CHAPTER 4

Subwoofer Mode

The subwoofer output can be set to Normal, or to an Enhanced Bass mode.

The Enhanced Bass mode pro- vides an output to your subwoofer even when you are listening to a stereo source with main speakers set to Large. In the Normal mode, there would be no subwoofer output in this case, and the bass would only come from the main speakers.

The Enhanced Bass mode has no effect if the main speakers are set to Small, as the subwoofer is automati- cally engaged. It also has no effect in 5.1 or greater surround modes.

AMPLIFIER

AUX CHANNELS SURR BACK

AmpliÞer Menu

The Receiver has two auxilliary ampliÞer channels which can be used to power the surround back, side-axis, or Zone 2 speakers. This menu allows you to select which of these is sent to the Aux ampliÞers.

User's Manual

Crossover adjustment

The Receiver's bass management allows you to redirect the low frequen- cies of your speakers to a subwoofer. The crossover point of your main left and right speakers can be selected from 40 Hz to 160 Hz, as can the crossover point of your center and surround speakers.

A setting of 80 Hz is a good start- ing point if you are not sure of the response of your speakers. In this example:

• The subwoofer receives frequen- cies below 80 Hz, from all speak- ers whose size is set to Small.

• All speakers set to Small, receive frequencies above 80 Hz.

Most manufacturers provide a -3 dB speciÞcation for their speakers. This is the frequency where the speaker's output has dropped by 3 dB. Set the Receiver's crossover to this frequency or above. If you cannot Þnd this, set the crossover to 80 Hz (the default).

Set your subwoofer's own cross-
over control to maximum frequency
or bypassed mode. If it is lower than
the Ultimate Receiver, there would
be a hole in the mid-bass, and bass	41
information would be missing.
