maintain cone control. It?s kind of like grabbing a swing
at the bottom of it?s travel and trying to push it the other
way - it could knock you over. If the amplifier doesn?t
have this ability, the sound is unresponsive and less out
front. The amp loses it?s punch and feel at higher
playing levels. Instead of responding to your every
command, the amplifier simply cuts those transients off,
leaving you with the feeling that something is missing
in your sound.
Since most amplifiers have limited output current
capacity, they need ?current limiting circuits? to
protect against self-destruction. High-power tran-
sients trigger these circuits, which rob the amplifier of
it?s ability to control speaker cones. This creates a
mushy, unresponsive feel to your sound. The 700RB
Series has extremely high current capacity, so it
doesn?t need current limiting circuits for over-load
protection. |
