RPN1100 / RPN1103 Mic Input, Dynamics and EQ Unit with Original VR Modules (1U)

The RPN1100 unit, also known as the Channel in a Box or CIB for short is based around the Inputs, Dynamics, EQ and Insert sub-assembly from a Neve VR channel.

The objective was to design a product that both maximised the facilities available on the Neve VR sub-assemblies and expanded upon them – all packaged in a convenient, high quality 1U rack unit.

CML Audio’s RPN1100 Neve VR Series Mic Input, Dynamics And Eq Unit is a pro-class product that has been re-engineered by professional audio engineers FOR professional audio engineers.

Enjoy the vintage Neve V Series sound in the convenience of a high-quality, compact, space-saving unit – in any studio, anywhere.

Two versions are currently available: the RPN1100 and the RPN1103 – both with the option of either a Lundahl transformer or electronic output.

Key Features

There are four distinct functional blocks within the Neve assemblies – EV11491 and EV11494 »
  • Mic / Line Input (with phase reverse).
  • High and Low filters.
  • Dynamics comprising Compressor, Limiter, Expander and Gate.
  • Four-band Equaliser with Insert.
Each are available as individual signal processing blocks or as a complete channel path with in-line capability [RPN1100 only].

In addition to the existing Neve VR facilities we have added:

1. Three LED bargraph meters:

  • Limiter / Compressor (10-segment).
  • Expander (10 segment).
  • Signal Level, switchable between Mic / Line Input and unit output (20-segment).
2. An output level control.

3. A pair of Auxiliary outputs – selectable as 2 mono or 1 stereo [RPN1100 only].

4. Phantom power cable switch [RPN1100 only].

 

Facilities

Input Stage

The mic amp design offers low noise and low distortion at all signal levels. The gains of the Mic and Line Inputs are adjusted on two continuously variable rotary controls providing a total range of -10dB to +70dB (in conjunction with -30dB PAD) for mic and -10 to +10dB for line with centre detent. Input selection is by the C/O switch. The selected mic or line input can also be phase reversed by the Ø switch.

Phantom power can be selected on/off by means of the push-on/pull-off switch on the mic gain control. This has the potential to accidentally have phantom power switched on, so a phantom enable switch has been included as a master phantom control. This has a recessed actuator and is located to the left of the C/O switch.

Patch free audio subgrouping is available via the GRP switch and this is the highest priority input, allowing a recorder output signal to be processed as a channel signal. This allows the channel to be used as an in-line audio path.

Input Filters

These are 12dB/octave high and low pass filters, with frequency ranges from 31.5Hz to 315Hz and 7.5kHz to 18kHz respectively. The filters can be switched into the channel path independently by a pull-on switch on each of the two controls.

Dynamic Control

Full limiter/compressor and gate/expander facilities are available with a fully flexible sidechain (each of which can be individually switched in or out of circuit).

The gate/expander has rotary controls for a 50dB gate range, a 70dB threshold range, release from 30ms to 3s, switchable attack time and variable hysteresis. Hysteresis makes the threshold level different for signals which are rising or falling in level and allows precise triggering on the wanted signal while still allowing the correct amount of signal decay to pass.The expander has a 2:1 expansion ratio. Switched controls are provided for an external key input and invert (for ducking). The external key input is accessed from a jack socket on the rear panel. A 10-segment LED bar graph meter shows the amount of expansion or gating.

The limiter/compressor has rotary controls for release times from 30ms to 3s with an end stop, a 50dB threshold range, a ratio of 1:1 to limiting and up to 30dB of gain make-up. Attack time is program dependent with a switch for fast impulse response. The Release control incorporates a switch for automatic programme dependent release. ‘Anti pumping and breathing’ circuitry allows the unit to operate on the source musically whilst retaining absolute control over the dynamic range. A 10-segment LED bar graph meter shows the amount of gain reduction.

Multiple RPN1100 Mic Input, Dynamics and EQ (CIB) units can be linked together for multi-channel dynamics control via the Link-Out and Link-In (phono) sockets, as well as the link switch.

The equaliser module can be inserted into the sidechain of the dynamics module for de-essing, etc.

Inserts

There are a total of four insert points and all comprise separate Send and Return jacks. The sends are always active. The return jacks form the break function. All inserts are electronically balanced at a level of +4dBu.

If any of the Pre-Filter, Pre-dyn or Post-Dyn inserts are not being used, they each have bypass switches (on the rear panel) that reduce the signal path within the unit. The Sends remain active and are always available as outputs.

The main insert point is controlled from the Equaliser and is switchable in/out as well as pre-equaliser.

Formant Spectrum Equaliser

The unique sound of Neve equalisers is the result of years of research and extensive studio experience.

The equaliser provides 4-band parametric equalisation, with overlapping frequency ranges.

The two mid-bands have variable controls for Q (from 0.5 to 9), gain (18dB cut and boost) and frequency.

The high and low frequency controls provide variable gain (18dB cut and boost) and frequency controls with switchable Q (either 0.71 to 2) and peaking/shelving characteristic.

Auxiliaries

The two auxiliary sends can be configured as two independent mono sends with either the unit input (mic or line as set by the C/O switch) or the unit output (post the output level control) as the signal source. Input is selected by the PRE switch being in; output is selected by having the PRE switch out.

The pair of sends can be switched to operate as a stereo Aux by pressing the STE switch. The two rotary controls change function so that the Aux 1 pot becomes a stereo level control and the Aux 2 pot becomes a pan control.

Each aux send has its own individual On/Off switch. In stereo mode, the Aux 1 ON switch controls both the aux outputs.

Output Level Control

The output level can be controlled between fully off and +10dB.

Level Meter

A 20-segment LED bargraph meter shows the level of the input stage (mic or line) or the output signal leaving the unit. The displayed level is chosen by the Input/Output switch. The meter ballistics can be set to be VU or quasi-peak by an internal jumper link.

Peak Indication

There are four monitoring points for the peak LED’s detection system: the Mic/Line Input, the unit output, the Post-Dyn insert send and the Equaliser output. The peak LED illuminates 4dB below clipping.

Power Supply

The internal power supply can be switched (internally) between 230V and 115V. The units are factory-set to the known country of destination, and a label on the rear-panel states what the internally set voltage is.
