LA-40MKIII
Line converter (balanced/unbalanced, bi-directional)
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 RC A 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.
