While Scratch Live is not running, and the
SL4 is powered by the external supply, the Deck
Thrus on the SL 4 will always be on, allowing
you to play regular CDs and vinyl with your CD
players or turntables.
When the SL 4 is powered by the universal
power supply, and then Scratch Live is launched,
the Deck Thrus are still on. This allows a laptop
to be connected during a set (when using the
Deck Thrus) with no audio interruption.
If the SL 4 is not powered by the universal
power supply when Scratch Live is launched
(USB connected), the Deck Thrus will be off, but
can be turned on in Scratch Live.
To turn the Thrus off and on in Scratch Live,
click on the THRU button just above each Virtual
Deck for the respective channel. This will change
the state of the channels to Thru Mode, sending
audio direct from the SL4 inputs to your mixer.

If external power is connected, the device is self-
powered and power is not used from either USB
port.
If external power is not connected, the SL 4
draws power from USB A port if available and
then from the USB B port if there is no power
from USB A. Power switching is automatic and
the SL 4 operates uninterrupted as long as one
of the three possible power sources is available.
If computers are added and removed from the
two USB ports for DJ hand-over, it is best to have
external power connected to cover the case
when both USB ports are briey disconnected.
External power is not required if users ensure
that at least one computer is left connected at all
times. See “tWO cOmputeR cOnnectiOn” On

pOWeR SuppLy
Connect the barrel connector of the power
supply to the 7.5 VDC jack on the SL 4. Plug the
power supply into an AC outlet.
The universal power supply includes different
input plugs for the USA, Europe, UK and
Australia. The USA plug is attached at the factory
—you may need to replace it in your country.
To remove a plug,
PUSH the button while
turning the outer rim
counterclockwise.
To attach a plug,
rotate it to t into
the supply and turn
clockwise until it locks
in place.
The power supply is regulated 7.5 volts
DC, 1 amp, using a P6 type barrel plug. Any
substitute must meet these specications.

The SL 4 is a dual personality device. When
using Serato Scratch Live, proprietary Serato
Audio Research drivers are used in place of
Rane ASIO (Windows) and Core Audio (Mac)
drivers. The included Rane drivers are used
when Scratch Live is not running.
The SL 4 has two USB ports, allowing
simultaneous connection of two computers.
Each port is completely independent. It is
possible to run Scratch Live using proprietary
drivers on one port while running third party
software using ASIO or Core Audio on the other,
in any combination.
Rane ASIO and Core Audio drivers allow
the SL 4 to act as a 10-in 10-out external USB
sound card for use with multiple third-party
software applications supporting Core Audio or
ASIO. These drivers are multi-client, meaning
they allow multiple applications on a computer
to share the device at the same time.
ASIO and Core Audio drivers are not available
on a machine while Scratch Live is running. To
use multi-client ASIO or Core Audio drivers with a
third-party application while using Scratch Live,
you can connect two computers to the SL 4 with
one running Scratch Live and the other running
ASIO or Core Audio application(s). Connecting
both USB ports to the same machine is not
recommended.
The ASIO and Core Audio drivers are included
in the Scratch Live installer as an option. The
option to install them is checked by default.

The SL 4 uses a low-latency, multi-client,
ASIO device driver to interface with software
applications other than Scratch Live on
Windows operating systems. Multi-client ASIO
allows different audio software applications to
simultaneously stream audio to and from the
SL 4. If the same playback channel is selected
in more than one application, the driver mixes
the audio from the different applications before
streaming it to the device.
The driver Control Panel may be launched
from the Windows Control Panel. Select Start >
Control Panel > Rane SL4.
