PLug and Play

You don’t need any special ‘Wharfedale Pro’ driver software to make an SL mixer work perfectly with a Windows, Mac or Linux computer.  

Simply connect the SL mixer to the computer with the USB cable and, because the mixer is a ‘Class Compliant’ USB audio device, it will simply use the internal driver software of your host computer.  With the mixer connected and turned on, just select the USB audio driver in your system settings/device manager and suddenly you’ve got a digital audio connection to and from your computer.

2-channels into the computer and 2-channels out.  All over the supplied USB cable.  

Musical eq

 

An ultra musical 3-band EQ is available on all channels, with dedicated FX send and auxiliaries.

USB Audio Interface

 

With a built-in USB audio interface, the SL series enables a stereo in/out which can be used for playback of audio files from your PC or Mac, and can also record the master output of your mixing desk. 

16-bit / 48 kHz recording ensures 2-channel CD quality audio, whether working in a live or studio environment.

16 Digital FX

SL824USB and SL1224USB feature the FX logic DSP processor which delivers a total of 16 effects. These include a variety of delays, reverbs, chorus, and rotary speaker algorithms, achieving a professional touch on your mix and lending itself to more creative sound engineering styles.

By name, the 16 FX are……

(1)Hall1 (2)Hall2 (3)Room1 (4)Room2 (5)Room3(6)Plate reverb1 (7)Plate reverb2 (8)Plate reverb3 (9)Chorus (10)Flange (11)Delay1 (12)Delay2 (13)Chorus/Room1 (14)Chorus/Room2 (15)Bypass (16)Rotary speaker.

All very useable, in the real-world!

AC power

SL series do not use a ‘wall wart’ external power supply.  The AC cable is included and the internal transformer ensures smooth power delivery to the internal electronics.
