ASCOLTA
dual preampfollower
ASCOLTA is dual high fidelity input preamp with envelope follower and peak detector output for each channel. a
why
•To amplify stereo line level signals up to modular levels 100x (40dB). –
•To extract an envelope and a peak detector CV from any given signal.
•To integrate into your system two separate sources requiring dedicated gain compensation.
•To side-chain and compress using the two audio-follow CV out and an external VCA/LPG. er
with
•Laptop / phone – plug a stereo cable directly from their output and integrate that to your modular.
•Dynamic microphones – amplify two of them individually and sing with a friend.
•External synths take those weak signals and warm them up to modular levels. –
•Passive instruments sing and play the guitar while affecting them with your spaghetti monster–1.
how
Ascolta consist of two individual high quality preamp2 connected to an envelope follower and a peak detector output.
On the back of the module you can select the behaviour of its internal normalization when no cable is plugged into
I2:
S: the first input will accept stereo 3.5mm standard cables from any source and split L and R to output I1 O1
and O2respectively. This way you can directly amplify stereo signals without the need of external splitters
and regulate the gain of each channel individually.
G: the second amplifier will double the amplification of the first totalling a gain range of 80dB - 10.000x.
Envelope and peak E P outputs are strictly related to the gain level of their corresponding amplifier and will follow
the dynamic of any input plugged.
features
•Two high quality 40dB amplifiers.

•“Whatever” power connector a.k.a. don’t mind the polarity.
specs
•dimensions width 4HP, depth mm 25
•current draw +12V 50ma, -12V 30ma.

1That’s actually how Ascolta came to be. I was in need of a small module capable of amplifying two sources simultaneously while being able to extract their dynamics to control the rest of the system.
2Nerd stuff here: in the gain stage Ascolta uses two Texas Instruments LM4562 in a two pole inverting amplifier configuration. More info and detail about the chip can be found on its datasheet.
