Compressor

Threshold This 31-detent potentiometer adjusts the level at which the compressor begins to attenuate the signal and is fully vari- able within a signal level range of +20dBu to -30 dBu. If the compressor input signal level exceeds the set threshold level, compression will occur.

Ratio This 31-detent potentiometer adjusts the compressor slope between 1:1 to 40:1. Example: if the ratio control is set to 3:1, and the signal level exceeds the set threshold by 15dB, the compressor will attenuate the signal level by 10 dB from input to output, allowing the output to increase in level by a total of 5 dB.

Blend This 31-detent potentiometer adjusts the mix ratio of uncompressed (dry) signal with the compressed (wet) signal. When Blend is fully counter-clockwise (CCW), only the uncompressed signal is audible. When Blend is fully clockwise (CW), only the compressed signal is audible. Setting Blend anywhere between 0% and 100% achieves parallel compres- sion.

Comp In This illuminated push-button switch engages the compressor-limiter section on its respective channel. Engaging or disengaging the “Comp In” button never affects SILK status and will not affect SFE status unless SFE to COMP is engaged.

Bypass All This illuminated push-button switch toggles the PIIMB’s hard-wire bypass on both channels. When engaged, the PIIMB’s Neutrik XLR input jacks are directly connected to its Neutrik XLR output jacks, eliminating all internal amplifier circuitry from the monitor path, thereby accomplishing a true bypass. This can be used for A-B comparison at any time. In the event that the PIIMB experiences a loss of AC power, the PIIMB will automatically switch to hard-wire bypass mode.

FF/FB This illuminated push-button switch toggles between two different compression modes: Feed Forward and Feed Back. The distinction between these two types of compression is that the side-chain detector of a feed-forward compressor is fed from the compressor input, before the gain control element, while the side-chain detector of a feed-back compressor is fed from the compressor output, after the gain control element. Vintage compressors were more commonly feedback designs, whereas a lot of modern designs tend to utilize feedforward topologies.

Ultimately, each topology has its own advantages and disadvantages, so we encourage the user to experiment with both modes, then choose the most suitable mode for their particular application. In very general terms, feedback com- pression tends to sound more natural, but can’t achieve some of the dynamic envelope control that is available with feedforward compression.

Note: Due to the nature of the side-chain manipulation between these two compression modes, Feed Back mode reduc- es the overall compression ratio range indicated on the PIIMB’s front panel silkscreen. The silkscreened ratios are only available in Feed Forward (default) operation.

4 MBP Front-Panel Features

Gain This 31-detent potentiometer provides two different functions. When used with the compressor, the Gain control acts as standard Make-Up Gain, allowing the user to add gain to the compressed signal to match the bypassed signal level.

When used in the context of the PIIMB limiter, the Gain control allows the user to set the desired “ceiling” of their mix (in dBu) with the “Limit” potentiometer. Once the Limit potentiometer is set to the desired maximum level, the user can increase the Gain until the average mix level hits the desired loudness. The Gain control will drive the level of the mix up to the set Limiter threshold, but will not exceed it.

When evaluating the quality of compression, it is vital to match the compressed signal level to the bypassed signal level. A deviation of less than one decibel can trick the human brain into thinking that something sounds better or worse. Utilize the “Comp In” or “Bypass All” push-button switches to match the uncompressed and compressed signal levels. Once the levels are matched, a valid A-B comparison of the compression settings can be performed accurately.

Attack This 31-detent potentiometer sets how quickly the compressor will attenuate to the input signal once it exceeds the set threshold. When set to its fastest setting (20 ms), the compressor can attenuate the leading edge of a transient, like the initial strike of a drum stick on a snare drum. By compressing the inital strike, the overall compression result will increase the emphasis of the snare’s decay or resonance. When set to slower attack settings, the compressor will ignore most of the initial transient and attenuate the drum’s decay instead, thereby increasing the emphasis of the drum stick hitting the snare drum.

Release This 31-detent potentiometer adjusts how fast the compressor will return to unity gain after the signal level crosses below the threshold. Generally, slower release times will minimize compression artifacts, especially when combined with slower attack times. Faster release times can be utilized to maximize apparent loudness. It is important to exercise caution with fast release times, fast attack times, and high ratios, since combinations of these three can cause intermod- ulation distortion, resulting in undesired compression artifacts.

S/C 125 Hz This illuminated push-button switch engages a 125Hz 12dB/octave Sallen Key High Pass Filter into the compressor-lim- iter side-chain. Removing low frequency information from the compressor-limiter side-chain detector can help to mini- mize compressor pumping and over-compression of the rhythmic dynamic information that tends to reside in the lower frequency range: kick drums, bass guitar, etc. This usually results in a smoother compression characteristic.

