About the ADLY-4/A
The RJM & Associates SoundPals ADLY-4/A is an 8 channel (4 AES pairs) audio delay solution
which ties the audio delay to video frame delay values. The ADLY-4/A delays all 8 channels up to
99.9 video frames at 24, 25 or 30 frames per second and is adjustable in 0.1 frame steps using
three decade switches. It also has a reference switch selectable to either the external AES3id
loop-thru reference BNC’s or the AES channel 1 Input. There are four valid AES input led’s as
well as a valid reference led. The unit will accept any sample rate between 32kHz and 50kHz.
The unit offers the following features:
•
Four AES (8 channels) balanced inputs
•
Four AES (8 channels) balanced outputs
•
10-position rotary 0.1 frame delay switch
•
10-position rotary 1.0 frame delay switch
•
10-position rotary 10.0 frame delay switch
•
Frame rate selection switch
•
External AES3id reference loop thru BNC’s
•
Valid AES indicator led’s (4 each)
•
Valid reference led
•
Data Resolution: 24 Bits
•
All Channel Status and User Bits pass through at same delay as audio
•
Optional rack mounting tray (1 RU)
•
Optional rack mounted (1RU) XLR Input/Output Panel (8 AES pairs each)
•
Compact size, rugged construction
Note that the ADLY-4/A can synchronize to any sample rate between 32kHz and 50kHz, but is only
video frame accurate at 48kHz.

1)
Video Frame Rate Switch
— selects the video frame rate in frames per second.
2)
X10 Frame Delay Switch
— the 10-position rotary
X10 Frame Delay Switch
allows you to
select frame delay in multiples of 10 frames per step. (Note: frame rate is only accurate at
48kHz sample rate.)
