Introduction Studio 32 Reference Manual 9 For the experienced: a quick overview If you're already familiar with mixing consoles, here are some important points you need to know about the Alesis Studio 32 Recording Console. The Studio 32 follows commonly-accepted traditions for signal levels and routing.
Introduction Studio 32 Reference Manual 10 About the Studio 32 The Studio 32 is an extremely flexible, 16-channel, 4-group plus L/R output, in-line monitor professional audio mixing console.
Introduction Studio 32 Reference Manual 11 Basic Principles of Mixing & Multitrack Recording Source select, level control, and destination assignment When it’s being used in a recording studio, .
Introduction Studio 32 Reference Manual 12 The stages of multitrack recording Most multitrack recording is a three-stage process. Instead of recording an entire musical group in a single take of a live performance, recordings are usually made one instrument at a time and built up in layers.
Introduction Studio 32 Reference Manual 13.
Introduction Studio 32 Reference Manual 14 The different mixes and what they’re needed for Now that you understand the different sources and different destinations used during the three stages of the multitrack recording process, let’s look at each one individually, without the other components getting in the way.
Introduction Studio 32 Reference Manual 15 EQ IN MUTE PAN FADER DIRECT OUT GRP 1/2 GRP 3/4 L/R (to MON 1/2 SOURCE) (Post-EQ to MON 1/2 SOURCE when MIC/LINE is selected at both) GROUP OUTPUTS (combined.
Introduction Studio 32 Reference Manual 16 Monitor (Control Room) Mix This mix is what the engineer and/or performer hears in headphones or the control room speakers. During overdubbing, this mix is typically controlled by the Studio 32’s MONITOR 1/2 section, and sometimes by the L/R mix.

Introduction Studio 32 Reference Manual 18 Aux Sends and Returns: Effects The last important mix is usually used for adding effects (such as reverb, delay, chorus, etc.) to the mix. This may be part of the tracking and overdubbing stage, and is almost always part of the mixdown stage.
Guided Tour Studio 32 Reference Manual 19 C HAPTER 2: G UIDED T OUR Recorder Mix/Monitor Mix System The Studio 32 is designed to accommodate the two-way signal flow required in a recording console. This is where signals are mixed, EQ’d and routed to the Aux sends, Groups and Left and Right Master outs.
Guided Tour Studio 32 Reference Manual 20 important to set this level properly, since high levels could lead to distortion and levels set too low will cause noise (see Setting Levels ).
Guided Tour Studio 32 Reference Manual 21 Group mix: Once signals are routed to the Group section, you can use the GROUP FADERS to determine the total volume of all channels assigned there. In the studio, the Group output usually is connected to the inputs of a multitrack recorder, such as the Alesis ADAT.
Guided Tour Studio 32 Reference Manual 22 Aux Send/Return System Aux sends In the center of each channel module are the blue knobs that make up the Auxiliary Send section, which allows the signal to be routed to outboard signal processing equipment. There are two Aux knobs in each channel, but there are four different Auxiliary Masters and outputs.
Guided Tour Studio 32 Reference Manual 23 Control Room System The SOLO switches in each channel, along with the Control Room switches and Headphone section, make up the Control Room system of the Studio 32.

Hooking It Up Studio 32 Reference Manual 25 C HAPTER 3: H OOKING I T U P Unpacking and Inspection Your Studio 32 was packed carefully at the factory, and the container was designed to protect the unit during shipping. Please retain this container in the highly unlikely event that you need to return the Studio 32 for servicing.
Hooking It Up Studio 32 Reference Manual 26 Power Make sure you read the initial Important Safety Instructions chapter at the front of this manual. The Studio 32 works with a single standard line voltage and comes with a detachable AC line cord suitable for the destination to which the mixing console is shipped.
Hooking It Up Studio 32 Reference Manual 27 Avoiding ground loop noise In today’s studio, where it seems every piece of equipment has its own computer chip inside, there are many opportunities for ground loop problems to occur.
