QBASS PLUS™
QBASS PLUS™
On the PC1800 amplifier, 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 30Hz, 36Hz, 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
