Rane SL2 SL2 Owner's Manual for Scratch Live 2.5.0 - Page 7

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 OPEN OPEN button while turning the outer rim PUSH counterclockwise. To attach a plug, rotate it to fit into the supply and turn clockwise until it locks in place. LOCK LOCK The power supply is regulated 7.5 volts DC, 1 amp, using a P6 type barrel plug. Any substitute must meet these specifications. -(5.5mm) +(2.5mm) 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 SL 2 Audio Driver Control Panel SL 2 Audio Driver Version: 1.0 Analog Pass Thru Channel 1 Thru Sample Rate 48 kHz Channel 2 Thru 44.1 kHz Phono CD Update device firmware Device firmware version: 1.20 Update firmware - Buffer Size 50 45 40 35 30 25 20 15 10 5 1 14 ms 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 roundtrip latency = buffer size + software application latency + 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. RANE SL2 FOR SERATO SCRATCH LIVE • OPERATOR'S MANUAL 2.5.0 7
