Output Level Metering
An accurate 24 segment peak reading LED bar meter shows the incoming signal level from
-50dBfs to 0dBfs plus separate overload LEDs for each channel.
QUICK SETUP PROCEDURE
Plug in the left and right channel inputs on the rear of the unit, preferably using balanced wiring.
On the front panel set the “
Input Level for 0dBfs
”
mode
switch to the correct setting -
calibrated
if in a studio and the entire system is calibrated, or
variable
in any other situation.
Whilst paying close attention to the
Output Level Meter
, adjust the relevant input gain (The input
controls are analogue and thus measured in dBU whilst the meter displays the digital output of the
unit in dBfs, hence the +28 to 0 dBU controls). The levels should be set so that the meter is as
close to 0dBfs as possible without drifting into overload, to obtain the optimum output levels.
With your desired digital equipment connected to the any of the
O/P 1 digital outputs
(they work
simultaneously), and also connected to the
wordclock outputs
, on the front panel set the top row
(
O/P1
) of the
Output Sample Rate
to the desired rate, and set the
Bit Depth
.
Where a digital backup of your audio is required, connect the equipment to the
O/P 2 digital
outputs
on the rear panel, and set the bottom row (
O/P2
) of the
Output Sample Rate
to the
desired rate, and set the
Bit Depth
.
If you wish to set the wordclock using an external source, plug in the device to the
Wordclock
Input
on the rear panel and set either or both
Output Sample Rates
to
EXT
. If the signal is strong
the
Lock
led will light, if weak or unstable the Led will flicker or not light at all. In this case the
external device and wiring should be checked.
