Mark 6 Stereo Unit

The pleasures obtained lrom Hi-Fi sound rer
producing systems can be greatly enhanced
by the addition ot really top quality tape re-
cording eqmpment-but we must emphasise
that the tape machine must be a quality item
it it is to do justice to the Hi-Fi installation
and give satisfactory results

Brenell. who have a worldwide reputation tor
manutacturing high quality tape recorders,
have designed a new Tape Unit especrally
tor the HiFi enthusiast and contidently otter
this unit as a worthy addition to any Hi-Fi inr
stallation

Apart from the clean. modern styling. a great
deal ol attention has been devoted to the im-
portant parameters ol signal to noise ratio.
frequency response. wow and tlutter. cross-
talk and erasure levels to produce a QUALITV
unit. A/B switching is incorporated to enable
an immediate comparison between the re-
corded and the original sound. Mixing tacili-
ties enable comments to be included in the
recording.

A three-motor deck mechanism, the system
demanded by protcseional recording on
gineers. gives quiet tape transport at very
constant speeds. The electronics - two
recording and two tape replay pre-amps. are
lully silicon transistorised and compensated
tor tour tape speeds.

Large-scale illuminated meters clearly indicate
the recording level. The unit may be used in
the horizontal or vertical positions or mounted
in your Hl-Fi system

The pleasures obtained from Hi-Fi sound reproducing systems can be greatly multiplied byi'the
addition of really top quality tape recording equipment-but we must emphasise that the tape machine
must be a quality item if it is to do justice to the HirFi installation and give satisfactory results

Brenell, who have a worldwide reputation for manufacturing high quality tape recorders, have
destgned a new Tape Unit especially for the Hi-Fi enthusiast and confidently offer this unit as a worthy
addition to any Hi-Fi installation

Apart from the clean, modern styling, a great deal of attention has been devoted to the important
parameters of signal to noise ratio, frequency response, wow and flutter, cross-talk and erasure levels
to produce a QUALITY unit A/B switching is incorporated to enable an immediate comparison between
the recorded and original sound to be made Mixing facilities enable comments to be included
in the recording

A threemotor deck mechanism, the system demanded by professional recording engineers, gives
quret tape transport at very constant speeds The electronics-two recording and two tape replay
ore-amps, are fully silicon transistorised and compensated for four tape speeds

Large-scale illuminated meters clearly Indicate the recording level. The unit may be used in the
horizontal or vertical positions.
