5

Hz, 

80

 Hz, 

100

 Hz, or 

130

 Hz. All signals below

the selected crossover point are blocked; all
signals at or above the selected crossover
point go to your mid-bass speakers.

The 

MID BASS BANDPASS LOW

 crossover

point selector lets you set the upper frequency
limit for mid-bass output. To set the crossover
point, slide the switch to 

200

 Hz, 

300

 Hz, or 

500

Hz. All signals above the selected crossover
point are blocked; all signals at or below the
selected crossover point go to your mid-bass
speakers.

If you do not want to set an upper frequency
limit so that frequencies higher than 500 Hz
can go to your mid-bass speakers, slide the
switch to 

FLAT

.

Use the 

LEVEL

 control above the 

MID BASS

crossover point selectors to carefully adjust
the mid-bass output to the amplifier. Setting
the control too high could cause distortion.

Setting the MID Crossover Points

The crossover’s mid-range output also uses a
high-pass filter and a low-pass filter to form a
bandpass that lets only certain frequencies
through. There are two 

MID

 crossover point

selectors. The high-pass filter lets you set the
lower crossover point and the low-pass filter
lets you set the upper crossover point for your
mid-range output.

The 

MID BANDPASS HIGH

 crossover point se-

lector lets you set the lower frequency limit for
mid-range output. Slide the switch to 

200

 Hz,

300

 Hz, 

500

 Hz, or 

700

 Hz. All signals below

the selected crossover point are blocked; all
signals at or above the selected crossover
point go to your mid-range speakers.

The 

MID BANDPASS LOW

 crossover point se-

lector lets you select the upper frequency limit
for mid-range output. To set the crossover
point, slide the switch to 

1K

 (kHz), 

2K

, or 

4K

.

All signals above the selected crossover point
are blocked; all signals at or below the select-
ed crossover point go to your mid-range
speakers.

If you do not want to set an upper frequency
limit so that frequencies higher than 4 kHz can
go to your mid-range speakers, slide the
switch to 

FLAT

.

Use the 

LEVEL

 control above the 

MID

 cross-

over point selectors to carefully adjust the
mid-range output to the amplifier. Setting the
control too high could cause distortion.

Using the Remote Control

Follow these steps before you make adjust-
ments to the remote’s 

BASS EQ

 and 

SUB

 con-

trols.

1. Adjust the auto sound system’s volume to

a moderate level.

2. Adjust the crossover’s 

LIMITER

 control to

MIN

 (minimum).

3. Adjust the remote’s 

SUB

 control to a posi-

tion about halfway between 

MAX

 (maxi-

mum) and the dot preceding 

MAX

.

4. Adjust 

LIMITER

 toward 

MAX

 just until you

hear some distortion, then slightly turn
the control back toward 

MIN

 until the dis-

tortion goes away. (You want this control
set to the highest position possible with-
out causing distortion.)

5. Adjust the crossover’s 

BASS EQ

 control to

boost a specific frequency in the bass
equalizer. Begin by setting it to 

70

 Hz,

then adjust it as desired.

After making these adjustments, you can use
the remote’s 

BASS EQ

 control to boost the

crossover’s 

BASS EQ

 frequency level and the

remote’s 

SUB

 control to adjust the subwoof-

er’s output level.
