4] Tips for Use
Unlike some other audio compressors that are designed to “text book” parameters, the Buzz
Audio SOC 1.1 possesses a unique “musically transparent” soft knee compression
characteristic. It is equally at home providing gentle level control of acoustic sources
through to full on squash for “in your face” lead vocals. The following operational tips will
help in getting the best out of your unit, but the final word has to be – use your ears!
• Slow Attack.
The SLOW position is useful in obtaining more fronts from percussive sounds. For example, a
snare that has no “stick” sound may be improved by gentle compression with a slow attack
and quick (1 or 2) release time. The initial transient of the snare is allowed to pass unaffected
but compression is applied to the “tail” of the sound, bringing the “stick” forward.
• Auto Attack.
Best choice for low ratio light compression of sources like acoustic guitar, bass guitar, vocals
and even stereo mixes. The adaptive nature of the auto position prevents “pumping” and
really is the “classic” sound of LDR type compressors.
• Fast Attack.
Generally, when high ratio’s and heavy compression are applied to vocals, the fast attack
position is the best choice to prevent sibilance problems. When compressing a stereo mix,
the fast position will help control peaks in the program material getting through.
• Release Times.
Selecting the most appropriate compressor release time is best achieved by ear but here
are some guidelines.
Stereo Mixes – generally a release time of 400mS (number 4 on the dial) or Auto is
appropriate, but really does depend on the type of program material.
Bass Sounds - Faster release times will distort the bass register as the compressor actually
starts to track the bass frequencies, however in saying that, the effect of a fast release may
be the sound you’re looking for!
Vocals & Voice Overs – under heavy gain reduction, 100mS release (number 1 on the
dial) will prevent “pumping” and missing phrases due to the compressor still releasing from a
loud patch. If using a low ratio and light compression, slower release or the Auto position
may sound warmer. Again, experimentation is the key.
Auto mode – a clever little circuit inside the SOC 1.1 provides a quick release from
transients and peaks whilst maintaining a slow release on overall program. This is similar to
an automatic gain control (AGC) type action, although a lot more intelligent in it’s response.
