Countryman Type 10 Direct Box
Direct box design normally forces a trade: chase ultra-low distortion and the input noise climbs, insist on true ground isolation and you pay in phase deviation or level. The Type 10 answers that with an analog circuit that tunes itself to the signal: 10 Hz to 50 kHz within 1 dB, THD under 0.001% at 1 kHz, and phase deviation of 0 degrees from 100 Hz to 20 kHz, all measured through 200 ft of XLR cable into a 1.2 kOhm load.
It drives a board across hundreds of feet either on 48 V phantom or on a 9 V battery good for about 130 hours, with transformer isolation rated at 500 V from instrument ground to XLR pin 1. Three pad settings take hot keyboard outputs up to 190 Vpp, and the input survives 220 V line voltage and 20,000 V static.
