SPECIFICATION

TTHRESHOLD
Controls when the compressor begins to react from -30 dB to +20 dB.  When set to +20 dB minimal to no compression is applied and and more gain reduction as the knob is rotated towards -30 dB.

RATIO
Controls the “slope” of the compression from 1.1:1 (minimal) to 40:1 (Limit).  In general, low ratio settings apply more subtle compression while high ratio settings can be more effective at preventing unwanted clipping. 

COMP IN
Illuminated push-button switch that engages the compressor.

F/F + F/B
Push-button switch that toggles between two different compressor modes, FEED FORWARD and FEED BACK. The F/B mode (button in) tends to sound smoother and more natural.  The F/F mode can be more useful for shaping the envelope of the sound and introducing more ‘pumping’, if desired.

MAKE-UP GAIN
Continuously variable control for the make-up gain of the compressor within a range of -6 dB to +20 dB.

ATTACK
Controls how quickly the compressor reacts and starts attenuating. Continuously variable within a range of 20mS to 75mS.

RELEASE
Controls how quickly the compressor stops applying gain reduction.  Continuously variable within a range of 100mS to 2.5 Seconds.

RMS/PEAK
Push-button switch that toggles between the compressor responding to the RMS level of the audio or responding to the PEAK level. RMS (root mean squared) more accurately mimics the way the ears perceive apparent loudness, while PEAK directly responds to the waveform voltage, which may be more useful to prevent clipping and maximize levels.

S/C HPF
Push-button switch that engages the high pass filter (fixed at 250Hz) for the side chain of the compressor. Please note that the high pass filter is not applied to the main audio output, this only adjusts the frequency range of the signal being compressed..

LINK
Switch that engages the stereo compressor link mode, linking the gain reduction circuits to work in tandem.

द्वार

यह नियंत्रित करता है कि कंप्रेसर कब -30 डीबी से +20 डीबी तक प्रतिक्रिया करना शुरू करता है। जब +20 डीबी पर सेट किया जाता है तो न्यूनतम या कोई संपीड़न नहीं होता है और नॉब को -30 डीबी की ओर घुमाने पर अधिक लाभ में कमी आती है।

अनुपात

संपीड़न के "ढलान" को 1.1:1 (न्यूनतम) से 40:1 (सीमा) तक नियंत्रित करता है। सामान्य तौर पर, कम अनुपात सेटिंग्स अधिक सूक्ष्म संपीड़न लागू करती हैं जबकि उच्च अनुपात सेटिंग्स अवांछित क्लिपिंग को रोकने में अधिक प्रभावी हो सकती हैं।

कंप इन

प्रबुद्ध पुश-बटन स्विच जो कंप्रेसर को जोड़ता है।

एफ/एफ + एफ/बी

पुश-बटन स्विच जो दो अलग-अलग कंप्रेसर मोड, फीड फॉरवर्ड और फीडबैक बैक के बीच टॉगल करता है। एफ/बी मोड (बटन इन) अधिक सहज और अधिक स्वाभाविक लगता है। यदि वांछित हो, तो ध्वनि के आवरण को आकार देने और अधिक 'पंपिंग' शुरू करने के लिए एफ/एफ मोड अधिक उपयोगी हो सकता है।

मेकअप लाभ

-6 डीबी से +20 डीबी की सीमा के भीतर कंप्रेसर के मेक-अप लाभ के लिए लगातार परिवर्तनशील नियंत्रण।

आक्रमण करना

यह नियंत्रित करता है कि कंप्रेसर कितनी तेजी से प्रतिक्रिया करता है और क्षीण होने लगता है।
