Descrizione
Two channels in one box is a compromise engineers make for cost. A monoblock is what happens when nobody is trying to save a chassis.
The argument for one amplifier per speaker is not exotic. Each channel gets its own power supply, its own ground path and its own thermal budget, so nothing that happens at the left speaker can affect the right one. Stereo separation, noise floor and transient behaviour all improve, and no amount of cleverness inside a shared chassis replicates it. What has held the idea back is price and size: monoblocks were traditionally large, hot and expensive. The V3 Mono is none of those. It is a 240 watt desktop monoblock, and the design deliberately scales, so you buy one for a centre channel, two for a pair of bookshelf speakers, or five for a surround system built from identical parts.
The amplifier uses the TPA3255 class D chip with PFFB post filter feedback, which corrects the load dependent behaviour that class D designs normally show in the top octave. Component selection is specific rather than generic: Japanese NICHICON and ELNA capacitors, German WIMA capacitors and Sumida inductors from Japan, all inside a metal chassis. The measurements back the approach, with a SINAD of up to 93 dB through the RCA input and 101 dB through the balanced input, a signal to noise ratio reaching 123 dB, and a noise floor of 31 microvolts. Inputs cover both RCA and balanced XLR or 6.35 mm TRS, and the RCA path offers two gain settings, 19 dB or 25 dB, selectable from the front panel.
Buy the V3 Mono when you want to build a system by adding identical blocks rather than replacing a whole amplifier. One unit drives a centre or a passive subwoofer channel, two form a stereo pair with genuine channel isolation, and adding a third, fourth or fifth extends the same architecture into a home theatre without a change of character. The 48 volt supply options cover the power budget, with a 5 amp unit for a single amplifier and 10 amp options with filtering or fan cooling for multi-channel builds. Choose the bundle that matches your speaker sensitivity, and add units later as the system grows.
One amplifier per speaker is not excess. It is the shortest path between the source and the driver.

Application Scenarios
The V3 Mono suits the listener who is building a system in stages rather than buying it whole. A pair drives bookshelf speakers on a desk or in a small room with channel isolation that a stereo chassis cannot match. A single unit powers a centre channel or a passive subwoofer in a home theatre, where the 240 watt output and 31 microvolt noise floor keep dialogue clean. Installers use identical blocks across a five channel system because matching parts make level and character consistent without measuring each amplifier. Because each unit takes standard analogue inputs, the same design works with a desktop DAC, a preamp or an AV processor.
Frequently Asked Questions
Q: How many units do I need for stereo?
Two. Each V3 Mono drives one speaker, which is the point of the design: separate power supplies and separate ground paths for left and right.
Q: Can I add channels later?
Yes. The architecture scales from one channel to two, 2.1, three, four or five channel systems by adding identical units.
Q: Do I need the 10 amp power supply?
A 48 volt 5 amp supply suits a single amplifier or a stereo pair used at moderate levels. The 10 amp options include power filtering or fan cooling and are intended for multi-channel builds running hard.
Q: What is PFFB and why does it matter?
Post filter feedback corrects the load dependent frequency response that class D amplifiers typically show near the top of the audio band, keeping the output linear into real speakers.
Q: Does it accept a balanced source?
Yes. The balanced input accepts XLR and 6.35 mm TRS connectors, with SINAD measuring up to 101 dB on that path.
Q: Is it suitable for a subwoofer?
A single unit drives a passive subwoofer channel at up to 240 watts, though for high excursion designs check the impedance and power requirement of your driver.
