Machine Heads

A tuning mechanism for stringed instruments (bass guitar pictured), to set the pitch of each string by either increasing or decreasing string tension.
Chladni Plate

An acoustics demonstration – where grains of salt collect at the nodes (points of no movement), when the plate is vibrated – nodal patterns vary according to the excitation frequency.
Isolation Spring

Isolation spring – an assembly designed for low frequency vibration mitigation, used for equipment or floors.
Graphic Equalizer

Analog 1/3-octave graphic equalizer – enables adjustment of an audio signal’s tonal balance at ISO center frequencies – this model is unconventional with rotary amplitude controls (vs. faders).
Headphones

Reference headphones – the reference designation indicates an extremely accurate, detailed, wide-band response — and produce a very natural sound quality.
Video Displays

Video display array – setup for simultaneously monitoring of numerous video sources and destinations.
Console Faders

Audio faders (log taper variable resistors/slide potentiometers) provide adjustable signal attenuation for each channel’s audio signal.
Microphone Windscreen

Component of a microphone capsule, which diminishes the affect of plosives (aka oral stop of consonants), as well as actual wind.
Oscilloscope

Measures and displays amplitude (V) versus time (H) of electronic signals when applied to either of the two input channels (aka o-scope).
Vibration Control

Vibration control products – three rubberized models for specific vibration isolation applications.
Integrated Circuit

Integrated circuit (aka chip or IC) and resistor components populate a custom printed circuit board (PCB) for an audio monitoring and control application.
Potentiometer

Potentiometer (aka pot) – a variable resistor typically used to adjust a voltage level (soldered in a custom audio PCB, next to an LED).
Real Time Analyzer

RTA display – measures, displays and stores the amplitude versus frequency of an audio signal, typically captured via a calibrated microphone.
Speaker Cone

A diaphragm – often fabricated from paper, cloth, plastic, aluminum, mylar or polypropylene – is designed to couple the pistonic motion of the voice coil to the air, driven by an amplified audio signal.
Reference Microphone

"Reference" indicates an accurate, calibrated model for acoustical analysis, test and measurement. It generally features an omnidirectional pattern and condenser design.
Tone Arm Gimbal

Gimbal assembly – provides the pivot point for a turntable’s tone arm, as well as weight and anti-skating adjustments, from days of vinyl records.
High-frequency Driver

High-frequency driver – a transducer component of a playback system which extends the upper limit of the frequency response range.
Speaker Components

Internal components attached to the speaker cone – a voice coil, former and spider – are joined together with lightweight adhesives, and move with cone vibration.
Drum

A hit from a stick or beater vibrates the head (circular membrane) in a complex modal pattern, with pitch determined by the head's diameter, tension and mass.
Waveforms

A graphic depiction of sound propagation through a medium, as alternations of high and low pressure.
