Outboard gear

Outboard gear is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Outboard gear rather than just read about it. In short: Musical outboard equipment or outboard gear is used to process or alter a sound signal separately from functionality provided within a mixing console or a digital audio workstation. Outboard effects units can be used either during a live performance or in the recording studio.

Key takeaways

Outboard gear belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Outboard gear to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Outboard gear from memory before moving on to harder problems.

Reference excerpt

Musical outboard equipment or outboard gear is used to process or alter a sound signal separately from functionality provided within a mixing console or a digital audio workstation. Outboard effects units can be used either during a live performance or in the recording studio.

Overview Some outboard effects units and digital signal processing (DSP) boxes commonly found in a studio are:

analog-to-digital and digital-to-analog converters musical instrument digital interfaces (MIDIs) microphone preamplifiers equalizers dynamics effects units: compressors/limiters, noise gates time-based effects units: reverb, flanging, delay, chorus etc.

Devices The term outboard was originally used to describe a piece of audio equipment that existed outside of a studio or venue's primary analog mixing board. Today, analog effects are also considered outboard when used in conjunction with console-free computer-based digital recording systems. Famous examples include analog dynamic range compressors, such as the Teletronix LA-2A and the Universal Audio/UREI 1176, early multi-effects units like those made by Eventide, and physical or digital reverb processors invented by EMT and Lexicon.

Vocal effects Some units either introduce a reverberation effect or some kind of pitch transformation or coloration of the singer's voice. Digital units have been designed that can compress or expand the duration of sound; these alter the speed of length of the original sound.

Digital units The invention of the MIDI interfaced electronic keyboard has seen a leap forward in the way that the sound of musical instruments is produced on stage or in the recording studio. The modern keyboard produces digital signals when the keys are depressed, these signals are processed by external effects units to reproduce original digitally sampled instrument sounds, such as a classical piano or string and wind instrument. This allows the user of such a device to reproduce the sound of virtually any instrument.

Etymology The term outboard can be considered "out of board" or "not inside the board". When recording engineers / live sound technicians needed an external processor that was not a part of their mixing surface they would go "Outboard".

Worked examples

Example 1 — a first encounter with Outboard gear

Start with the simplest possible case. Write down what Outboard gear claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Outboard gear before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Outboard gear ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Outboard gear

In research: Outboard gear appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Outboard gear in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Outboard gear is common in secondary-school and first-year university syllabi. It links to neighbouring topics Audio effects, Digital signal processing, Effects units, so understanding it makes those chapters shorter.
In everyday life: Look for Outboard gear outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Outboard gear in simple terms?

Why does Outboard gear matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Outboard gear?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
