Samson PL1602 manual Setting the Correct Gain Structure

Setting the Correct Gain Structure

j.If you have any outboard signal processors connected to the Aux send and return jacks on the rear panel, follow this step. Because outboard effects processors can sometimes be quite noisy, it’s particularly important to maximize the amount of signal being sent to them via the PL 1602 Aux sends. The idea is to drive these devices as hot as possible (short of overloading them) and then to use the corresponding Aux return level to carefully adjust the amount of processed signal being blended with the dry signal. To set optimum Aux send levels, use a channel that has already had its gain structure adjusted in step (g) or (i) above. Turn both Aux send knobs for that channel to their “0” (unity gain) position (bear in mind that, when a pair of channel inputs are connected, the odd-numbered [left] input signal can only be routed to Aux 1L, while the even-numbered [right] input can only be routed to Aux 2R; when only the odd- numbered [left] input is connected, the signal can be routed to both Aux 1L and Aux 2R). Then play the instrument (or sing into the microphone) connected to that channel. Adjust the input levels of connected outboard effects processors so that their meter shows incoming signal normally in the 0 vu range (with only occasional higher excursions). Finally, optimize the Aux return levels: While continuing to play your instrument (or continuing to sing into the microphone), slowly raise each Aux return level control until you hear the desired amount of processed signal added to the dry signal. For more information, see the “Using the Aux Sends and Returns” section on page 18.

k.The gain structure is now correctly set— you’ve optimized the level of all signals coming into and out of the PL 1602, and the end result will be minimum noise and distortion and maximum clean sound. You’ll now find that the majority of your mixes can be accomplished with the Left/Right faders at their “0” position and with most channel Level controls at or near their 2 o’clock “0” (unity gain) position). If you need to make adjustments to the overall level, use the level control of your power amplifier.
