1. INTRODUCTION Your S-8 is a 8-channel mixer and it is one of the most popular compact mixing consoles in the world. In fact it 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 Your S-8 is provided with 4 mono Line/Mic input, 1 stereo Line/Mic input and an additional stereo Line input to be used with keyboards, Midi Instruments, etc. We have even included a 2-track input/output for recording and playback. Ultra low noise microphone preamplifiers, 3 bands eq on all input channels, pre and post Auxiliary bus and phantom power complete the picture. 5 Input for Microphone and line provided with balanced 1/4" jack and XLR.
3. READY TO START? 3.1 Please check the AC Voltage available in your Country before connecting your S-8 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-8 you shall connect it to a power amplifier and turn-on the mixer BEFORE the power amplifier.

4. CONTROL ELEMENTS 1 4.1 The mono MIC/LINE channels These are Channel 1 through Channel 4. You can connect balanced, low impedance microphones to the XLR socket. On the 1/4" phone jack you can connect either a microphone or a line level instrument. You shall never connect an unbalanced microphone to the XLR socket if you do not want to damage both the Microphone and the Mixer. MIC 1 2 1 3 48 Volt phantom power 4 1 It is available only to the XLR Mic sockets.
5 4.4 STEREO INPUTS These are Channel 5 through 8. They are organised in stereo pair (5&6 pair also features XLR Mic Input) and they are provided with 1/4" TRS phone sockets. LINE IN 5/6 2 LINE IN 7/8 1 5 3 If you connect only the left jack, the input will operate in mono mode. LEFT(MONO) LEFT (MONO) RIGHT RIGHT MIC (MONO) TRIM 0dB 60dB MIC 4.5 The 3 BANDS EQUALISER A 3-band equaliser is provided for all input channels with a wide range of frequency adjustment.
9 4.6 AUX SENDS These two controls will send the audio signal out to Auxiliary busses. AUX 1 is configured as PRE-FADER. It means that the signal is sent out before reaching the main Fader. This will be used for stage monitors. AUX 2 is configured as POST-FADER; therefore, the audio signal will be affected by the Main Channel Fader. This will be used for effects and sound processors. However, Aux 2 can also be configured as Pre-Fader through any internal modification.
4.11 MASTER SECTION 14 - MAIN MIX LEVEL This Control sets the amount of signal sent either to the Main Out socket or to the Tape Output. 15 - LED METER This stereo 12 segments Led Meter will indicate the level of the overall output signal. 16 17 If you push down the 2TK TO CONTROL ROOM button, the 2 TRACK IN signal will be routed into the Control Room output and the level will be adjusted in level by the Control Room knob.
23 STEREO AUX RETURN LEFT(MONO) 2-TRACK IN/OUT AUX SEND RIGHT 1 1 L 22 LEFT 21 RIGHT 2 2 R TAPE IN TAPE OUT 21 - 2-TRACK IN/OUT Input Use the Tape input if you wish to listen to your Mix from a Taper Recorder or DAT, You can assign the signal coming form the Taper Recorder either to a pair of studio monitor using the Control Room assignment on the front panel or you can also send the signal directly to the Main Mix. Output These 1/4" TRS sockets will route the main mix into a tape recorder.

5. INSTALLATION AND CONNECTION Ok, you have got to this point you are now in the position to successfully operate your S-8. 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.
5.1 SOME FINAL TIPS ON 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 Ring=Return Signal 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 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.
