TTM 57SL FOR SERATO SCRATCH LIVE • OPER ATOR’S MANUAL 1.9.2
11
TROUBLESHOOT: The TTM 57SL mixer is not
recognized. It takes ve seconds for Scratch
Live to detect the TTM 57SL. The mixer can be
unplugged at any time; you do not need to exit
Scratch Live before disconnecting the hardware.
Use the supplied USB cable — longer lengths
are not recommended. On some Windows
machines each USB port is treated separately,
so you will need to install the driver separately
for each USB port.
USING THE TOOL TIPS
Click on the ? icon to enable tool tips. Tool tips
provide a handy way to learn the various features
of Scratch Live. Move the mouse over a section
of the screen to bring up a context-sensitive
tool tip. Holding the mouse over the ? button
with tool tips turned on will show you a list of
all keyboard shortcuts. Tool tips are available in
several languages. Scratch Live will display the
tool tips in the language that your computer is
set to. If your language is not available, the tool
tips will be displayed in English.
CONNECTING YOUR
HARDWARE
SYSTEM OVERVIEW
The Scratch Live control records and CDs
are pressed with an audible tone specically
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 les loaded onto the virtual decks are
then played back through the outputs of the
hardware, with any manipulation of the control
discs reproduced on the audio, effectively
emulating vinyl control of the les loaded in
software.
CONNECTING A TTM 57SL
To setup a TTM 57SL mixing audio from Scratch
Live, using two turntables or CD players to
control the software playback, follow this quick
guide.
1. Connect your left decks output cable to the
input 1 sockets on the rear of the mixer, and
your right decks 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 channels 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 specic
recommendations of the cartridge used, such
that the needle never leaves the record, but
not heavy enough that it heats up signicantly.
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 post of your DJ
mixer. 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 input level on the TTM 57SL is set
correctly to accept a LINE level signal.
Disable all built-in effects on the CD player,
including keylock/master tempo.
