The Sony APM-66ES (mk2) is an audio power amplifier designed for professional applications in cinema, broadcast, and live sound. It is a successor to the APM-66ES (mk1), the main upgrades being improved noise performance, expanded equalization functions, and higher current drive capability. Some key features of the APM-66ES (mk2) include:1. Maximum output power of 650 watts into 6 Ω (stereo) or 1300 watts into 4 Ω (bridge) per channel, in a compact 2RU layout. This provides plenty of headroom for driving long cable runs, as well as ensuring low distortion and high fidelity reproduction.2. Extensive equalization functions, including up to 15 dB of bass management, 10 dB of high-pass filtering, and 15 dB wide-range and 10 dB narrow-range parametric EQ per channel. These options allow for precise tailoring of audio to specific acoustic environments and speaker configurations.3. Improved noise performance, achieved through the use of high-quality components, such as a double-sided printed circuit board, select components for the AC filter, and reduced capacitance and wiring length for the audio circuitry. This results in a THD+N rating of less than 0.1% at full output, even at low frequencies.4. Enhanced reliability, including the use of electrolytic capacitor banks for stressful power supply conditions, and the implementation of a modular chassis design that enables easy maintenance and replacement of faulty components.5. Flexible input/output connectivity, including balanced XLR and unbalanced TRS jacks, as well as support for AES/EBU, S/PDIF, and analog signals.6. Low-noise voltage regulator (LDO) power supply, which provides stable and clean power to the amplifier's sensitive circuits, reducing noise and distortion.Overall, the Sony APM-66ES (mk2) is a high-performance and versatile audio power amplifier that delivers excellent audio quality and reliable operation in a variety of professional audio applications. Its advanced features and improved noise performance make it a popular choice for cinema, broadcast, and live sound engineers and technicians.
