The main advantages of the Parasound A21

• The international THX Ultra 2 certification guarantees correct reproduction of multi-channel DVD-Audio and SACD audio and high quality home theater surround sound, bringing it closer to the sound of a real theater;
• Adjustment of input sensitivity of each channel for optimal match with preamplifier or signal source;
• Advanced amplifier circuitry, including MOSFET and JFET transistors in the driver and input stages, respectively, as well as bipolar output transistors (15 A / 60 MHz);
• The absence of capacitors and inductors in the signal path in order to avoid its possible distortion;
• Powerful 1.2 kVA toroidal transformer with metal shielding and independent secondary windings for each channel contributes to a significant increase in power characteristics and a decrease in induced noise interference in the amplification stages;
• Relay DC protection circuitry ensures reliable and safe operation of the acoustics;
• Effective power supply stabilization using high-capacity smoothing capacitors;
• Automatic switch-on unit by 12 V trigger, as well as by incoming audio signal;
• Gold-plated speaker and RCA input connectors provide reliable contact and protection against oxidation, increasing the fidelity and fidelity of music reproduction and minimizing distortion;
• LED indication of power supply, channel status and overheating, as well as illumination of the standby mode button;
• Sleek design with a heavy duty chassis and die-cast aluminum panel with carrying handles and an included bracket for easy mounting of the amplifier in a 4U rack;
• The set of the device includes a high quality power cable and a set of banana connectors for cutting acoustic wires.
