- 90 Watts RMS ' Mike Mixing
- Dolby FM - Convenience Controls

The Powerhouse LR-9090 AM/FM/Stereo FM and
Dolby FM receiver has the most up»to-the-minute fea-
tures: dual tuning meters, a stereo program indicator
and positive phase-lock-Ioop circuitry and multiplex fil-
tering. The FM Dolby noise reduction system enables
you to get the most from the new Dolby broadcasts.
The Powerhouse LR-9090 has the most power weve
ever offered. And weve added features youve never
had on any receiver. The LR-9090 has a mike mixing
feature that turns the 9090 into a mixing studio. Com-
bine live mike input with other sources to get balanced
recordings. The dual tape monitors have Lafayettes
tape dubbing feature.

The input section of the advanced LR-9090 provides
two phone and two tape inputs for the kind of versatility
that means this receiver is ahead of its time.

The convenience controls enable you to get the most
from your system. The tone defeat switch lets you hear
the sound direct from the source, but when you want to
tailor the sound use the separate detent controls for
volume, balance and base, treble plus midrange. Bass
and treble controls have dual range turnovers. There
are dual range filters for high and low frequencies. Con-
venience controls also include audio mute, loudness
switches and push/connect terminals for up to 3 pairs of
speakers.

The LR-9090 combines power, features and control to
make it the working heart of your stereo system. The
LR-9090 can take you as far into music as you want to

go.
