Introduction S TUDIO 24 R EFERENCE M ANUAL 1 3 F OR 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 24 Recording Console. The Studio 24 follows commonly-accepted traditions for signal levels and routing.
Introduction 1 4 S TUDIO 24 R EFERENCE M ANUAL Think of them as an AUX 1/2 send with independent input source selection from the channel source, which can be submixed into the L/R if desired. EQ: The 75 Hz high-pass filter switch is independent of the EQ and may be used even if the EQ IN switch is out.
Introduction S TUDIO 24 R EFERENCE M ANUAL 1 5 A BOUT THE S TUDIO 24 The Studio 24 is an extremely flexible, 12-channel, 24-input, 2-group plus L/R output, in-line monitor professional audio mixing console.
Introduction 1 6 S TUDIO 24 R EFERENCE M ANUAL provides insert points on Channels 1 - 8, both Groups and the stereo main outputs, for use with compressors and graphic equalizers. Control room monitoring is made simpler by stereo-in-place Solo on each main channel.

Introduction 1 8 S TUDIO 24 R EFERENCE M ANUAL T HE 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 a part at a time and built up in layers.

Introduction 2 4 S TUDIO 24 R EFERENCE M ANUAL A UX S ENDS AND R ETURNS : E FFECTS 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 S TUDIO 24 R EFERENCE M ANUAL 2 5 C HAPTER 2: G UIDED T OUR R ECORDER M IX /M ONITOR M IX S YSTEM The Studio 24 is designed to accommodate the two-way signal flow required in a recording console. The recorder and monitor mix systems are where signals are mixed, EQ’d and routed to the Aux sends, Groups and Left and Right Master outs.
Guided Tour 2 6 S TUDIO 24 R EFERENCE M ANUAL — and two paths that the audio signal can take: the main channel and the monitor outputs. This is a key concept to understand: the basic principle is that there are three sources of audio and two ways it can go.
Guided Tour S TUDIO 24 R EFERENCE M ANUAL 2 7 The Mid EQ has two knobs: one to set the amount of boost or cut and one to select the frequency you want to control (adjustable from 120 Hz to 13 kHz). To avoid low-end rumble and noise, turn on the 75 Hz high-pass filter, which removes frequencies below 75 Hz at a rate of 18 dB per octave.
Guided Tour 2 8 S TUDIO 24 R EFERENCE M ANUAL M ONITOR 1/2 SECTION In multitrack recording, once signal goes from the Group Outputs to the recorder, it comes back to the tape inputs. The TAPE IN jack has no trim control of its own; it is designed to handle the unbalanced line levels that most multitrack recorders generate.
Guided Tour S TUDIO 24 R EFERENCE M ANUAL 2 9 A UX S END /R ETURN S YSTEM A UX 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.
Guided Tour 3 0 S TUDIO 24 R EFERENCE M ANUAL C ONTROL R OOM S YSTEM The SOLO switches in each channel, along with the Control Room switches and Headphone section, make up the Control Room system of the Studio 24.
