GRAPHIC EQUALIZER
The Smartman offers a 7-band graphic equalizer. This
helps enhance your audio output sent both through the
Speaker ("Amp") and stereo output connectors ("Main").
This GEQ works independent of that featured on the Digital
Effect Processor. Both can be utilized simultaneously or
you can choose to use one or the other.
Each of the GEQ's 7 bands allow 12 dB of cut or boost
to the available frequency bands. These bands are 63Hz,
150Hz, 350Hz, 1KHz, 2KHz, 6KHz and 12KHz. This gives
sufficient control of low, mid and high frequencies, however
fine control can be achieved by using the 31-band graphic
equalizer found in the Digital Effect Processor.
Your GEQ settings should be based on an analysis of
your room acoustics. The 708A can be utilized to better
read room acoustics, although many professionals play it
by ear. To use the 708A for this purpose, play pink noise
through the speakers and use the RTA function to read
the room's response. After saving a few readings, the
708A's equalizer calculator can be utilized to give you the
suggested curve of your graphic equalizer.
