vrs23 time





ac
REVERB MODE a simulated reverb as the circuit using delay lines from analog BBD chips.



button

UPPER: when switched to REVERB mode some parameters can be changed using the delay commands:
- time buttons are the reverb intensity
- regeneration is the duration
- delay knob is the density.




ac
DELAY MODE up to 400 ms of delay time in delay mode with a stereo ping pong effect.
There are 4 echo modes: 50 / 100 / 200 / 400 ms


regen2

Some delay parameters can be adjusted:
- delay: sets the delay time
- regeneration: sets the number of echoes.
TIP: - shortest time create typical flanging and chorused effects.





ac FILTER
the TONE control is simple analog lowpass filter.

LFo





LFO
single triangle-shaped oscillator modulates the amplitude



LFo

the LFO two sub-controls:
- SWEEP FREQ is the frequency rate
- DEPTH is the modulation amount.




acREVISION MODELS
also in white face version:

ac there are at least 2 revisions models with different chipsets:

tda1097P
Upper: first version (black one?) with N823-OM then white one with TDA 1097 8-pins variation of classic TDA 1022 + 10 BBD bucked brigade devices.

REVIEW" Warmy sound and not too muffled. Today a a bit overvalued / overrated in vintage market, but it is for sure an interesting machine."

manual manual
- retro sound - pricey
- intuitive
-scarsing BBD chips

"Welcome to VRS23, previous reverb generators all suffer from the same shortcoming - at short echo and reverb durations the sounds is hollow and metacclic, like a cellar or in the bathroom" manual (uh bathroom?)
