Positioning

The KC62 is side-firing, therefore there should be a minimum of 77mm (3″) clearance between the drivers and any wall.

Low-frequency sound can travel through walls and be heard in adjacent rooms. To avoid disturbing neighbors set the EQ to “APARTMENT MODE” to reduce the level of very low frequencies.

Connection to LINE INPUT from a preamp or receiver

Connection to SPEAKER INPUT from a stereo amp or receiver

LFE connection to 2 subwoofers

You can use the LINE OUT high pass frequency (HPF) of the KC62 to match the KC62’s frequency response to speakers.

1. Connect the amplifier for the speakers to the LINE OUTPUT
2. Adjust the high pass frequency through LINE OUT HPF to optimize the performance of the speakers. Please refer to the frequency settings on the table.

Controls

Crossover frequency control & mode
The crossover frequency control changes the upper cut-off frequency of the subwoofer. Its effective range is from 40Hz to 140Hz at a rate of 24dB per octave. The frequency control should be adjusted to achieve the smoothest integration between the main/satellite speakers and the subwoofer. Clockwise rotation will increase the cut-off frequency and anti-clockwise rotation will decrease the cut-off frequency.

1. Ideal crossover – flat response.
2. Crossover point set too low – causes dip in combined response.
3. Crossover point set too high – causes hump in combined response.

If your receiver/preamp does not have a subwoofer crossover

1. Set the “Mode” button to MANUAL.
2. Start with the crossover on the subwoofer at 80Hz and adjust up or down till you find the best match with your speakers.

If your AV amplifier/receiver/preamp has a subwoofer crossover

1. Set the “Mode” button to LFE
2. Start with the crossover on the AV amplifier/receiver/preamp at 80Hz and adjust up or down till you find the best match with your speakers.

| Volume control
The volume control adjusts the output level of the subwoofer in relation to the satellite or AV speaker output level. Clockwise rotation to increase the output level or anti-clockwise to decrease the output level.
---|---
| Phase control
The phase control will normally be set at 0º but more output level can sometimes be achieved in the 180º position, particularly when the subwoofer is far away from the satellite speakers.
| Ground lift
If you hear ground-related noise, make sure your system is properly grounded and that all antenna, satellite, or CATV lines are properly grounded. If noise continues,  set the “GND LIFT” button to “ON” to reduce or eliminate any remaining ground noise
