S R M - 8 0 A / E – S I G N A L R O U T E R / M O N I TO R
The SRM-80A provides a high-resolution 40
LED x 2 bar graph meter to display the signal
selected for listening. The meter displays a
pre-fader signal for accurate monitoring of
the signal going to tape or disc. This meter
has true VU ballistics, or can be switched to
Peak Program Mode via the front panel toggle
switch. The meter also features a slow re-
lease-time Peak Hold function to allow easy
ver i fi ca tion of critical levels.
The SRM-80A’s MONO SUM feature provides
the ability to check for radio compatibility,
and is a good spot check to see how you’ve
messed up the stereo image! (Only the sends
to the speakers are af fect ed.) While radio air-
play is nearly always stereo these days, phas-
ing problems and odd panning ar range ments
can show up in less than ideal listening envi-
ronments, such as cars, and many lo ca tions in
nightclubs.
The SRM-80A also features a DIM switch to
allow an easy way to lower the level to the
speakers (but not the headphones) tem po -
rari ly without disturbing any level controls.
