set up
the optional subwoofer channel in outputs one
and four. This provides a summed signal in both
outputs to drive one or two mono subwoofers.
For a setup for two independent stereo subs,
refer to our website.
(Skip the next four
sections if you are not using a subwoofer.)
12.1.10.13. Step Ten: Select SUM Signal to Drive a
Mono Subwoofer.
The next step forms a sum signal from inputs “A”
and “B” to drive the subwoofer. This is found on
page 1 of 5 of the SUM menu.
Press [SUM] and turn [KNOB] to select
[A+B]
The front-panel display will then show:
12.1.10.14. Step Eleven, Select Sum as Source for
Subwoofer Outputs:
The next two steps connect outputs one and
four to the input’s sum signal to be used as a
source for the subwoofer. This is found on page
1 of 8 of the menus for outputs one and four.
Press [OUTPUT 1] and turn [KNOB] to
select [SUM]
Press [OUTPUT 4] and turn [KNOB] to
select [SUM]
After these two steps, the following photo shows
the display for output one. Not shown is the
corresponding photo for output four.
12.1.10.15. Step Twelve, Set Up Subwoofer Filter:
Set the subwoofer low-pass filter crossover
frequency and filter type for both sub outputs.
Press [PAGE>] and set low-pass filter to
TYPE: [L-R24] FREQ: [80Hz]
Press [OUTPUT 4] [PAGE>] and set low-
pass filter to TYPE: [L-R24] FREQ: [80Hz]
After these two steps, the following photo shows
the display for output one. Not shown is the
corresponding photo for output four.
12.1.10.16. Step Thirteen, Set Up Mid-Bass Filters:
The following step configures the mid-bass high-
pass filters for use with the subwoofer(s). This is
accomplished by moving the crossover
frequency for the mid-bass high-pass filters up
to the same frequency as the subwoofer low-
pass filter and changing the filter type to L-R24.
NOTE:
Linking still operates for these outputs so
there is no need to explicitly set output five.
Press [OUTPUT 2] [PAGE>] and set the
high-pass filter on page 2 of 8 to TYPE: [L-R24]
and FREQ: [80Hz]
The next photo shows the display after this step.
12.1.10.17. Step Fourteen: Un-mute all Crossover
Outputs:
Press [OUTPUT 3] to return to the main
menu.
Press [MUTE] [OUTPUT 1] [OUTPUT 2]
[OUTPUT 3] [OUTPUT 4] [OUTPUT 5]
[OUTPUT 6] [MUTE]
