7.3.5 Delay Block
❑
There are two delay lines, each independently adjustable.
❑
The feedback (recirculation) signals for the delay lines are cross-coupled.
❑
The feedback setting is always the same for both delays.
❑
For clarity, the diagram shows the "mix pots" reversed. When the mix parameter is 0, both
outputs are their respective input signals. When the mix parameter is maximum, both
outputs are the lowpass filtered delay line outputs.
❑
The MIDI edit buffer parameter numbers are shown in parenthesis.
7.4 System Interface
The 601 can be used in a variety of ways, some of which may be obvious, some of which may
not be so obvious. The next portion of this chapter describes some of the different ways to use
the 601.
7.4.1 Using the 601 as a Channel Insert Device
The 601 can also be used as a channel-insert device with your console. Use the 601's line input
and one or both of the 601's line outputs. If you use both line outputs, then you'll need a
second channel at your console for the 601's second line output.
7.4.2 Using the 601 in a Send-Receive Loop
The 601 can also be used in a console's send-receive (effects) loop. Drive the 601's line input
from the console's effects send and feed one or both of the 601's line outputs to your consoles
effects returns. Ensure that the 601's delay mix parameter is set at 100%. If you use both of
the 601's line outputs for stereo, then you'll need a stereo effects return or a second mono
effects return for the second line output.
