Introduction Congratulations on purchasing the Samson S83/S63 Mixer Amplifier! In this manual, we’ll take you on a guided tour through all the features of this powerful and flexible device, and we’ll tell you how to get the most out of the S83/S63. Although designed for easy operation, we suggest you take some time out first to go through these pages so you can fully understand how we’ve implemented a number of unique features. The S83 and S63 both combine a flexible multi-channel mixer with a

S83/S63 Features The Samson S83/S63 utilizes state-of-the-art technology in integrated mixer/amplifier design. Here are some of its main features: • Standard 19” rack-mount design (taking just four rack spaces) allows the S83 and S63 to be easily integrated into any setup. • Multiple channels (eight in the S83; six in the S63) and mic and line inputs for each channel allow you to blend together a variety of source signals, including dynamic or condenser microphones, keyboards, CD/tape players, e

S83/S63 Features • A phantom power switch enables you to use the S83 and S63 with high- quality condenser microphones. When turned on, 48 volts of phantom power is provided to the mic connectors of all input channels. • Protection relay circuitry prevents “thumps” when powering on or off. This means that you can use the S83/S63 with a single power strip into which other audio devices are connected, without danger of damage to connected speakers. • A rear-panel amplifier input allows you to br

Connecting The S83/S63 - General Suggestions The actual connections you’ll make to and from the S83/S63 will vary according to the environment you use it in and the particular equipment you have. However, here are a few basic rules concerning connections that will apply in pretty much all situations: • In general, it’s best to make all connections with the S83/S63 turned off— this particularly applies to speaker connections. If you must make connec- tions with the power on, make sure that the

Setting Up and Using the S83/S63 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 any standard 19” rack, requiring four rack spaces. Be careful when handling the S83/S63—the rear heat sink fins and side rack panels have sharp edges. Make sure that the rear heat sink fins are unobstructed and that there is good ven

Setting the Correct Gain Structure You’re now ready to establish the correct gain structure—the key to getting the best performance from the S83/S63, or from any mixer, for that matter. This is a simple procedure that ensures optimum input and output levels so that no unnecessary noise (caused by too low a signal) or overload distortion (caused by too high a signal) is created. Here’s a step-by-step description of how to do so: a. With all connections made (as described above) but with the po
