1.AVplay A-75 Class A HiFi amplifier (80-300W)*2 load in the state of 8/4/2 ohms, bridged 280 ~ 80W load in the state of 8/4/2 ohms, the designer in the learning and absorption of the Golden Voice A series of excellent Class A amplifier circuit on the basis of the ability to output more power, with a new chassis heatsink design, the sound characteristics: the sound of warmth and a sense of grain, good phase, accurate positioning, the singer as if in front of you. The sound features: warm sound with a sense of grain, good phase, accurate positioning, the singer as if in front of you, the sound field is full of dynamic range wide, large dynamic put and take freely, low-frequency corresponding to the speed of fast bounce good.

2 .The A-75 has 40 high-power field effect transistors together with a large number of ELNA/ENA, NICHICON/Nichicon capacitors in the elaborate circuitry. The materials and components in the circuits are better than the original amplifier; Schotly rectifier,20 Sprague and Philips large capacitors ( actual tests have found that Sprague capacitors produce better listening experience), and multi-capacitor arrays have more advantages than ‘large ponds’ capacitors design. Multiple capacitors connected in parallel will greatly reduce the internal

resistance, and charge and discharge faster during dynamics transitioning.

3. The A-75 has 2 X 1000W ring transformer, providing ample power reserve. Power Reserve: 2 x 1000W toroidal transformers, providing a powerful enough power reserve. Bridge state limit power up to 800W (2 ohms).

4. The A-75 has bridging function, the bridge power is 4 times greater, the greater the power, the deeper the bass. In bridged mode 2 X power amplifier will easily handle any speakers on the market even the highest impedance speakers.

5. The A-75 has substantial heatsink each side weighing 4.5Kg. The heat sinks is aesthetically design and yet thermally functional to radiate heat away from the core of the amplifier. The radiation effect of the heatsink induces efficient air convection than other conventionally design heat sinks, drawing more heat from the inner gut of the amplifier; achieving effective cooling to maximise the performance of the amplifier.

6. The A-75 VU meter is adjustable, the thickness of the rhythmic bar can be adjusted in 2 levels, and the brightness can be adjusted in 4 levels.

The amplifier has a large visually appealing display which indicates the operating temperature of the Class A amplification during operation. The aesthetically large designed display also presents the rhythmic beats of the music and the status of the amplifier better than traditional VU meter, and is viewable from a distance of 3-5 meters.
