ADL 600

ADL 600

Designed with famed tube-circuit guru Anthony DeMaria, the ADL 600 employs a Class A, discrete design with three vacuum tubes per channel and ±300V power rails for maximum headroom and superb tone. The 2U rack-mount preamp uses only the finest components, including custom-designed transformers; there are no op-amps or ICs in the signal path. The result is a world-class, ultra-low-noise preamp with a big, warm, smooth, clear, distinctive sound.

Features include 2 input channels, each with: Mic, line, and instrument inputs

• High-voltage, Class A, dual-transformer, vacuum-tube preamp

• Variable mic-input impedance (150, 300, 900, 1,500)

• Variable high-pass filter (40, 80, 120 Hz)

• 8-position Gain switch

• Backlit VU meter (output level)
