First D&R recording desk Discrete transistor inputs Bi-FET TL070 signal path NE5534AN mix amps FET switching 90dB shutoff

The 4000 was the console that established D&R in the recording studio market — their first in-line recording desk. Discrete low-noise transistors at the mic inputs, Bi-FET TL070 op-amps in the signal path, NE5534AN mixing amplifiers, FET switching with over 90 dB shutoff, and passive filtering for above-audio frequencies. Four fully floating subgroup amplifiers, six aux sends, 48V phantom per channel. The MK2 improved on the original with refinements throughout.
