About this Product

This is a new FMR RNP - Really Nice Preamp. This is the newer version with black finish and nicer knobs!

Condition:
Brand new.

Product Details:
The Really Nice Pre-amp, the RNP, is a 1/3 rack two channel mic pre-amp that has relatively neutral sonics and is compatible with the RNC/RNLA.

The RNP is a good addition to any studio looking for an clean, full-sounding mic pre-amp.

Lots o' headroom
These days, the trend is for microphones to increase their output signal levels while reducing their output noise levels. This means either employing a front-end pad and/or increasing the headroom of a mic pre. We decided to do the latter: at unity gain, the RNP 8380 has a clip point of +27.5dBu (almost 25Volts peak-to-peak)! Even with a hefty microphone output, the RNP8380 should take what your mics have to give.

Fidelity
When designing a pre-amp, there are many ways to balance the sometimes conflicting operating constraints. Unfortunately, with the proliferation of integrated-circuit (IC) based mic pres in recent years, one of the typical casualties has been fidelity. At this point, I won't bore you with the geeky details, but I want to assure you that fidelity was not sacrificed in the RNP8380. Even though there are many mic pres that are quieter, there are very few that have the spurious-free (i.e., distortion-free) spectrum of the RNP8380. Now, more than ever, what you put into a mic pre is what you'll get out.

Really Nice Compressor (RNC) inserts
Each channel on the RNP8380 has an unbalanced send/receive jack that allow you to connect an RNC1773 using a single Tip-Ring-Sleeve (TRS) cable (per channel). With proper cabling, you could also use this feature to balance any other unbalanced piece of gear. In addition, with the right external configuration, the RNP can provide a separate +22dBu unbalanced output and a +28dBu balanced output simultaneously to allow nifty things like separate M/S decoding while tracking the M/S signal without decoding.

Balanced/unbalanced operation
Both the mic inputs and mic pre outputs are electronically balanced, differential signals. Want to run to/from unbalanced sources? No problem, the RNP automatically adjusts...no special cabling required.

Balance an RNC
Using the above features, you can allow/provide a balanced signal to/from an RNC/RNP set.

Hi-Z DI inputs
These inputs are designed to take a source, such as a passive bass, and not "suck the tone" away from the instrument. This input features a high-impedance unbalanced 1/4" jack.

Slowly-ramping 48V supply
To reduce the chance of destroying mics connected to the RNP that can't tolerate +48V applied to them, we ramp up the +48Volts slowly just in case you accidently turn on the phantom supply with a phantom-intolerant microphone attached to the RNP. In addition, this ramp helps reduce "settling time" of the RNP's servos (see Geek Stuff below) and reduces the size of the output pops/clicks.

EMI-resistant
The pre-amp's front end includes a third-order EMI filter. It is specifically designed to attenuate RF while giving a smooth audio performance up to 200kHz. This reduces the chances that you'll have trouble with RF interfering with the RNP's operation even at high-gain levels. When used with a nominal 150 Ohm balanced source, this filter yields exceptional audio performance. 

Output mutes
During phantom engagement/disengagement and DI/mic switching, we momentarily mute the output signals to reduce output pops & clicks that may otherwise annoy you and others. This mute actually occurs before the insert send signal, so even devices connected to the insert are spared large pops & clicks.

Stepped gain control
To allow precise gain-setting between multiple channels, we're using a Grayhill 12 position switch to set the RNP's gain.

Phase inversion control
This is fairly standard stuff to allow you to accommodate any phase problems due to things like system cabling, etc.

Precision metering
Three LEDs are provided for metering each channel (signal presence, +18dBu and CLIP). In addition, the clip LED trips at 1dB below actual clip and stays on for 3 seconds to make signal-chain troubleshooting easier. The metering is digitally-calibrated and driven by the internal microprocessor.

Geek stuff
An internal microprocessor provides control and monitoring of many RNP internal activities: power supply operation, source (mic/DI) selection, precision metering, push button control and phantom voltage control. The preamp itself is a unique, full Class A self-biasing-fully differential-DC servoed-transimpedance-100MHz GBP-instrumentation amp with an input impedance of 5k. The RNP's maximum level is +28dBu (differential mode) with an EIN of -120dB. High common-mode impedances help reduce the effect of interfering noise sources. Both phantom coupling caps and gain port voltages are independently servoed.
