FEATURES
This device is a crossover network for multiple channel
speaker system. It divides playback frequency into two
or three ranges to enable the specially designed
amplifiers and speakers to provide such 2- or 3-way
playback. |
The crossover frequency can be adjusted as desired
between LOW to MID range and MID to HIGH range. As
the phase of the LOW range output and the HIGH range
output can be switched, the acoustic characteristics can
be set to suit the interior of the car or the speakers that
are used.
e¢ The sound level can be controlled with dials for each of
LOW, MID and HIGH ranges according to the power
amplifiers and speakers used as well as the interior
condition.
e Input and output terminals are plated with highly
electricity-conductible gold for improved tone.
¢ LOW OUTPUT can be set to either stereo or monaural
according to the power amplifier and sub-woofer used.
important
The serial number of this device is located on the bottom of
the unit. For your own security and convenience, be sure to
record this number on the enclosed warranty card.