Hooking It Up Studio 32 Reference Manual 28 Channel Inputs and Outputs Each of the 16 channel modules on the Studio 32 contains an XLR balanced MIC IN connector, a 1/4" TRS balanced LINE IN jack, a 1/4" TRS balanced TAPE IN jack, a balanced 1/4" TRS DIRECT OUT jack, and a 1/4" TRS INSERT jack.
Hooking It Up Studio 32 Reference Manual 29 1/4" plug, balanced line sources may also be connected here using a “stereo” TRS plug as shown above. Line inputs may also be used for connecting additional effects returns, where additional post-effect equalization is required.
Hooking It Up Studio 32 Reference Manual 30 Insert The INSERT connector is a TRS 1/4" jack which consists of an insert send (the tip of the TRS plug) and an insert return (the ring of a TRS plug).
Hooking It Up Studio 32 Reference Manual 31 Master Inputs and Outputs Along the top of the back panel above the master section of the Studio 32 you’ll find most of the connectors that provide the outputs of the console: two 1/4” MAIN OUT connectors (plus two MAIN INSERT jacks), and four 1/4" GROUP OUT connectors.
Hooking It Up Studio 32 Reference Manual 32 Stereo Aux Returns The STEREO AUX RETURNS are eight balanced 1/4" line input jacks that are most often used to connect to the stereo outputs of four external effect units. However, these may also be used as additional inputs for stereo sound modules, samplers or synthesizers, if desired.
Hooking It Up Studio 32 Reference Manual 33 Chart of Connections The Studio 32 may be easily interfaced with most other professional recording and audio equipment. All inputs and outputs, with the exception of the microphone inputs, use 1/4" jacks, and may be used with balanced or unbalanced circuits.
Hooking It Up Studio 32 Reference Manual 34 Connecting to an Unbalanced -10 dBV Multitrack Recorder Interfacing the Studio 32 with a typical multitrack recorder using semiprofessional unbalanced phono or 1/4" phone jacks is a simple process.
Hooking It Up Studio 32 Reference Manual 35 Connecting to a Professional +4 dBu Multitrack Recorder Professional recorders typically feature 3-pin XLR connectors on their inputs and outputs. ADATs feature a multipin ELCO connector that takes care of all the channels (8 inputs, 8 outputs) on a single connector.
Hooking It Up Studio 32 Reference Manual 36 Connecting to a 2-Track Mixdown Deck The mixdown deck is where everything comes together: the final mix. This is your stereo master recording of the finished project (or a rough mix of a work in progress).
Hooking It Up Studio 32 Reference Manual 37 Connecting to a Control Room amplifier Connect the Studio 32’s Control Room L & R Outs to the inputs of the amplifier used for the control room monitor speakers. The CONTROL ROOM knob on the Studio 32 controls the level of the control room monitor speakers.

Effects and Signal Processing Studio 32 Reference Manual 39 C HAPTER 4: E FFECTS AND S IGNAL P ROCESSING Connecting Aux Sends and Returns to Outboard Effects Aux Sends 3 through 6 are derived post-fader, which means that any changes in level in the fader will also cause a change in level at these as well.
Effects and Signal Processing Studio 32 Reference Manual 40 Should you use one or two inputs to effects? ✪ If your effect unit has two inputs, in most cases you only need to connect from ONE Aux Send to the LEFT (mono) INPUT of the effect unit, but you will still connect both the LEFT and RIGHT OUTPUTS of the effect to the Stereo Aux Return.
Effects and Signal Processing Studio 32 Reference Manual 41 Channel’s MUTE button, either). As you change fader levels, you may need to make corresponding adjustments to MON 1 and 2 in order to maintain the desired balance between dry and effected signal.
Effects and Signal Processing Studio 32 Reference Manual 42 In a typical installation, Aux 4 is used for effect sends from the channel. • To send signal from the monitor and the channel to the same effect device(s) , press the AUX SOURCE button down and press the TO 5/6 switch.
Effects and Signal Processing Studio 32 Reference Manual 43 To hear effects in the headphone/cue mix: Often while recording, musicians would like to hear some reverb or delay in their headphone mix. It is possible to meet this need without actually recording the effect.
