Peavey PV20 USB 20-Channel Recording Mixer with USB and DSP Effects features USB Connection

Overview peavey

The PV 20 USB features built-in DSP effects with multiple reverbs and delays, plus vocal enhancer and much more, while a USB port allows direct connection to a USB-equipped computer for recording from the mixer or playing back digital audio (compatible with Mac OSX, Windows XP, ME & 2000). It also includes pre-fader monitor sends; post-fader effects send; inserts on all channels; and dual, switchable line inputs on the two stereo channels. All PV Series mixers include our Tape to Control Room and Tape to Mix assigns, which allow the operator to monitor an external stereo signal without using any of the mixer's channels. In addition, the mixers' Control Room output sends a stereo master output signal to an external source for monitoring. Phantom power, effects send and a contour switch are also standard on all models.

RITM-2 | РИТМ-2 Analog One-Voice Soviet Synthesizer [Silver Face], 1990, made in USSR


Link: ruskeys


This synthesizer was manufactured by Kirovsky musical instruments' factory in 1984, designer - Viktor Nikulin. The EMI Ritm 2 is an one-voice keyboard synthesizer designed for solo, ensembles and orchestral playing musical compositions of any genre. It can be used both for educational needs and creating different musical effects. This synthesizer can be used with an acoustic amplifier which has a response of 0,775. There is a possibility to use a low frequency amplifier such as radio receiver, TV and tape recorder. The quality of the sounding depends on an acoustic amplifier.

The synthesizer Ritm-2 can play soundings of the other classical instruments (keyboard, strings, reed and percussion instruments). It is intended for creating some specific sounds (wind, noise of surf, train, gun and whine). Using this instrument one can play some compositins with a random pitch and a timbre.
