Translstorlsed Hi-Fi Tape Link

As most owners of High Fidelity sound reproducing equipment
will know. tape recordings cannot be made from the amplifiers
and preamplifiera by simply connecting a tape deck to the
sockets marked 'Record'. A vital 'Link' between tape deck and
amplilying equipment is required. i.e. specially designed re-
cording amplifiers Incorporating high lreguency Erase/Bias
oscillators matched tor use with the heads on the tape deck.

Similarly tor playback purposes. it the very best reproduction at
all tape speeds is to be accomplished. specially designed play-
back pre-empliiiers must be incorporated between the tape
deck and the pro-amplifiers oi the High Fidelity equipment.

The New Brenell Transistorlsed l-ll-Fi Tape Llnk contains twin
recording amplifiers. Bias/Erase oscillator. twin playback pre-
amplifiers and is designed for use with a three headed stereo~
