AUDIOPHONICS TRIPATH TA2022 Mini-Kit DIY + Transformer

This new version uses more surface components, and a revised power supply (simple diode bridge for ground loops).

The input stage now accepts RCA and XLR signals with an AOP 5532.

Based on the architecture Class-T of the famous brand TRIPATH, this AUDIOPHONICS amplification module is characterized by a high quality reproduction for a very compact product.

The chip TA2022 integrated, it is possible to achieve 2 x 90 Watts under 4Ω with a level of harmonic distortion extremely well controlled since not exceeding 0,1%.
A power that does not sacrifice in any way the precision of this circuit prodigy renowned connoisseurs for these musical virtues.

To protect your speakers, this card has a protection circuitagainst the possible presence of a continuous component.
A timer also avoids unpleasant noise when switched on.

Jumpers are used to select the balanced (XLR) and unbalanced (RCA) inputs.

This version is now bridgeable to reach 150W under 4ohm.

Warning, this amplifier may be sensitive to radio interference from FM radios and tuners./ P>
