QBASS PLUS™
QBASS PLUS™
On POWERCLASS™ amplifiers, we've taken bass control to a higher level with QBASS PLUS™ . The two QBASS switches (labeled 1 and 2) on the front end of the amplifier allow you to select one of four frequency centers - 30 Hz, 36 Hz, 44 Hz and 60 Hz. The Q SELECT switch determines the width of boosted frequencies. A 'Q' of 2 (switch out) will give you a wide boost while a 'Q' of 4 will boost a narrow range of frequencies (See chart below). On the rear end panel you will find the QBASS level control and the
