EFFECT LEVEL controls the loudness of the front, side and rear outputs.

The AUTO AZIMUTH/BAL (short for Auto Azimuth Error Correction/ Automatic Input Balance) parameter should be set to ON for films, OFF for music. When it is on, special patented algorithms continually monitor the input signal and adjust both the relative level and time offset of the two channels to keep the dialog properly centered and special effects properly localized. This automatic feature is why the CP-3 does not have or need an input balance control for Dolby Surround decoding.

BASS SPLIT takes the low bass from the center, where it is in many film and music mixes, and distributes it instead to the left and right front-channel speakers. Bass Splitting is valuable because in many video installations the center speaker is smaller than the two main stereo speakers and is less capable of handling the lowest frequencies. By directing the low frequencies to the main speakers, there is less risk of damage to a small center speaker and no loss of bass information since it will be reproduced by the main speakers.

SUB BASS BOOST boosts or cuts the subwoofer output level. Although the normal subwoofer level was set during the initial calibration procedure, with some recordings you may find it desireable to increase or decrease this deep bass level.

SIDE SPEAKER ASSIGN determines whether the information fed to the side outputs is derived from the front left and right, or from the rear. Choosing the front setting will create a very wide soundstage, which can be very exciting on some soundtracks. On others, particularly those with panned dialog and very tight localization of sound effects, the soundstage will be too wide. Technically, the rear setting is a closer match to the original recording format.

In Pro Logic, MAIN MUTE mutes the center output; EFFECTS MUTE mutes the front, side and rear outputs.
