Highly reliable logic-controlled relays

Long signal paths for functions such as input
SWitching and tape monitoring tend to degrade
high frequency response and impair imaging. In
the E- 10/E-210A, all swttching is performed by
iogic-controlled relays which are arranged so as
to permit the shortest possible signal paths. The
hermetically sealed relays are high-quality types
developed specifically for demanding communi-
cation applications. The contacts are twin cross-
bar types plated with gold for minimum contact
resistance and outstanding long-term reliability.

Versatile input configuration including bal-
anced connectors

The E-210/E-210A offers five inputs controlled by
the input selector plus another input for a tape res
corder. One input is designed for balanced cone
nections. The principle of balanced signal
transmission is shown in Figure 5. At the source
component. the signal is converted into a posnive

tial but phase‘inverted by 180 degrees. On the re-
ceiving side the two signals are fed into a positive
and negative amplifier input and combined
precisely.Since any noise which was picked up by
the connecting cable etc. has the same phase in

both lines. it is canceled by the mixing process.
ensuring noise-free signal transmission with opti-
mum sonic purity.
