For those, like myself, who didn't know what an "Alpha-Delta VRC" was I
post a url to some reviews. It is a Variable Response Console (VRC) or
sophisticated speaker -- with controls! :-)

Not all reviews are favorable, but several are very favorable.

The price is about 1/2 of MSRP.

Here is what Bob Grove has to say about it near the bottom of url:

Alpha Delta VRC Speaker

Review by Bob Grove

In the past few years, several manufacturers have released digital
signal processing (DSP) audio accessories for customizing sound under
noisy shortwave (and scanner) reception conditions. Some have automatic
heterodyne notching and background noise reduction, some are cumbersome
to operate, some add noise artifacts, and most (if not all) lack
"warmth" in their sound as a result of the digital shaping of the audio.

Alpha Delta's VRC (Variable Response Console) is an attractive,
easy-to-operate package with an internal speaker. Its sturdy, diecast
enclosure is visually pleasing, and the LED bargraph brilliantly
announces the low pass filter cutoff settings from 400 to 10,000 Hz. A
second LED bargraph shows bass boost/attenuation by up to 12 dB. An
operational folder is included, containing equalization graphs of the
various control settings.

The notch/peak filter is continuously adjustable from broad (for voice
and music) to razor sharp (to peak or reject narrow-bandwidth data or
single-tone interference). Resultant audio is quite listenable, although
harsher than produced by an analog processor.

A 1/4-inch front-panel jack invites the use of headphones when speaker
operation is undesirable. A rear panel tape output (RCA phono jack) is
provided. The VRC is powered by 12 VDC (AC adaptor provided). A shielded
patch cord with 1/8-inch plugs and a 1/8 to 1/4-inch adaptor plug are
included.

Although functions are limited to simple audio contouring (which it does
very well), the Alpha Delta VRC is one of the easiest to use and
acoustically acceptable DSP** audio processors we have tested. And it
has a decent internal speaker, not universally found in competitive
DSP** products.

The VRC speaker accessory is available for $249.95 from Alpha Delta,
Inc., Highway 25 North, East Bernstadt, KY 40729; call (606) 843-6567.

**ED NOTE: Although the VRC speaker does use digital filtering, it is
NOT a digital signal processor. The reviewer misinterpreted some wording
in Alpha Delta's publicity to mean it was. The speaker's pleasing
performance, however, speaks for itself.
