1. INTRODUCTION Your S-16 is the "big brother" of one of the most popular and best selling mixer in the world, S-8, that has been sold already in terms of thousands of units worldwide. Despite its compact dimensions, great performances and sound quality are insured thanks to the specification of the components used and the building quality.
2. FEATURES The S-16 16-Channel Mixing Console is designed for the professional application, and presents with the following specific features: . Ultra-low noise 16-channel 2+2-bus mixing console . 8 MIC input channels with gold-plated XLRs and phone connectors . 4 stereo input channels with balanced TRS jacks . 2 stereo AUX returns for additional functionality . Ultra-low noise discrete MIC preamps with +48V Phantom power . Independent main mix, control room and headphone outputs .
3. GETTING STARTED 3.1 Please check the AC Voltage available in your Country before connecting your S-16 to the AC socket. 3.2 Be sure that the main power switch is turned off before connecting the Mixer to the AC socket. Also, you should make sure that all Input and Output Controls are turned down. This will avoid damages to your speakers and avoid excessive noise. 3.3 Before turning on the S-16 you shall connect it to a power amplifier and turn-on the mixer BEFORE the power amplifier.

4.13 PEAK 18 Inside your S-16 the audio signal is monitored in several different stages and then sent to the PEAK Led. When this Led blinks, it warns you that you are reaching signal saturation and possible distortion. The PEAK Led will blink with a level that is 6dB before actual clipping. 4.14 FADER 19 This Fader will adjust the overall level of this channel and set the amount of signal sent to the Main output. 4.15 INSERT 20 Insert points are provided for the Mono Mic Channels.
-. AUX SEND 25 26 The both switches are used to determine the master AUX SEND levels. The adjustable range is from - to +15dB. When the effect unit connected to mixer has no input gain control, you can get a further +15dB gain available from these AUX SEND outputs. 0 2 1 - The EFX TO AUX1 button is used to swtich the signal from AUX RETURN 2 between MAIN MIX and AUX SEND 1.
30 -. ALT 3-4 This control is used to adjust the level of the ALT output, and the adjustable range is from - to +15dB. This is another way to offer you an extra independent stereo submix with its own level adjustment knob. -. POWER 31 This LED indicates when the Power is on in your S-16. -. PHANTOM 32 This LED indicates when the Phantom Power is switched on. -.
4.17 REAR PANEL 37 -. AC INLET & FUSE HOLDER Use it to connect your S-16 to the Main AC with the supplied AC cord. Please check the Voltage available in your Country and how the Voltage for your S-16 is configured before attempting to connect your S-16 to the Main AC. 38 2 POWER PHANTOM ON OFF 38 Use only with a 250V fuse -. POWER Apparaten skall anslutas till jordat uttag nar den ansluts till ett natverk This switch is used to turn the Main Power ON and OFF. 37 AC INPUT -.
5. INSTALLATION & CONNECTION Ok, you have got to this point you are now in the position to successfully operate your S-16. However, we advise you to read carefully the following section to be the real Master of your own Mix. Not paying attention enough to the Input signal level, to the routing of the signal and the assignment of the signal will result in unwanted distortion, a corrupted signal or no sound at all.
B. Wiring Configuration You can connect unbalanced equipment to balanced inputs and outputs. Simply follow these schematics.
Ring=Return Signal (Connected together) To Channel Insert Sleeve=Ground/Screen Tip=Signal To Tape or FX Input Sleeve=Ground/Screen 'Tapped' Connection Direct Output Lead (Enables the Insert to be used as a Direct Output while maintaining the channel signal flow) To Processor Input Sleeve=Ground/Screen Tip=Send Signal Tip To Channel Insert Sleeve Ring=Return Signal Ring To Processor Output -Stereo lead for insert Connection (To be used when the processor does not employ a single jack connection
6. FOR THE EXPERTS WHO WANT TO KNOW MORE As we have told you previously in this Manual, the Aux Send 2 Control both on Mono and on stereo channels is factory wired as POST-FADER. If you have some skill in electronic components soldering you can modify this setting and have all your AUX sends configured as PRE-FADER.
