PARALLEL VS. SERIAL

The MX300 can be used as both a Parallel and Serial (in-line) effects processor.

Typically, reverbs and delays are used in parallel, compressors and de-essers in serial,

and modulated effects can be used in either configuration, depending on the desired

application.

A Parallel Processor is connected by sending a copy of a signal (such as from an Aux

Send of a mixer channel) to an effects device (such as the MX300), and the effected

(or wet) signal is returned to the mixer or amp. It is then blended together with the

original unaffected (dry) signal. This blend is called the Wet/Dry mix. This connection

is most often used for reverbs, delays, and some modulated effects (such as chorus).

A Serial Processor is connected by sending the entire signal through the effects device

and then to an amplifier or mixer, and is not blended with the unaffected (dry) signal.

This is the type of connection most often used for a compressor, de-esser, equalizer, and

many modulated effects (such as tremolo, vibrato, and rotary).

reverbs

Reverberation (or “reverb” for short) is the complex effect created by the way we per-

ceive sound in an enclosed space. When sound waves encounter an object or boundary,

they don’t just stop. Some of the sound is absorbed by the object, but most of the sound

is reflected or is diffused. In an enclosed space, reverb is dependent on many features of

that space, including the size, shape and the type of materials that line the walls. Even

with closed eyes, a listener can easily tell the difference between a closet, a locker room

and a large auditorium. Reverb is a natural component of the acoustic experience, and

most people feel that something is missing without it.

Hall Reverbs - Stereo

SMALL HALL, LARGE HALL, VOCAL HALL, DRUM HALL

A Hall reverb is designed to emulate the acoustics of a concert hall – a space large

enough to contain an orchestra and an audience. Because of the size and character-

istics, Halls are the most natural-sounding reverbs, designed to remain “behind” the

direct sound – adding ambience and space, but leaving the source unchanged. This

effect has a relatively low initial echo density which builds up gradually over time.

Vocal Hall and Drum Hall reverbs are specifically tailored for those uses. Vocal

Hall has as lower overall diffusion which works well with program material that has

softer initial transients like a voice. Drum Hall has a higher diffusion setting which is

necessary to smooth out faster transient signals found in drums and percussion instru-

ments. In addition to general instrumental and vocal applications, the Hall program is

a good choice for giving separately recorded tracks the sense of belonging to the same

performance.

Plate Reverbs - Stereo

SMALL PLATE, LARGE PLATE, VOCAL PLATE, DRUM PLATE

A Plate reverb is a large, thin sheet of metal suspended upright under tension on

springs. Transducers attached to the plate transmit a signal that makes the plate

vibrate, causing sounds to appear to be occurring in a large, open space. The Plates in

the MX300 model the sound of metal plates with high initial diffusion and a relatively

bright, colored sound. Plate reverbs are designed to be heard as part of the music,

mellowing and thickening the initial sound. Plate reverbs are often used to enhance

popular music, particularly percussion.

Room Reverb - Stereo

Room produces an excellent simulation of a very small room which is useful for

dialog and voiceover applications. Room is also practical when used judiciously for

fattening up high energy signals like electric guitar amp recordings.

Chamber Reverb - Stereo

Historically, recording studio chambers were oddly shaped rooms with a loudspeaker

and set of microphones to collect ambience in various parts of the room. Chamber

programs produce even, relatively dimensionless reverberation with little color change

as sound decays. The initial diffusion is similar to the Hall programs. However, the

sense of size and space is much less obvious. This characteristic, coupled with the

low color of the decay tail, makes these programs useful on a wide range of material

- especially the spoken voice, to which Chamber programs add a noticeable increase

in loudness with low color.

Gated Reverb - Mono In/Stereo Out

Gated reverb is created by feeding a reverb, such as a metal plate, through a gate

device. Decay Time is set to instant, while Hold Time varies duration and sound. The

Gated reverb provides a fairly constant sound with no decay until the reverb is cut off

abruptly. This program works well on percussion — particularly on snare and toms;

be sure to experiment with other sound sources as well.
