2.0 Front Panel Controls

2.1 Input and Meter Selection Buttons

AES1, 2, 3 & 4 AES input. This is selected by first pressing the AES select

button, then selecting A(1/2),B(3/4), C(5/6 ), D(7/8) respectively
on the LS monitoring panel.

Anal ogue 1 & 2 These inputs are selected by pressing the Phase

Reverse/function button and then the AES/ANLG button on the
input select panel. The signals are displayed on bargraph A
(1/2) and B (3/4).

S/HD (Auto sensing) This is selected by pressing the S/HD button 1 or 2 and then

selecting GP1 to GP4. The de-embedded SDV or HD is then
displayed on the bargraphs A(1/2),B(3/4), C(5/6), D(7/8)
respectively. Selecting e.g. group 1 and 2 together allows all
eight channels to be monitored.

Dolby Encoded Dolby can either be carried on an AES bit stream or

as embedded HD or SD. To select the Dolby function press the
DOLBY button after selecting either AES or S/HD buttons. If a
valid Dolby signal is present the Dolby button will illuminate
steady red. If a Dolby signal is not present or is lost the button
will flash. To select one pair from one group containing two
Dolby signals on each pair, select the group (1, 2, 3 or 4) from
the H/SDV input and then either A, B, C, or D from the input
selector to choose the pair.

Letterbox Shows the composite output as 16:9 aspect ratio on a 4:3

monitor.

Ø Rev (Function) Momentary phase reverse between A1 and A2 outputs.
Brightness To increase the brightness of the ba rgraph disp lay

Press phase reverse and monitoring select A. To
decrease the Brightness press phase reverse and
monitoring select B.

Reference Marker To turn the reference marker on and off press phase
Reverse and the CUT button.
