The ASR Emitter II Exclusive B w/gold board is a premium integrated amplifier featuring a dual-mono design housed in an acrylic enclosure with large aluminum-alloy heatsinks. It delivers 280W per channel into 8 ohms, 490W into 4 ohms, and 900W into 2 ohms, powered by four 700VA transformers and a high-capacity power supply with 957,520 uF buffering capacitors. The amplifier includes a battery-powered input stage that eliminates the need for an intervening linestage, providing exceptionally pure and dynamic sound. It offers multiple inputs including balanced XLR and unbalanced RCA with gold-plated laboratory-grade solid brass sockets and Teflon insulation, solid silver wiring for signal paths, and a relay attenuator volume control with 1dB steps. The unit is equipped with extensive protection circuits and features a high signal-to-noise ratio (>86 dB), ultra-low distortion (<0.001%), and a frequency response from 1 Hz to 100 kHz (+/-1 dB). The amplifier is accompanied by two external power supplies and an optional battery power supply for the input stage, ensuring stable and clean power delivery. The design emphasizes minimizing electromagnetic interference by separating power supplies and using high-quality materials throughout. The amplifier weighs approximately 111 kg without the battery supply and includes a high-quality Corian remote control. The gold board variant includes gold-plated components and massive brass feet for enhanced resonance control and aesthetic refinement.
