Product overview
The VELVON V-D1 is a passive mono DI box with pure transformer isolation for high-output instruments.
No power is needed: a transformer isolates the instrument from the mixer and converts the 140 kΩ input to a 150 Ω balanced output, flat from 20 Hz to 20 kHz (±2.5 dB) with less than 0.01 % THD. A -15 dB pad, a ground lift, a 180° polarity switch and a 6.35 mm (1/4 inch) TS thru output complete it.
