PLATFORM

Stereo Compressor/Limiter

Congratulations on purchasing the Electro-Harmonix Platform Stereo

Compressor/Limiter. The Platform presents you with a versatile and powerful

studio-quality compressor enclosed in a stompbox-sized package. Use the

Platform’s compressor/limiter on any instrument—such as guitar, bass or

keyboards—for precise and powerful control of your signal’s volume. Engage the

Drive and Swell functions to further tailor and enhance your sound. Whether

you’re on stage, in the studio, putting together a podcast or creating your next

YouTube masterpiece, the Platform will help you get the job done.

WARNING: Your Platform comes equipped with an Electro-Harmonix 9.6DC-200BI

power supply (same as used by Boss

& Ibanez

: 9.6 Volts DC 200mA). The Platform

requires 125mA at 9VDC with a center negative plug. Use of the wrong adapter or a plug

with the wrong polarity may damage your Platform and void the warranty.

PLATFORM Stereo Compressor/Limiter Congratulations on purchasing the Electro-Harmonix Platform Stereo Compressor/Limiter. The Platform presents you with a versatile and powerful studio-quality compressor enclosed in a stompbox-sized package. Use the Platform’s compressor/limiter on any instrument—such as guitar, bass or keyboards—for precise and powerful control of your signal’s volume. Engage the Drive and Swell functions to further tailor and enhance your sound.

COMPRESSOR/LIMITER CONTROLS & INDICATORS SUSTAIN Knob Compressor Mode: Adjusts compression ratio. As you turn the SUSTAIN knob clockwise, the compression ratio increases. This ratio determines how much compression is applied to a signal once it crosses the threshold. Threshold is the volume level at which the compressor begins working on the signal. In compressor mode, the Platform’s threshold level is fixed at a constant -35dB.
PAGE 3
RELEASE Knob While the compressor/limiter is acting on the signal, the input may drop below the threshold setting and cause the compressor to cease working on the signal. The compressor does not stop working immediately, though. Rather, it gradually stops over a period of time that is set by the RELEASE knob. As you turn this knob clockwise, release time increases, or slows. Slower release settings generally result in smoother, more transparent compression with little or no audible artifacts.

LIMITER Button Press the LIMITER button to engage the limiter. The button lights green to indicate that the limiter is active. A limiter is a compressor that is fixed at an extremely high—practically infinite—ratio. As a result, the signal level does not increase past the threshold setting. The ATTACK knob can still be used to delay the limiter’s attack. The states of the KNEE and LIMITER buttons (as well as the DRIVE footswitch) are saved in flash memory and restored each time the Platform is powered up.
PAGE 5
SWELL CONTROL The Swell algorithm is triggered every time a new note is played. The normal attack of your instrument is replaced by a sound that fades in slowly. The Swell function is located after the overdrive and compressor functions in the signal chain, but before the main VOL knob. Swell has just one control, the SWELL knob. Swell mode works best on instruments that have a quick attack and long sustain, such as a guitar, bass, synthesizer or organ. SWELL Knob Adjust fade-in time with this knob.

MONO/STEREO OPERATION MONO IN & OUT: Left In -> Left Out: when using the Platform in mono, connect to the Left Input and Left Output. MONO IN, STEREO OUT: Left In -> Left Out & Right Out: same connections as mono in and out but add the Right Output. The Right output signal will be identical to the Left Output both in effect and bypass modes.
