Basic Operation

JBL

INPUT

Indicates the current input (i.e. DVD1).

INPUT TYPE ANLG, BYP, PCM, ---

Indicates the input source that is present. When the parameter setting is ANLG, an analog audio source is present and the MAIN ADV menu ANALOG BYPASS parameter is set to OFF. When the parameter setting is BYP, an analog audio source is present and the ANALOG BYPASS parameter is set to ON. When the parameter setting is PCM, a 2-channel digital audio source is present. When the parameter setting is ---, a sample rate is detected, but no audio is detected in the digital audio input signal.

MIX ROOM SMALL, LARGE

Indicates the size of the mixing room that was used during the mixing process. When the parameter setting is LARGE, it is recommended to set the RE-EQUALIZATION parameter to ON for THX listening modes.

MODE

Indicates the current (activated) listening mode (i.e. L7 FILM).

SAMPLE RATE 44.1kHz, 48kHz, 88.2kHz, 96kHz

Indicates the sample rate of the input source that is present.

SURR MIX LVL +0.0dB, -3.0dB, -6.0dB

Indicates the relative surround channel level that was used during the mixing process.

WORD LENGTH 16bits, 20bits, 24bits

Indicates the word length of the audio data present in the input signal.

Status Menu Level Meters

Most status menus contain level meters that indicate fluctuating input levels in the front left (L), center (C), front right (R), surround left (SL), surround right (SR), surround back (SB), and LFE (LFE) channels. These level meters indicate input levels for both analog and digital audio sources. For instance, the level meters indicate digital audio input levels when a digital audio source is present.

Different combinations of level meters appear on each status menu, depending on the input source that is present. The SB level meter appears when a 6.1-channel source is present, or when a 5.1-channel source is present and the ES DECODING parameter is set to ON.

Level meters appear in combinations of green, yellow, and red when the on-screen display is configured for a blue-screen background. Green indicates low input levels, yellow indicates normal input levels, and red indicates high input levels and the onset of overload. Level meters appear in white when the on-screen display is not configured for a blue-screen background.
