At the back of this manual are die-cut overlay cards that can be placed over the
rear connector BNCs to identify the specific 8914 connector functions.
Inputs
The 8914 Dual AES/EBU Delay DA has two channels. Delay 1 is a 1x4 DA
with a looping input. Delay 2 is a 1x3 DA with a terminated input. Trans-
former coupling on the inputs eliminates common mode noise.
For a delay channel 1 signal, connect an input source to one of the
loopthrough input connectors, J9 or J10 (See
). Terminate the
unused connector into 75
Ω
. Use J7 for input to delay channel 2. J7 is inter-
nally terminated into 75
Ω
.
