FlexFX Loop
This stereo loop connects an external effects proces
-
sor. 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. (See internal digital effects on page 8.)
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 to stop
sending signal to the loop (the green indicator goes dark).
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).
If you wish to disconnect your external effects processor, it
is not necessary to connect cables from FlexFX Send to FlexFX
Return, as the TTM 57SL detects the presence of cables, and
automatically connects the Send and 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 as
-
signed to the AUX BUS and then assigning PGM 1 and/or PGM
2 to the FlexFX Loop.
USB
USB Streaming Audio
There are eight channels of streaming 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 indicator is on, the
device is connected and communicating with the computer. For
troubleshooting connection problems see page 41.
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).
As well as the 2 stereo channels sent to the computer for vinyl
emulation control, one stereo pair can also be sent to your com-
puter for recording. See Recording on page 30.
When not using the Scratch
LIVE
software, the mixer appears
as two four-channel sound cards with stereo in and stereo 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).
