FRAMES - DELAY
Using the Reference Selection Switch
The 2-position Reference Selection Switch allows for selection of the ADLY-4/A internal sample
rate to lock to and be set by the Reference Input BNC’s or AES Channel 1 input. With the switch
set as shown, in the down position, the ADLY-4 uses the AES3id signal present on the reference
BNC’s.
REF.
By placing the
Reference Selection Switch
in the up position the ADLY-4/A internal sample rate
is locked to and set by the AES Channel 1 input present on the 3 pin male Phoenix connector
labeled In 1.
Several things about the reference signal should be noted. First, there must be a valid AES
signal present on either one of the BNC inputs or the AES Channel 1 input at a sampling
frequency of between 30-50kHz. This can be verified by insuring that the
Reference LED is lit.
Secondly, the Frame Delay values set by the Frame Delay Switches are only accurate at a
48kHz sample rate signal. Third, the AES reference signal used should be phase lock looped to
the video using a VRG-1 (SoundPal Video Reference Generator) for accuracy.
