FlexFX Loop
This stereo loop connects an external effects pro-
cessor. The signals coming from the PGM 1 fader,
the PGM 2 fader, or both may be routed to the
FlexFX loop. This allows a single external effects unit to process
PGM 1 and/or PGM 2.
FlexFX switches are provided for PGM 1 and PGM 2. Press-
ing the FlexFX switch lights the green indicator and sends the
signal to the
external
FlexFX Loop. Press the switch again and
the channel is unassigned from the loop and the green indicator
goes off.
FlexFX jacks are unbalanced mono ¼" TS (Tip/Sleeve).
SEND jacks provide output to the effects processor. RETURN
jacks provide input from the effects processor. Effects insert
devices with a single in/out TRS jack place Send on the TIP and
Return on the RING. For this application, you will need a “Y”
cable, as shown below.
Send signals may be used as another auxiliary output, allow-
ing PGM 1, PGM 2 or both to be routed to an external source
(another amp or recorder).
It is not necessary to connect cables from FlexFX Send to
FlexFX Return as the FlexFX Return jack automatically con-
nects the Send to the Return when a cable is not connected.
Any signal assigned to the FlexFX Loop will be processed by
any internal digital effect assigned to the AUX BUS. This has
the advantage of allowing one of the two internal effects to be
assigned to the AUX BUS and then assigning PGM 1 and/or
PGM 2 to the FlexFX Loop. Internal digital effects are covered
on page Manual-8.
USB
USB Streaming Audio
There are up to eight channels of stream-
ing audio over the USB port. Two stereo
channels from the computer and two stereo
channels to the computer. While internal
processing is all 24-bit 44.1 kHz, streaming
audio is 16-bit 44.1 kHz. If the blue indica-
tor is on, the device is connected and communicating with the
computer.
Two stereo signals
from
the computer appear as Digital 1 and
Digital 2 inputs. These stereo digital signals may be selected for
PGM 1 and/or PGM 2 (see source selection in Program Controls
section).
Two stereo channels are sent
to
the computer. These may
be two independent stereo audio streams for recording -
or
- one
stereo audio stream for recording and one 4-channel stream for
vinyl emulation control. Scratch
LIVE
software selects the record
and vinyl emulation control sources.
When not using Scratch
LIVE
, the mixer appears as an 8-
channel sound card with two stereo channels in and two stereo
channels out. The source for the stereo output channels must be
selected in your software.
The following signals may be selected as the source for either
digital output to the computer:
PGM 1 Pre- or Post- Fader
PGM 2 Pre- or Post-Fader
Main Mix
AUX BUS (sum of MIC, AUX and FlexFX Return).
