SYSTEM OVERVIEW
The Scratch Live control records and CDs
are pressed with an audible tone specifically
developed for controlling Scratch Live.
The Scratch Live audio hardware converts
the control signal coming from each deck into
digital audio, to be sent via USB to the Scratch
Live software, which decodes that signal into
a stream of information based on what the DJ
is doing with the control disc. A virtual ‘Deck’
replicates the movements of the control disc.
Audio files loaded onto the Virtual Decks are
then played back through the outputs of the
hardware. Any manipulation of the control discs
is reproduced on the audio, effectively emulating
vinyl control of the files loaded in software.
CONNECTING A TTM 57SL
To set up the TTM 57SL for Scratch Live, using
two turntables or CD players to control the
software playback, follow this quick guide.
1.
Connect your left deck’s output cable to the
PGM input 1 sockets on the rear of the mixer,
and your right deck’s outputs into input 3.
2.
Match the L channel from each of your decks
(usually white) with the white (uppermost)
RCA sockets on the mixer and R (usually red)
with the red sockets. This is important to give
Scratch Live the correct direction of playback.
If your songs play backwards, you probably
have the left and right channels swapped from
your deck.
3.
Set the input level dip switches for inputs 1 and
3 to LINE or PHONO to match the output level
of the respective decks. (In general, PHONO
for turntables, and LINE for CD players).
For example if you
have one turntable
connected to input
1 and a CD player
connected to input
2, push dip switch 1 down into the PHONO
position, and dipswitch 3 up into the LINE
position.

.
4.
Select Scratch Live as the audio source for
the mixer by turning the input selector knobs
on the top of the TTM 57SL to D1 and D2 on
the PGM1 and PGM2 channels respectively
.
TURNTABLE SETUP
1.
Set the tone arms to the specific
recommendations of the cartridge used, such
that the needle never leaves the record, but
not heavy enough that it heats up significantly.
Both produce poor tracking.
2.
Grounding is extremely important when
using Scratch Live. Make sure you have good
connections from the ground wires of your
turntables to the grounding posts of the TTM
57SL. All DJ mixers with turntable inputs have
built in grounding points for this purpose. If
you do not ground your turntables properly,
the control signal will be noisy and the tracking
of the record position will be erratic.
CD PLAYER SETUP
Ensure the dip switch for the CD player input on
the TTM 57SL is set correctly to accept a LINE
level signal.
SEE “PGM INPUTS 1-4” ON PAGE 7
.
Disable all built-in effects on the CD player,
including keylock/master tempo.
