The RDL DB-SH1M is a compact dual-channel mini headphone amplifier designed to drive headphones of any impedance from consumer or professional audio sources. Ideal for language translation, museums, interview studios, and music stores, the DB-SH1M provides high-quality audio in a small, convenient form factor.
This module accepts balanced or unbalanced left and right inputs with operating levels from -20 dBV to +20 dBu. Two recessed side switches allow pre-mounting selection of input sensitivity and mono/stereo operation, with the left input driving both channels in mono mode.
A long-life VCA stereo level control on the front panel ensures noise-free adjustment without passing audio through the potentiometer. The amplifier delivers over 50 mW into high or low impedance headphones via a mini-jack output. Designed to operate from a 24 Vdc power supply (PS-24AS recommended), the DB-SH1M combines performance, reliability, and compact installation flexibility.
