11. 12-BAND GRAPHIC EQUALIZER.
This is a dedicated bass instrument equalizer designed to give you precise tone control of
your instrument. It is a very powerful tone processor, which with a little understanding
will give you the greatest benefit in getting the most out of your instrument and sound
system.
12. PARAMETRIC EQ ON/OFF SWITCH.
You can switch in or bypass the parametric equalizer circuit with this.
13. PARAMETRIC EQ-ON INDICATOR.
This will light up blue when you are going through the parametric EQ.
14. VARIABLE FREQUENCY 30-200Hz PARAMETRIC.
Select frequency from 30 to 200Hz.
15. LEVEL CONTROL 30-200Hz PARAMETRIC.
Adjusts level +/- 15dB of selected frequency.
16. VARIABLE FREQUENCY 300Hz-2KHz PARAMETRIC.
Select frequency from 300Hz to 2KHz.
17. LEVEL CONTROL 300Hz-2KHz PARAMETRIC.
Adjusts level +/- 15dB of selected frequency.
18. VARIABLE FREQUENCY 3KHz-15KHz PARAMETRIC.
Select frequency from 3KHz to 15KHz.
19. LEVEL CONTROL 3KHz-15KHz PARAMETRIC.
Adjusts level +/- 15dB of selected frequency.
A Note on the Parametric EQ.
Some instrument amplifiers have a pre-set EQ, which may have a selected feature of
bypassing it or modifying it to another factory-selected pre-set.
The PJB parametric is designed to give the player the exact amount of pre EQ required
without the confines of a pre-set. It is infinitely adjustable so your tone can be
exclusively yours.
The best method of setting the parametric is to have the Graphic EQ switched off. Once
the ideal tone is close, fine adjustment can then be done on the graphic EQ. This
combination will give an infinite number of tonal possibilities.
Again care should be used in boosting of low frequencies. The M-500 although
compact is a very powerful amplifier that is capable of sending large amount of low
frequency power to your speakers.
20. MASTER VOLUME CONTROL.
This is the master volume control and it controls how much power you send to your
speakers. When setting up your tone or plugging in your instrument, you should keep this
control at a low level to avoid damaging your hearing or your speakers.
