RANE SL1 FOR SERATO SCRATCH LIVE • OPERATOR’S MANUAL 2.4.4 7
Connecting Your
Hardware
The Scratch Live control records and
CDs are pressed with an audible tone
specifically developed for controlling the
Scratch Live software application.
The SL1 interface 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,
with any manipulation of the control discs
reproduced on the audio, effectively
emulating vinyl control of the files loaded
in software.
Connecting the SL1
To integrate an SL1 unit into a typical DJ
setup, connect it to your turntables (or CD
players) and mixer as follows:
Connect the Turntables or CD Players.
Plug the cables from your decks, into the
input sockets of the SL1, plugging the left
deck into input 1 and right deck into input
2.
Connect the Line Outputs to your Mixer.
The output from Scratch Live comes
from the OUTPUTS on the SL1. Using the
included RCA cables, Connect the LEFT
DECK LINE OUTPUTS into a left line input
your mixer, and the RIGHT DECK LINE
OUTPUTS into a right Line Input of your
mixer. If your mixer has selectable input
levels, set these to Line level.
Connect your Thru Outputs to your
Mixer. The THRU outputs on the SL1
are used if you want to play regular vinyl
or CDs during your set. They allow you
to bypass your Scratch Live software,
sending audio direct from the SL1 inputs
to your mixer (i.e. the sound from your
records or CDs). Connect these to your
mixer inputs, matching the level of your
decks. In general, turntables are phono
level, and CD players are line level.
Once your THRUS are connected, you
can switch to your vinyl or CD’s using the
phono/line switch or transform switch on
the top of your mixer.
If you hear the sound of your control
discs instead of music from Scratch Live,
you are listening to the thrus rather than
the line outputs.
The thrus only work when the SL1 is
powered, either by a computer over USB,
or by the optional DC power supply.
Connect the SL1 to your computer.
Using the provided USB cable, connect
your SL1 to an available USB port on
your computer. Connect it directly to
your computer and not through a hub or
splitter.
Turntable Setup
Set the tone arms to the
recommendations of the cartridge, such
that the needle never leaves the record,
but not heavy enough that it heats up
significantly. Both produce poor tracking.
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
Disable all built-in effects on the CD
player, including keylock/master tempo.
Ensure the input level in Scratch Live is
set correctly to accept a LINE level signal.
See “Audio Input Level” on page 30.
