Audio & Broadcast Mixing Consoles PSM PTL PTS World-renowned mixing console manufacturers use Bourns® optical encoders and panel controls. For digital mixing consoles, optical encoders such as Bourns® Models EN and EM14 are ideal high-reliability, long-life solutions that can bring years of service to recording engineers and producers alike. For analog mixing consoles, panel controls such as Bourns® Models 51, 81 and 91 provide long-life and low noise, in part due to the superior characteristics of the conductive polymer resistive element design. These controls are typically used for...

Sound Recording and Video Editing Equipment The newest generation of sound recording equipment and video editing stations are digital. These units have a jog-shuttle control that enables the engineer to search through a song or video to a specific point for sound overdubs or for editing purposes. The components used for jogshuttle controls must have a long rotational life and be able to withstand the strain of constant adjustment. Models EN and EM14 are the perfect choice for this application. These components are designed to provide years of reliable service to sound and video engineers....

Electric Guitars and Effect Pedals Electric Guitars 95 Premium 95 Long Bushing 82 Vintage Bourns offers “guitar pots.” For the standard drop-in replacement, Bourns offers the PDB241GTR and long-life PDA24 with knurled or solid shaft. These models are available in an audio or linear taper, and in a variety of resistance values. Recently added are the new “mini” guitar pots; Model PDB181-GTR and PDB183-GTR with a push-pull switch.

Keyboards, Digital Drums and Sound Processors Keyboards and Digital Drums Analog keyboards and synthesizers with hundreds of manual controls are a thing of the past. Bourns offers optical and contacting encoders suitable for use in the new generation of digital keyboards, keyboard controllers and digital drum controllers. Models PES12, PEC11, and ECW are typical discrete components used in keyboards and digital drums. Some keyboard manufacturers may still use low cost panel controls such as Models PDB18, PTV111 and PTV09. PES12 PTV09 ECW PEC11 Sound Processors Industry leaders in the design...

Circuit Protection in Pro Audio Professional audio equipment continues to evolve with designs that incorporate smart features and interconnectivity to computers and other equipment. Power, communication and data ports are found in virtually all state-of-theart audio equipment designs including audio, video and broadcast mixing consoles, digital recording equipment, instrument amplifiers, and sound processors. By incorporating these ports, the internal hardware is much more susceptible to faults from short circuits, electrostatic discharge (ESD) and power surges. Bourns® offers a wide...

Board Level Resistive Components in Pro Audio Trimming Potentiometers Trimming potentiometers are used in adjustment of power supply circuits in all types of professional audio equipment including power amplifiers, powered mixing consoles, sound processors and other peripheral outboard equipment. Bourns offers a wide variety of standard trimming potentiometers suitable for use in these applications including multiturn through-hole models (3296 and 3006) and surface mount models (3224 and 3223). These models offer stability under extreme thermal excursion encountered by amplifiers and...

Power Resistors Power resistors are used as balance resistors and current limiters in voltage regulator/power conditioners, power amplifiers, guitar amplifiers and powered mixing consoles.
