Monitor

As in Normal Mode except…
Single Port, Amber LED indicates channel monitored at headphones.
Solid indicates channel Sample Rate Converters in Auto

indicates channel forced to use Sample Rate Converter

Table 35: AES Module: Menu Modes

† Auto Mode: Sample Rate Converter is switched in if the difference between the input signal and the reference is greater than
700ppm.

†† Flashing is a hard on-off. Pulsing is a smooth sweep between 50 and 100% brightness

input

(receiver is not locked)

Green

Input is present, carries pcm data and is near rate* to reference

(input passed in directly)

Pulsing Green†

Input is present, carries pcm data, and is not near rate* to reference

(input is passed through sample rate converter)

Flashing Green†

Input is present, carries pcm data, and the sample rate converter has
been switched in manually

(either from the front switches or from the

2450).

Blue

Input is present, carries non pcm data and is near rate* to reference

(input is passed in directly. The non pcm status is determined from the non

linear pcm bits in the channel status. Input is deemed to be non pcm if either

sub frame carries non PCM data – typically Dolby E)

Red

Input is present, carries pcm data, is near rate* to the reference and
has a parity error, channel status CRC error or a bi-phase encoding

error.

Pulsing Red†

Input is present, is not near rate* and is either non pcm data or is
pcm data with a parity error, channel status CRC error or a bi-phase

encoding error.

Flashing Red†

Input is present, is near rate* to the reference and a sample slip has
occurred. Sample slips are indicated for 5 seconds after they occur

before the detector times out.

Amber

Selected Input Monitor Channel (routed to headphones) in auto mode

Pulsing Amber†

Selected Inpuot Monitor Channel (routed to headphones) sample rate
converter has been switched in manually

(either from the front switches

or from the 2450).
