INPUT (DOWNMIX) Button

Selecting Input Sources or User Presets for Monitoring: > INPUT Button

The INPUT Button is used to select the input source or user preset to be monitored.

In Normal Operational Mode each press of the INPUT Button cycles through the following sources: Analog, AES1

(unbalanced), AES2 ( balanced), SD-SDI1 (or HD-SDI1), and SD-SDI2 (or HD-SDI2). In models without SDI capability,

only the Analog and AES inputs are cycled through.

When Preset Mode is enabled (see Preset Mode Enable section on page 29), each press of the Input Button cycles through

the named presets set up by the user (instead of cycling through the available inputs).

Enabling Downmix Mode and Selecting Mixes: > FN Button + DOWNMIX Button

In Downmix Mode the user may select from a number of different preconfigured mix types for monitoring through the

speakers. Downmix Mode is enabled by pressing and holding the FN Button and then pressing the DOWNMIX Button.

The seven downmix selections are cycled through using the L UP and L DOWN Buttons or R UP and R DOWN

Buttons. See Downmix Selection on page 25 for a description of all Downmix selections available.

ΦΦ

(FN) Button (Phase Indication and Function)

Enabling Phase Indication Mode: >

ΦΦ

Button

Pressed by itself, the

ΦΦ

Button enables the Phase/Correlation Indicator in the LCD Display. The average

correlation (phase) for the selected channel pair is indicated by a stationary block in one of three positions on the

second line of the display. A moving block may also be present in these positions to indicate the instantaneous (short

time sample) phase correlation. The three positions are as follows:

Center: Only one channel active or zero correlation between the two channels

Left (-): Selected channels are out-of-phase (-1 correlation maximum)

Right (+): Selected channels are in-phase (+1 correlation maximum)

Note: With typical stereo program material, the moving block display is normal. With a single signal, or two completely un-

related signals selected for the speaker(s), no correlation information is available, so the phase indicator block will be at rest

in the center of the LCD. A mono in-phase signal fed to both right and left channels would result in the block being in the

right-most position indicating complete correlation of the two signals.

Enabling Channel Select Modes and Setup Mode: > FN Button

Pressing and holding the FN Button and then pressing an additional button puts the unit into one of the alternative

modes. Below is a list of modes enabled by pressing and holding the FN Button and then pressing one of the other

buttons. See the reference for each button for information about the indicated mode.
