This means effectively twice the muscle of the old DC300 at the same price. Each channel has eight 150 watt devices for 1200 watts of power dissipation per channel. The DC300A is rated at 150 watts per channel continuous into 8 ohms with both channels driven, 300 w/ch into 4 ohms or 500 w/ch into 2.5 ohms. Two Amplifiers in One As a dual-channel amplifier with separate level controls and circuitry for each channel, the DC300A is almost two amplifiers in one. This gives you additional flexibility in controlling your speaker load, as when driving separate front and back speaker systems in a large auditorium, or when bi-amping a system. For 600 watts continuous output at 8 ohms, the DC300A converts to a mono amp with two plug-in parts. This makes it possible to drive a 70-volt line directly without a matching transformer. Superior Output Protection The DC300A output protection circuitry is a radically new design which completely eliminates DC fuses and mode switches and further reduces service problems to the negligible level. It is superior in every way to the old VI-limiting circuit pioneered by Crown and now used by most other high power amplifiers, since it introduces no flyback pulses, spikes or thumps into the output signal, whether operating as a single-or dual channel amp. Gone too is the need to baby the amp by carefully juggling load configurations. The Problem Solver can drive any speaker load resistive or even totally reactive with no protection spikes! Parallel speakers with no deterioration of sound quality, since changing the load impedance only affects the maximum power available, not the ability of the amp to keep on producing clean sound. Lowest Distortion and Noise Also new is the DC300A's IC front end, which sets new world's records for low distortion and noise. At the 8-ohm rated output, IM and harmonic distortion is less than 0.05% full spectrum; hum and noise is 110db below. Servicing if ever necessary is a snap, since removing the front panel accesses the entire circuitry. Although it is a completely redesigned model, the DC300A has inherited some characteristics from its predecessor: PRICE $685, the same as the 1968 introductory price, incredibly. As two amps in one, it will probably give you or your customers a welcome cost-break when you design your next multiple-amp system.