RMS / PEAK This illuminated push-button switch modifies the compressor side-chain detection. The default detection response is RMS (Root Mean Square) averaged, which better mimics the way our ears perceive loudness. PEAK mode detection responds more directly to the incoming compressor audio signal, which can be used to prevent clipping and maximize overall loudness.

Link The link control sums the side-chain information from both compressor-limiter channels, enabling Channel A’s controls as MASTER. While linked, both channels are directly controlled by Channel A’s controls, including: Comp In, Attack, Release, RMS/Peak, Threshold, Ratio, FF/FB, Gain, Blend, Silk Mode, Silk Texture, Limiter Threshold, Sidechain Insert, and Sidechain HPF. 5 MBP Front-Panel Features Limiter Limit This 31-detent potentiometer controls the threshold of the soft-clip limiter section. The limiter is disengaged until the user rotates the Limit potentiometer past the 3rd detent (+24dBu) from the fully clock-wise (OFF) position. As the user rotates the threshold control counter clock-wise, the limiter’s release time gradually increases. This creates a smoother dynamic response as the amount of limiting increases. The limiter side-chain features a compound timing network that allows the limiter to respond equally well to quick transient material as it does to less dynamic program material. The PIIMB limiter can be utilized as a maximizer by setting the Limit potentiometer to the desired maximum level in dBu, then increasing the amount of Gain until the desired program loudness is achieved.

Stereo Field Editor (SFE)

Within the stereo field, there is information that is centered within the stereo field that is phase coherent; such as kick drum, snare, and bass guitar. There is also information that resides on the left and right sides of the stereo field that is not phase coherent, such as the natural reverb and ambience in a room, effects processing and instruments recorded in stereo. Utilizing sum and difference techniques, it is possible to isolate, then emphasize or de-emphasize the “Mid” and “Side” information. The PIIMB’s Stereo Field Editor provides an enhanced version of a Mid-Side encoder for the user, with an added EQ section for targeting specific frequency ranges of the Mid-Side processing.

Depth In This illuminated push-button switch engages the Stereo Field Editor “Depth” pot and allows for A-B comparison.

Depth This 31-detent potentiometer adjusts the overall level of the center (mid) information within the SFE’s M-S encoding. The MIN (fully CCW) position will de-emphasize the center information within the stereo image, whereas the MAX (fully CW) position will emphasize the center information. If the Depth control is at the 12 o’clock “0” position, no Depth pro- cessing will be audible.

Width In This illuminated push-button switch engages the Stereo Field Editor “Width” pot and allows for A-B comparison.

Width This 31-detent potentiometer adjusts the overall level of the side information within the SFE’s M-S encoding. The MIN (fully CCW) position will de-emphasize the side information within the stereo image, wheras the MAX (fully CW) posi- tion will emphasize the side information. If the Width control is at the 12 o’clock “0” position, no Width processing will be audible.

Depth EQ This illuminated push-button switch engages the 4-position rotary switch that allows the user to select between four different EQ settings for Depth processing: Low Frequency (LF), Low Mid (LM), High Mid (HM), and High Frequency (HF).

Width EQ This illuminated push-button switch engages the 4-position rotary switch that allows the user to select between four different EQ settings for Width processing: Low Frequency (LF), Low Mid (LM), High Mid (HM), and High Frequency (HF).

SFE to Comp This illuminated push-button switch routes the Depth and Width information to Channel A and Channel B compres- sor paths, respectively, allowing the user to manipulate the dynamic content of the Mid and Side information. When engaged, the width and depth controls allow the user to blend the amount of compressed Mid and Side information that is mixed back into the audio path. While SFE to Comp is engaged, the stereo compressor is only available for SFE dynamic processing and is not operational within the main audio path. 6 MBP Front-Panel Features (continued)

Silk This illuminated push-button switch toggles through the available SILK transformer harmonic saturation modes: OFF, RED, and BLUE. Red Silk has a high frequency emphasis associated with the transformer harmonics, while Blue Silk has a low frequency emphasis associated with the transformer harmonics. We encourage the user to experiment with both modes to find the most suitable tonal coloration for their particular application.

Texture This 31-detent potentiometer allows the user to adjust the amount of Silk transformer saturation added to the signal path when Silk Red or Blue modes are engaged.

Gain Reduction Meter This 16 segment LED bar-graph meter indicates compressor-limiter gain reduction, indicated in dB. After 4 dB of atten- uation, the LEDs turn to amber and after 8 dB, the LEDs turn red.

Output Meter This 16-segment LED bar-graph meter indicates output level, indicated in dBu. The top-most red LED is calibrated to illuminate at +25dBu, corresponding to the maximum output level of the PIIMB.

MBP Rear-Panel Features