Effects and Signal Processing Studio 32 Reference Manual 44 Connecting Signal Processors to Insert Jacks Inserts are used to connect signal processing devices directly into the signal path of a Channel.
Recording Studio 32 Reference Manual 45 C HAPTER 5: M ULTITRACK R ECORDING A PPLICATIONS Recording Setting Levels Your job as operator is to set the audio levels in order to ensure the cleanest signal with the least amount of background noise (hiss or hum).
Recording Studio 32 Reference Manual 46 If a large amount of EQ is used, it may become necessary to decrease either the TRIM control, or the Channel FADER, or both. The EQ is capable of adding quite a bit of gain and is a frequent cause of overload distortion problems.
Recording Studio 32 Reference Manual 47 How to Record a Single Source to One Track When recording a single source appearing on one Channel onto a single tape track, it is usually best to use the DIRECT OUT of the Channel. This provides the most direct connection between the Studio 32 Mixer and the multitrack.
Recording Studio 32 Reference Manual 48 Recording Multiple Sources to One Track When more than one Channel is to be recorded onto the same track of a multitrack recorder, it is necessary to assign all desired Channels to a Group, and connect the Group Output jack to the input of the multitrack.
Recording Studio 32 Reference Manual 49 Recording Multiple Sources to Two Tracks (Stereo) Recording multiple sources onto two tape tracks is simple--you just use two Groups. Pan hard left all channels going to the odd-number Group, and pan hard right all channels going to the even-number Group.
Recording Studio 32 Reference Manual 50 Recording Tips For the cleanest possible recording, the Group FADERS (or Channel FADERS if the DIRECT OUTS are being used) should be adjusted so that the level .
Recording Studio 32 Reference Manual 51 Overdubbing Using MONITOR 1/2 to Monitor the Multitrack Once you have recorded onto the multitrack tape machine, you’ll need to hear the playback of those tracks, as you record new tracks in sync with the material already on tape (see next section, Getting the Mix to Headphones ).
Recording Studio 32 Reference Manual 52 Using the Channel Faders to Monitor the Multitrack If you’re only recording a few inputs at a time, you may want to use a different technique for monitoring. Monitoring on the channel faders gives you a head start on your mixdown, and also allows you to start using the parametric EQ.
Recording Studio 32 Reference Manual 53 Once you have the tape tracks returning to the mixer, it is simple to create a cue mix for the musicians to listen to over headphones while overdubbing. The cue mix is created using MONITOR 1/2 on the Studio 32, because it is a pre-fader mix that is independent from all other mixes.
Recording Studio 32 Reference Manual 54 defined. , Connecting to a Headphone Amp ). In this case, the MONITOR 1/2 MASTER control will set the overall level going to the headphones.
Recording Studio 32 Reference Manual 55 Monitoring MIDI Virtual Tracks If you are using a MIDI sequencer, the tracks being played “live” from sound modules in synchronization with the tape are effectively the same as additional tracks on tape –– which is why they are called “virtual tracks.
Recording Studio 32 Reference Manual 56 Bouncing Tracks Sometimes it is necessary to combine several tracks onto another track, particularly when you are running out of tape tracks.
Recording Studio 32 Reference Manual 57 To bounce multiple tracks to two tracks (stereo): 1 For each Channel (tape track) you wish to bounce, press the FADER SOURCE button so it is down. This sends the tape tracks to the Channel (long) FADERS. 2 Assign the Channels to Groups 1 and 2 by pressing the 1/2 buttons next to the channel faders.
Recording Studio 32 Reference Manual 58 Playback/Mixdown Getting the Mix to the 2-Track Deck Once you have established a satisfactory mix, it’s time to get it over to the tape deck. This involves connecting the L/R MAIN OUT jacks to the mixdown tape deck’s left and right inputs.
Recording Studio 32 Reference Manual 59 Guidelines for a rough mix Creating a mix is easy; creating a great mix (one that jumps off the tape) is a lot harder. There are those engineers who are in demand just for mixing because of their sense of balance between instruments causes the mix to come alive with excitement.
