1. Mixer Overview
The S/L series mixing consoles are designed for Studio and Live performances. S/L series consoles allow the user to perform
multi-track recording where the tracks equal the number of channels for the mixer; either 24, 40, or 56. This ability is due to the
Dual In-line channel format used on the S/L series. Dual In-line channels provide a mixing path for the microphones or other
input devices to be recorded, a mixing path for the individual channel outputs to a recording device’s inputs and finally a mixing
path for the output of the recording device. Live performances benefit from the S/L’s AUX sends that can be used for monitor
mixes or effects processing.
The SL consoles are equipped with :
• 24, 40, 56 channel frames.
• Low noise mic-pre amps EIN=128dB min.
• 4 band, dual mid sweep, Channel EQ.
• 8 auxiliary sends: 2 pre, 2 pre/post, 2 post, (stereo) pre/post fader.
• 4 stereo returns w/ Aux 1 & 2 sends, pan and level.
• 8 master groups w/ L-R, assignment and pan, mute and solo.
• Comprehensive master control room section with separate studio controls.
• Specially designed high current headphone outputs.
2. Installations

The S/L series console dimensions are in Appendix B for table size and custom installments. A good installation will keep in
mind placement proximity to potential noise sources and positioning the mixer where the sound can be heard clearly from the
audience’s perspective.
The outboard SLP5600 AC power supply is also a consideration when installing a console of this caliber. The AC power for the
mixer and the rest of the sound system needs to first of all, have the capacity to power the system. Be sure power amps and other
high power portions of the system are on large enough and, if possible, separate breakers. It’s possible to lose one or two power
amps in a large system and deal with a 3-6 dB drop in output but if the power amp takes the mixing console with it, you’ve lost
everything. Also, with AC power try to avoid using the same power outlets used by stage lighting. The performance lights typi-
cally require large amounts of power and produce heavy AC power spikes when switched on and off. These lights and many ban-
quet room lights can be on solid state dimmer controllers, which produce noisy spikes on their AC power lines. These noises can
only cause headaches for a sound system and nightmares for a recording studios because some of the spikes are emitted and
can’t be taken out by power conditioners.
The placement of the mixing console in live sound situations is often misunderstood. Especially when a promoter or banquet
director sees the console as taking up valuable floor space or as an eye sore at a fancy show. The placement of the mixing con-
sole is very important in hearing the performance from the perspective of the listeners. The placement for routing cables is fairly
obvious, avoid large power transformers, air conditioners and lighting rigs! Note: the best sound location in a room will be near
the console because that’s where the mix is created.
