Setting up the AV receiver

For your Columa 700 home cinema system with

active subwoofer, select the “small” or “normal”

(not “large”) setting in bass/speaker set-up of

the AV receiver for the satellites – this guaran-

tees that the satellites can be fully loaded and

the subwoofer and front speakers harmonise

perfectly with each other.

The subwoofer must be set to “On” in the bass/

speaker set-up on the receiver. The appropriate

cut-off frequency in this set-up for the Columa

700 is 110Hz (100/120/140/150Hz are also possi-

ble).

Setting up the subwoofer

When operating the system on the AV receiver, the

frequency control on the subwoofer/remote con-

trol must be set to “Maximum” = “140 Hz” becau-

se the cut-off frequency is set by the AV receiver

– its settings are dominant.

Modern AV receivers set the subwoofer phase

correctly when adjusting the distance of the

subwoofer from the listening location during

“speaker set-up” – so the phase controller on the

subwoofer itself should be left in the “0°” positi-

on. For older AV receivers, or appliances without

an option to compensate for the distance of the

subwoofer, the following applies:

With the phase controller, you can adjust the sub-

woofer to the satellites such that the speaker

membranes vibrate in the same direction in the

cut-off frequency range. If the phase is set incor-

rectly, the bass may be weakened or cancelled.

For a subwoofer position between the front spea-

kers, we recommend “0°” (grey field in the illus-

tration on page 8), for a position near the liste-

ning location “180°”. If the subwoofer is in another

location, the “180°” setting can balance out the

reduced bass playback. Set the phase controller

appropriately to get the strongest bass playback.

The volume setting of the subwoofer may be

slightly different when playing back music com-

pared with home cinema sound, depending on the

recording quality and mixing. Whereas a massive

bass element predominates on DVDs with high

quantities of special effects, the desired level is

sometimes not reached for music (especially if

the set has been set up for ideal DVD playback).

In this case, the user’s own taste is the main de-

termining factor in finding the right compromise

between the two sources.

This is how you can gradually find the best volume

for the subwoofer:

We do not recommend selecting an automatic

setting for the subwoofer using the integrated

calibration computer (if the receiver has such)

but rather setting the subwoofer in the bass/

speaker set-up to a high value between +8 and

+12 dB (around setting “55” on the subwoofer).

This guarantees operation of the auto on/standby

mode; then you can determine the ideal level for

the subwoofer by carrying out listening tests.

Subwoofer remote control

Volume

This sets the subwoofer’s volume. Increase the

volume using the “+” button and decrease it

using the “–” button.

Frequency

Here you can align the subwoofer’s cut-off fre-

quency with the satellite speakers. For operation

on the AV receiver press the “140 Hz” button. The

display on the front of the subwoofer then shows

»14«.
