Send/Return (Insert) to Direct Out
Changes a channel's ¼­inch insert jack to a Direct Out jack.
1. Remove jumpers at X101, X102, X105 and X106, and X808 if modifying channel 8.
2. Short resistors R1011 and R1020.
Send/Return to Direct Out Post-Fader
A channel's Insert phone jack can be changed to Direct Out, post­fader.
1. Remove jumpers at X101, X102 and X105.
2. Short resistors at R1020.
Remote Volume Control of Channels
The channel, aux, or master levels can be controlled remotely by a dc voltage via an external VCA (Voltage Con­
trolled Amplifier). An example of an external VCA is the ST­VCA1 from Radio Design Labs (1–800–281–2683 or
www.rdlnet.com).
Procedure:
For channel control:
1. Connect the tip of a ¼-in. connector to the line input of the VCA, and the sleeve to the ground of the VCA.
2. Connect the ring to the line output of the VCA.
3. Plug the ¼-in. connector to the Insert jack of the SCM800.
4. Set the channel level control should be set to 5.
For Aux In control:
1. Connect the external source to the VCA line input.
2. Connect the VCA line output to the tip and sleeve of the SCM800 Aux input.
3. Set the Aux control to 5.
For Master control:
1. Connect SCM800 Line output to the VCA line input.
2. Connect the VCA line output to the external device (amplifier, tape recorder, etc.).
3. Set Master control to 5.
