Tascam LA-40 MkII
Line Amplifier (RCA/XLR bi-directional)
|
 |
The Tascam LA-40 MKII 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 dBm/-20 dBm,
balanced) which enable the user to connect for instance four
tracks of a multitrack recorders (ins and outs) to a balanced mixer ensuring
optimum
level and impedance matching.
Switches on the bottom panel allow to select
a nominal level of +4 dBm or -20 dBm for each channel and ±6 dB trim
pots on the front panel make perfect level matching easy. The LA-40 MKII
has
also ground lift switches for each channel and a combined
master switch to avoid ground loops.
