Tube vs. solid-state technology. It's a debate as old as transistors. Now you can have the best of both worlds with the DCL-200 Compressor/Limiter from a leader in high-end gear, Summit Audio. Based on a proprietary hybrid design, the DCL-200 two-channel compressor-limiter combines the most desirable sonic characteristics of vacuum tubes with the increased reliability of solid-state devices. Its circuitry incorporates selected 12AX7A vacuum tubes with high-reliability 990 op-amps in a transformerless signal path. This exceptional compressor is perfectly suited for use in professional recording studios, MIDI project studios, broadcast facilities, sound reinforcement, and mastering studios. Features include: Continuously variable attack and release times, variable slope, soft-knee transition characteristics, sidechain inserts, and peak overload indicators.
