Rupert Neve Designs – Portico II MBP (Master Buss Processor) – Like new!!. Condition is Used. (BEST MASTERING DEVIDE EVER, AT A PRICE YOU JUST CAN’T MISS!! ) Selling for having another one at the studio I’m working now. CompressionFor signals below the “threshold” level that has been set, a compressor provides a linear path allowing signals to be amplified without the gain being adjusted in any way. When signals exceed the “threshold” level, the gain is reduced in a controlled manner that depends on the Ratio that has been set.GainGAIN range provided is from 0dB to +20 dB. When compression has taken place, the gain control is necessary to increase the overall gain to restore the program level.LimiterMusically transparent brick-wall limiting activated when the signal reaches the limiter threshold. Attack time is .03 mS in order to reduce the first half of a 20 kHz waveform over the threshold, with Serial Adaptive Release.Bypass AllHardwire bypass for MBP, including the input and output transformersTextureContinuously variable control for Silk and Silk+ modes allows the engineer to fine tune the harmonic ratio and tonality of each channelFF/FBChanges the VCA Detection from a forward feed design (fast, more accurate attack & release) to a feed back design (smoother, more musical response)Peak / RMS Compression SelectionWhen engaged, the MBP compressor uses a combination of peak and RMS (average) detection to trigger the VCA set below 1ms. When disengaged, it follows RMS alone.SC HPFIntroduces a HPF at 125Hz to the VCA side chain signal. This allows the compressor to disregard sustained low frequency content.RatioRange from 1:1 to LIMIT (i.e. 40:1)ThresholdRange from -30dBu to +20dBUAttack TimeRange from 20 mS to 75 mS.Release / Recovery TimeRange of RELEASE time is 100 mS to 2.5 Seconds.Stereo OperationWhen the LINK switch is engaged, channel A becomes the master control, and any gain reduction happens simultaneously in both channelsLED MetersFour Peak LED METERS are provided that show stereo output levels and gain reduction.Output level meter covers the range from -10 to +22 dBu and above which is regarded as overload.The reduction is calibrated in dB covering the range 1 to 22 dBu, reading from top to bottomSide Chain Send/ReturnExternal compressor side chain send and return on 2 x TRS jacks. The send is always active and normalled to the return (NOTE: If the send and return are connected to a patchbay, the send should be normalled or connected to the return by default, as the compressor will not trigger if the return has no signal)TECH SPECSFrequency Response:Main Output, no load,–3 dB @ 4 Hz–3 dB @ 120 kHzMaximum Output Level:Maximum output from 20 Hz to 40 kHz is +24.5 dBu.Total Harmonic Distortion and Noise:@ 1kHz, +20 dBu output: Better than 0.006%@ 20Hz, +20 dBu output: Better than 0.20%As above, Silk Blue Engaged, Texture fully CW: Better than 2.5%As above, Silk Red Engaged, Texture fully CW: Better than 3.5%@ 20kHz, +20 dBu output: Better than 0.020%Slew rateBetter than 4 V/uSCompressorThreshold: Variable from -30dBu to +20dBuRatio: Variable from 1.1:1 to 40:1 (LIMIT)Blend: Variable from 0% to 100% CompressorGain: Variable from -6 dB to +20 dBAttack: Variable from 20 mS to 75 mS (0.1mS with “FAST”)Release: Variable from 100mS to 2.2 SecondsPower Consumption.65A @ 117 VAC, .35A @ 220 VACFuse5mm x 20mm, 2.5 Amp, fast acting, ceramic body – Bussman type GDA 2.5A or equivalentSize3.5”H (2U), 19”W, 12”D
