TAPCO Reverberation Preamp/Mixer
We also offer a six-channel studio mixer and preamplification
unit that has a built-in reverberation/effects capability on
each channel. Reverberation is used to alter the quality of
dialogue recorded in a dead sound studio, making it fit the
character of the location interior. No VU meters. AC oper-
ation 110V.

Equalizers
A good equalizer is the first studio equipment investment
you should make. Equalization is almost always essential
at each transfer stage and during mixing. Equalizers can
knock out the tape hiss from less expensive sync cassette
recorders, or eliminate the low frequency wind noise dis-
tortion of a low-quality microphone. Equalizers can
increase or decrease the "presence" of a given voice, so
that during a zoom shot the voice quality will have the
same perspective as the apparent camera proximity. Equal-
izers can distort normal voice qualities to produce a wide
range of special effects we've all heard, in the Beatles' re-
cordings, for example. An equalizer is useful as a 60Hz
(and 120Hz overtone) AC hum filter, especially for trans-
fers from a magnetic edge stripe on a typical Super 8 pro-
jector.
BSR/Metrotec FEW2
The BSR/Metrotec equalizers are all hifi market devices,
which despite their low cost have excellent audio specifica-
tions comparable to or better than equalizers found in
many recording studios. Internal noise level is 80dB below
OVU, and distortion is less than .007%. The FEW2 is a two-
channel model with 5 audio bands centered at 60Hz, 240Hz,
1 000Hz, 3500Hz, and 10,000Hz. Sound can be boosted or
cut 12dB in each band. Straight line graphic controls (10).

S8S# FEW3
BSR/Metrotec FEW3
The FEW3 model is a two-channel model with 12 audio
bands in each channel (centered at 30, 50, 90, 160, 300,
500, 900, 1600, 3000, 5000, 9000, 16,000Hz). Straight
li
ne graphic controls (24). Two VU meters.

BSR/Metrotec FEW4
The FEW4 is a four-channel model with 5 audio bands in
each channel. It is essentially two FEW2's in the same en-
closure.

Compressor/ Expanders
DBX117 Compressor/Expander
A compressor allows you to fit a much wider dynamic range
of sound into the limited maximum signal/noise ratio of
most Super 8 sound equipment. With re-expansion on play-
back this is like a manually operated Dolby system. In
some respects it is superior to Dolby, since the compression
action is over the entire frequency spectrum, not just the
high frequencies as in the Dolby process. Even for release
prints that will not be re-expanded on playback, a Super 8
sound film track can be greatly improved with deft use of
the compressor on the master sound track. Two to one
compression and expansion ratios.

This version of the DBX has infinitely variable compression
and two-to-one expansion ratio.

Dolby Noise Reduction Equipment
A Dolby adapter allows any tape recorder to make Dolby-
encoded recordings, or to decode recordings made with a
Dolby unit in the field, such as the Super8 Sound XSD Re-
corder. The decoding can wait until the projection stage,
thus producing a higher fidelity sound track on the Super 8
edge stripe. Built-in calibration tone. Meter.
