Details
Controls: Continuously variable gain and peak-reduction controls; GR/Output switch with VU meter; Limit/Compression switch (3:1 compression to 8:1 limiting); Normal/Pad switch (-14dB attenuation); stereo/mono link switch; bypass switch
I/O: Transformer-balanced in/out, 600-ohm
Notes: FLAGGED: unlike the rest of ADL's current lineup, the OPUS-3 is all-solid-state (not tube); ADL describes it as 'a close cousin to our world famous ADL vacuum tube 1000 and 1500,' sharing the same hand-matched optical attenuator component. Dimensions 3.5" x 7.75" x 10.5" (half-rack width, ~2U height), shipping weight 7 lb. Third-party retail listings often describe/sell it as a 'stereo pair,' consistent with its dual-mono/stereo-linkable design. Price not published by manufacturer.
