The Tascam LA-40 MKIII has been primarily designed to provide matching capabilities between professional equipment and semi-professional or consumer equipment. It consists of four RCA inputs and outputs (–10 dBV, unbalanced) as well as four XLR inputs and outputs (+4 dBu/–20 dBu, balanced) which enable the user to connect for instance four tracks of a multitrack recorder (ins and outs) to a balanced mixer ensuring optimum level and impedance matching. Also, a switch matrix allows channels to be linked, utilizing the converter as a distribution amplifier for splitting signals to multiple recorders, or for multizone sound routing applications.

Switches on the bottom panel allow to select a nominal level of +4 dBu or –20 dBu for each channel and ±12 dB trim pots on the front panel make perfect level matching easy. LEDs on the front panel indicate signal presence for each channel. The LA-40 MKIII has also ground lift switches for each channel and a combined master switch to avoid ground loops.
Main Features
