X1 Frame Delay Switch
— the 10-position rotary X1
Frame Delay Switch
allows you to
select frame delay in multiples of 1 frame per step. (Note: frame rate is only accurate at
48kHz sample rate.)
4)
X.1 Frame Delay Switch
—
the 10-position rotary
X.1 Frame Delay Switch
allows you to
select frame delay in multiples of 0.1 (10
th
of a frame) frames per step. (Note: frame rate is
only accurate at 48kHz sample rate.)
5)
Reference LED —
when lit
this green led
indicates a valid AES reference either using the
external reference BNC’s or AES input channel 1 depending on the selection of the
Reference Switch
on the rear of the unit.
6)
Valid AES Input
led’s —
these four green led’s indicate you have a valid AES input for the
led that is illuminated.
7)
PWR
— the green
Power LED
lights when power is applied.

Power Connector
— accepts the power jack from the 6 VDC supply. Refer to
“External
Power”
for more information on external power.
2)
AES3id Unbalanced Inputs —
provides 4 AES3id unbalanced channel inputs via a BNC
connector for each AES3id input channel.
3)
External Reference AES3id Loop Thru BNC’s —
provides a BNC external input
AES3id reference signal input, which can be looped thru, when the
Reference Selection
Switch
is in the down position. Note that when not using these BNC’s as a loop-thru the
open BNC should be terminated with 75 Ohms.*
4)
Reference Selection Switch
— in the down position selects the AES reference from the
External AES3id Reference BNC’s. In the up position selects AES3id input channel 1 as
the reference.*
5)
AES3id Unbalanced Outputs —
provides 4 AES3id unbalanced channel outputs via
BNC connectors, one for each AES3id output channel.
* The AES reference signal, either external or AES channel 1, must have a sampling
frequency between 30kHz and 50kHz.
