Studio Live Consoles Introduction Sound Quality and In-Line Flexibility There are a multitude of considerations that a sound engineer must weigh when choosing the right console. Whether the console will be used for live sound reinforcement or studio recording, ultimately the choice of a console always focuses on sound quality and signal routing flexibility. These were primary design considerations for the new S/L series consoles from Carvin.
) Tape Selection for Buses 5 & 6 and 7 & 8 (depending upon the selection of the Input Tape Switch) allows interconnecting either the tape input signal or the mic input to these buses. Depending upon the configuration of your console, this switch will allow for individual bus routing for quick overdubbing while simultaneously setting up the stereo control room mix.
RECEIVING INSPECTION—read before getting started INSPECT YOUR MIXER FOR ANY DAMAGE which may have occurred during shipping. If any damage is found, please notify the shipping company and CARVIN immediately. SAVE THE CARTON & ALL PACKING MATERIALS. In the event you have to re-ship your unit, the S/L console will only be accepted in our factory designed shipping carton or damage could result in which CARVIN and the shipping company are not responsible for. SAVE YOUR INVOICE.

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.
3. Input Channel section 1. 48V PHANTOM POWER SWITCH This switch provides phantom power for condenser mics in groups of 8 channels. This allows other channel groups to remain non-powered for instruments and dynamic mics that don’t require phantom power. The 48V switch should not be engaged when using sources that do not use phantom power. 2. CHANNEL DIRECT OUT The DIRECT OUT is a 1/4” TRS (Tip/Ring/Sleeve) balanced output.
3. Input Channel section continued. 7. GAIN CONTROL The GAIN control adjusts the gain of the channels high gain microphone pre-amplifier. This pre-amplifier is designed for professional low impedance microphones. Monitor the gain level with the PEAK LED. If the LED is constantly lit, decrease the amount of gain. If distortion is present, decrease your gain until it is eliminated. The GAIN control is also the level control for the LINE IN.
18. CHANNEL AUX 3 AND AUX 4 PRE OR POST SENDS The AUX 3 and AUX 4 level controls (with the Aux 3 - 4 PRE switch in) provides a total of 4 PRE monitor controls when used with AUX 1 and AUX 2 (4 monitor mixes). With the Aux 3 - 4 PRE switch out, AUX 3 and AUX 4 can be used with AUX 5 and AUX 6 as effects sends for a total of 4 post sends. 19. TAPE 5 - 6 SWITCH The TAPE 5 - 6 switch is linked to the TAPE switch at the top of the channel.

In-Line Recording Setup. DIRECT OUT CHANNEL INSERT FADER MIC-PRE MIC TAPE PAD LINE AUXILIARIES The following section describes two of the more common Studio recording setups. These setups are not the only setups you can use, many of the connections described here can be combined and customized to provide the best setup for you. The first Setup is based on the In-Line recording method and the second setup is based on the Split recording method. MASTERS Figure 5-1 5.
Split Recording Setup. The Split recording method has many different looks depending on the mixing consoles setup and features. The basic concept of split recording is simply using a different channel or bus for mixing than was used for tracking. The complication comes with how the features of the mixer are used. If the mixer has direct outputs, then the channel used for tracking goes direct to the recorder’s inputs and another channel is used for the recorders playback through the mixer.
MULTI-TRACK RECORDER FIGURE 5-3 For illustration, the connections have been separated into three parts. This illustration is intended to show the same thing as figure 5-2 with multiple channels.
6. Standard live mixer setups The following section describes aspects of using the S/L console in live sound reinforcement. Because live sound reinforcement is so diverse in set-up requirements and connections, this section will only discuss aspects of a live system setup and focus on the features of the S/L series console.
RECORDING A LIVE SHOW TO 2 TRACK WITH AUX 7/8 For specialty sub mixes, like recording a live show to a 2 track recorder, the S/L consoles feature a stereo send pair. The stereo send pair of AUX 7/8 provides (via the PRE w/ EQ switch down) an independent stereo mix with PAN for live recording. This independent post EQ send allows a completely separate mix to be sent to a 2-track recorder. Use either the AUX 7/8 Sends or the RCA TAPE OUT for the connection of a two track recorder.
SUB MIXING WITH THE GROUPS For live sound reinforcement, the 8 Groups are mainly used for mixing sub groups of channels and providing alternate master outputs for surround sound mixes, center clusters and extension speakers systems. Sub mixing with the Groups is where several channels with a commonality are assigned on the channel to a Group (or Group pair for stereo). Then the Group is assigned to the L-R masters. The advantage is being able to adjust the group with one fader (or two faders for stereo).

7. Using the inserts 15 Full insert The insert jack is a Tip/Ring/Sleeve (TRS) 1/4” phone jack where the tip is the send, the ring is the return and the sleeve is the ground. When used as an insert point or in full insert mode, the channel is opened up to allow an external piece of equipment to be inserted into the channels signal path.

9. SLP5600 power supply .. .. SSLLPP- 5- 5600 600 S/L S/LSeries SeriesPower PowerSupply Supply 10 A M P 120VAC 60Hz 300VA The SL series consoles use the SLP5600 external power supply. The SLP5600 power supply is a two space rack mountable power supply which provides the required DC voltages for the SL series. Power Requirements It is best to supply the SLP5600 with its own dedicated circuit. This reduces possible loss of power to the console if other circuit breakers are over loaded and tripped.
10. Cable connections used on the S/L series console Balanced XLRs are used for the channel MIC inputs, the group outputs and the master left right outputs These all follow the standard: PIN 1 is ground PIN 2 is positive (in phase) PIN 3 is negative (out of phase or inverting) Balanced 1/4” TRS phone jacks are used for the channel direct outputs, the channel tape inputs, and the channel line inputs.

D. Glossary AFL (After Fade Listen) A function that allows the operator to monitor the post-fade signal in a channel independently of the main mix. Assign To route a signal to a particular signal path or combination of signal paths. Attenuate To reduce signal level. Auxiliary Send An output from the console comprising a mix of signals from the channels derived independently of the left, right and group mixes. Balanced A method of connecting audio signals using 3 wires.
Echo The reflection of sound from a surface. Reverberation and echo are terms that can be used interchangeably, but in pro audio a distinction is usually made: echo is considered to be a distinct, recognizable repetition (or series of repetitions) of a word, note, phrase or sound, whereas reverberation is a diffuse, continuously smooth decay of sound. Effects unit An external signal processors used to add reverb, delay, spatial or psychoacoustic effects to an audio signal.
Noise floor will be a quiet hiss, which is the thermal noise generated by bouncing electrons in the transistor junctions. The lower the noise floor and the higher the headroom the more usable dynamic range a system has. Parametric EQ A “fully” parametric EQ is an extremely powerful equalizer that allows smooth, continuous control of each of the primary EQ parameters (frequency, gain, and band-width) in each section independently. “Semi” parametric EQs allow control of fewer parameters.
