RANE SL2 FOR SERATO SCRATCH LIVE • OPERATOR’S MANUAL 2.4.4
Playing Regular Vinyl and CDs
NOTE: the SL2 must be powered by
USB or the optional external power
supply for the DECK THRUs to work.
If external power is connected, the SL2
is self-powered and power is not used
from the USB port.
If external power is not connected, the
SL2 draws power from the USB port.
Power switching is automatic and the
device continues to operate uninterrupted
as long as a power sources is available.
If you wish to use the SL2 Thru outputs
when a computer is not connected,
you will need to obtain and connect the
optional external power supply. Thrus are
turned on and off in the Control Panel.
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 SL2 inputs to your mixer.
See “Thru Mode” on page 16.
Optional Power Supply
The Rane RS 6 power supply is an
accessory for the SL2. Customers in the
U.S.A. may purchase from the Factory
Store at www.rane.com. Customers in
other countries may purchase the RS 6
from the International Distributor in your
country, which are listed at
rane.com
.
Connect the barrel connector of the
power supply to the 7.5 VDC jack on the
SL2. Plug the power supply into an AC
outlet. The yellow POWER indicator will
light on the SL2.
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 fit 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
specifications.

USB Drivers
The SL2 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.
Rane ASIO and Core Audio drivers
allow the SL2 to act as a 4-in 4-out
external USB sound card for use with
multiple third-party software applications
that support Core Audio or ASIO. ASIO
and Core Audio 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 when
Scratch Live is running.
The ASIO and Core Audio drivers are
included in the Scratch Live installer as an
option. See the instructions in “Installing
Scratch Live” on page 8.
ASIO (Windows)
The SL2 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 SL2. If the
same playback channel is selected in
more than one application, the driver
mixes the audio from 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 SL2
.
Core Audio (Macintosh)
The SL2 uses a low-latency, Core Audio
device driver to interface with software
applications other than Scratch Live
on Macintosh operating systems. Core
Audio allows different audio software
applications to simultaneously stream
audio to and from the SL2.
To launch the SL2 driver Control Panel,
open the System Preferences window.
Locate the SL2 in the “Other” section and
click the SL2 icon.
Control Panel
The Driver Control Panel supports:
•
Analog Pass Thru
check boxes allow
stereo outputs 1-2 to select USB
playback (computer) or analog input
(vinyl or CD) as their source. If a button
is on, USB playback is disabled and the
SL2 input is fed to the output.
•
Sample Rate
radio buttons allow a user
to select a sample rate of 48 kHz or 44.1
kHz.
•
Phono / CD
read-only indicators show
the Phono or CD input switched on the
SL2.
•
Buffer Size
increases or decreases the
USB driver buffer size. The SL2 drivers
run very reliably at latencies below
8 milliseconds. However, computer
performance and available resources
(number of apps running) may adversely
affect streaming audio. If pops and
clicks are heard in USB audio, try
increasing the buffer size. In ASIO, total
round-trip latency = buffer size + device
latency. In Core Audio, total round-
trip latency = buffer size + software
application l device latency. SL2
latency is 1.3 ms at 48 kHz and 1.4 ms
at 44.1 kHz.
• If the SL2 firmware on your computer
is newer than installed in your SL2,
the Update Device Firmware panel is
enabled. Pressing the
Update Firmware
button updates the SL2 firmware to the
newer version installed with your driver.
