ASCOLTA is dual high fidelity input preamp with envelope follower and peak detector output for each channel. a
• 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
• 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–
Ascolta consist of two individual high quality preamp
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
S: the first input will accept stereo 3.5mm standard cables from any source and split L and R to output I1 O1
and O2 respectively. 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.
• Two high quality 40dB amplifiers.
• Customizable internal normalization.
• Audio graded potentiometers.
• “Whatever” power connector a.k.a. don’t mind the polarity.
• dimensions width 4HP, depth mm 25
• current draw +12V 50ma, -12V 30ma.

That’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.
Nerd 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.
