The RDL TX-1A is used primarily for galvanic isolation and format conversion between equipment. Conversion from -10 dBV consumer level up to +4 dBu professional level requires voltage gain. The transformer in the TX-1A has a 1:1 ratio and uses an adjustable attenuator circuit at its output to lower the output signal to the level required. The module cannot provide voltage gain.
RDL offers several premium quality conversion amplifiers to produce professional signals from consumer sources. RDL also offers a passive transformer based converter, the TX-AFC1M. This module provides level and format conversion from+4 dBu professional level to -10 dBV in exceptional quality.
