The equalizer is definitely the most important piece of equipment in your audio rack! Most transceivers do an excellent
job of passing all the midrange frequencies between 300Hz ~ usually with an added dominance between 500Hz ~ 800Hz. Unfortunately, most
stock transmitters roll-off the bass frequencies below about 150Hz and down, as well as the high frequencies above about and up. So, we
need to do basically three things:
* Reduce the Midrange
* Increase the Bass
* Increase the Treble
Taking a look once again at GRAPH 1 and GRAPH 2 above, you can see what an EQ can accomplish when set up. Below is a graphical representation of what EQing I had to implement in order to get some flatness out of my Kenwood TS-850S/DSP-100 after passing through its . and DSP filtering.
Effects are often incorporated into amplifiers and even some types of instruments. Electric guitar amplifiers typically have built-in reverb and distortion , while acoustic guitar and keyboard amplifiers tend to only have built-in reverb. Some acoustic instrument amplifiers have reverb, chorus, compression and equalization (bass and treble) effects. Vintage guitar amps (and their 2010-era reissued models) typically have tremolo and vibrato effects, and sometimes reverb. The Fender Bandmaster Reverb amp, for example, had built-in reverb and vibrato. Built-in effects may offer the user less control than standalone pedals or rackmounted units. For example, on some lower- to mid-priced bass amplifiers , the only control on the audio compression effect is a button or switch to turn it on or off, or a single knob. In contrast, a pedal or rackmounted unit would typically provide ratio, threshold and attack knobs and sometimes "soft knee" or other options to allow the user to control the compression.
