Samson S83 - Manual

Guided Tour - S83 Main Section 1: Meter - This seven-segment bar meter shows the continuous output level ofthe S83. For optimum signal-to-noise ratio, try to adjust all levels (channel andmain) so that program material is usually at or around 0 VU, with occasional butnot steady excursions to the +2 ...

Guided Tour - S83 Rear Panel 1: Power switch - As you may have guessed, this is what you use to turn theS83 on and off. The built-in protection relay circuitry (which mutes the outputsfor approximately five seconds after powering on) prevents power-on “thumping,”which can potentially damage connecte...

1: Level (white) - This knob determines the final signal level being sent bya channel to the main speaker outputs as well as to Effect send 1 (see #2below). In practice, this will be used to adjust the levels of the various signals being blended together by the S63. The “0” position indicatesunity g...

1: Return 1-2 Level (green) - This knob determines the input level of signalarriving via Effects returns 1 and 2 (mixed together in mono). This signal is atunity gain (no boost or attenuation) when the knob set to the 0 position and isboosted when the knob is turned to the right of 0 and attenuated ...

1: Power switch - As you may have guessed, this is what you use to turn theS63 on and off. The built-in protection relay circuitry (which mutes the outputs forapproximately five seconds after powering on) prevents power-on “thumping,”which can potentially damage connected speakers. 2: Fuse holder - ...

16 The actual connections you’ll make to and from the S83/S63 will vary accordingto the environment you use it in and the particular equipment you have.However, here are a few basic rules concerning connections that will apply inpretty much all situations: • In general, it’s best to make all connect...

17 Setting up your S83/S63 is a simple procedure which takes only a few minutes: 1. Remove all packing materials (save them in case of need for future service)and decide where the unit is to be physically placed—it can be mounted in anystandard 19” rack, requiring four rack spaces. Be careful when h...

18 You’re now ready to establish the correct gain structure—the key to getting thebest performance from the S83/S63, or from any mixer, for that matter. This is asimple procedure that ensures optimum input and output levels so that nounnecessary noise (caused by too low a signal) or overload distort...

22 Grounding Techniques Hum and buzz are the biggest enemies you face when interconnecting a large number of different piecesof equipment to a central audio mixer. This is because each piece of equipment may operate at a mar-ginally different voltage (this difference is called potential) and, when t...

23 Using Equalization One of the most exciting aspects to using a mixer such as the S83 or S63 is hav-ing the ability to shape a sound, using a process called equalization. But thereare few areas of sound engineering more misunderstood than equalization, and,just as good EQ can really help a sound, ...

25 Using The Effects Sends and Returns The two Effects sends provided by the S83 and S63 allow you to combine thesignal from multiple channels and send the resulting mix to the rear panelMonitor output jack, to the internal reverb unit, or to external devices such aseffects processors. When an Effec...

26 Using the Monitor Output and Internal Reverb Using the Monitor Output In live performance, it is usually desirable to have onstage monitor speakers that allowthe performer to clearly hear the music being played. Often, however, the performerrequires a different mix than that being sent to the hou...
