Now I need a rack full of them!вЂќ Johnny Sandlin I really like it on vocals, sounds good on acoustic and electric guitars as well. Even at more severe compression the sound is the same, very smooth and natural. It helps control the level of the source without changing the sound. вЂњThe JM 115C is one of the very best compressors IвЂ™ve ever used. It does not pad the input (reduce level) before compression, allowing maximum dynamic range from your mic pres ect.ДЄvailable in either the 500 Series module or the stand alone that will run off the same supply as the JM-130 mic pre. The JM-115C has a very short and direct signal path allowing for very low distortion and very low noise, itвЂ™s a very clean transparent compressor. Like the 160VU the JM-115C is very easy to set up, simply start at a low ratio, set the threshold around +4 to +10dB and output where needed to get the level to tape you need.! Compression ratio starts at a very low 1.25:1, for a very small amount of compression, preventing clipping the recorder input but not over compressing. The JM-115C is a Transformer coupled In/Out VCA based compressor using true RMS detecting similar to the DBX 160VU. Note: 20 to 20 kHz filter used -10dB 38 Hz & 32 KHz, -20dB 90 KHzДЇar wider than the typical Brick wall filter, which is -20dB Compressor.Laser Engraved lettering, letters will not wear off.Phantom switching: voltage ramps up to reduce popping with condenser mics.Pad: 8dB on output, enabling the output transformer to be driven harder.> 105dB 20 to 20KHz filter w/150 ohm load max gain.Dynamic Range: >128dB 20 to 20KHz filter w/150 ohm load min gain.-127dB W/20 to 20KHz Filter W/300 ohm load Gain.Noise: -128.5dB w/ 20 to 20kHz filter w/150 ohm load Gain Max Gain: -3dB 990 Op Amp Only: +-1dB 5Hz to 500Khz.Frequency response: +- 1dB 10hz to 170khz +-.25dB 10 to 50Khz.007% Input 990 Op Amp Slew Rate: 18Vus 150 Ohm Load Output Transformer Option: Nickel or Steel.Very high headroom & Wide Dynamic Range.The Phantom switch: the phantom voltage ramps up to reduce the pop when powering a Condenser mic. Third being on the output allows the output transformer to be driven harder for a warmer sound.ДЄll switches on both the JM-130 & JM-530 are the large Gold plated switch, to provide very long life and improve the clarity of the signal path, and greatly reduce the probability of noise and static. The Pad is on the output: this has several advantages One it does not affect the loading and sound on the mic, Two Since No DC voltage goes thru the switch (Phantom) like most Mic pre pad circuits on other mic pres there is NO pop when the switch is engaged. Very high Input headroom: for a very wide Dynamic range, ov er 131dB for the JM-130, >128dB for the JM-530. JMK AudioВ are now using the SonicImageryLabs 990Enh Op Amp.
