New "80s-Style" YouTube audio demo:

(PM me for google drive link to uncompressed 24-bit WAV files of this demo)

New features for 2024/2025:

-New aluminum Advanced Damper System for superior sound and durability.

-Fully-enclosed internal plate frame for improved noise isolation and RF protection.

-Upgraded internal Stereo Driver System (SDS) with easy access to drivers for service/modding.

-Vastly improved stepper motor remote control system.

-Front panel ground lift DIP switches for pesky XLR ground loop hum situations.

-Re-designed to withstand the roughest shipping with zero damage to the plate.

-Fast and easy damper lockdown for effortless moving/shipping; simply set decay time to about midway (3s) and you are ready to go!

All-Tube Amplifiers:

The internal all-tube amp is essentially an improved/modernized clone of the legendary 1950's V54S tube amps found in the very first production plate reverbs of the late 1950s. All class-A/single-ended on both pickup and drive amps; results in super thick and warm sound with lots of pleasing harmonic distortion and the ability to push the amp into some amazing tube distortion!

The CVPlate-RST adds expanded EQ options on the front panel to include: 4-position stepped driver LPF, HPF (as per the original), pickup HPF, and on-board jumpers to disable the built-in mid-cut and high-boost pickup EQ's (if you'd prefer to use your own outboard EQ instead).

It uses modern-production equivalents to the tubes used in the original since some of them are rather expensive and/or starting to get more rare. For authenticity, all tube-types are the same as the original, i.e. the EF804S pentode is now EF806S/EF86 pentode, E80CC dual-triode is now the 12BH7/ECC99 dual triode (pin-compatible with original tube), and the E81L power pentode is now the EL84/EL844 power pentode. There are TONS of possible tube combinations and additional substitutes that tube-nerds might want to try out!

Advanced Stepper Remote System:

This vastly improved system uses Japanese-made Sanyo/SANMOTION stepper motor and near-silent German Trinamic TMC2209 stepper driver for super-quiet and reliable remote control of damper/decay time. Includes RRCU 1RU rackmount remote control unit. Common RJ45 Cat5/6 cables for connecting remotes (NOTE: not network/ethernet compatible). Open-source stepper control software available to customers (upon request) for modification (literally every line of code has a detailed comment) or to add your own self-developed experimental features like MIDI or CV control: if you know C++, the possibilities are endless! The new expansion socket on the internal remote control board allows users access to nearly every single pin on the CPU + all voltages, sensor output, and remote control decay time +/- switch outputs. Expansion socket pinout/layout available to all customers upon request.

CTPS PSU:
The beefy power supply features low-noise fully-regulated DC on all outputs, to include the filament. The noise is so low, its actually on-par with the super quiet solid state version! This is one of the safest power supplies around, with thermal overload protection and 4 x fuses. Standard 2mm multimeter test points make this a service techs dream come true!

A wide selection of plate material available to include:

Brass (free) - 0.7s - 4.5s @ 500hz - Longest high freq. decay time - Medium resonance

Nickel (+$800USD) - 0.7s - 4s @ 500hz - Medium high freq. decay time - Medium-low resonance

Cold Rolled Steel (free) - 0.7s - 4s @ 500hz - Medium high freq. decay time - High resonance

Options:

-Nickel plate (+$800USD)

-Jensen (USA) input transformers x 2 - optional +$190USD (50% Ni; includes mu-metal shield)

very cool might be getting one of these someday

Would you need to have a seperate room to keep it away from loud monitors in the control room (because of spill) ?
I love the sound of Plate reverb.
I'd imagine that this would sound unreal !

The CVPlate-RST has a remote control to avoid this issue entirely - it will work with nearly unlimited lengths of Cat5/6 cable: you could put the plate just about anywhere and cabling costs for the remote would be very low (you'd still need a 4-channel XLR snake though).

I would recommend placing the plate in the quietest room or closet you have - unless you don't mind working with headphones in the control room. I personally use headphones since I have limited space and time with each unit to record audio tests - I record all my tests/demos in my small workshop.

Since this new design is more isolated (the plate is now fully enclosed inside the unit like an EMT 240), you might be able to use it in the control room at low monitoring volumes and subwoofer turned off - maybe hiding the plate behind a couch or something with some low-freq. absorption. Even then, I'd recommend using headphones for the final reverb take so there is zero bleed (even if you are blasting your headphones right next to the unit - like I do, there's not enough low freq. to cause any issues).

The big issue with using a plate in the control room is low frequency feedback: the wavelengths are simply too long for a small enclosure to block. If you need to run a subwoofer while monitoring, it would make feedback sensitivity even worse.

Hello from CVPA!

Here's the new Nickel vs Brass audio demo video for the PlateMic-S!
https://www.youtube.com/watch?v=Et4wfex2cdg

This is a Blues/Rock inspired demo recorded with Nickel and Brass PlateMic-S units side-by-side for an accurate comparison of both plates. All tracks recorded direct-to-plate through the front Adjustable Sound Ports (ASP) for a full and rich sound. Feel free to ask questions about the recording!

Serious buyers, please contact me on Reverb or PM for Google Drive link to all the Nickel vs Brass 24-bit WAV files (includes all tracks from the YouTube video, Stems (with no effects), and the entire Reaper project folder.
