K-Series Balanced Current Amplifier™
K1 - Full Power into 8 Ohms
Sensitivity Power at 8 ohms Gain
1.4 V (+5.21 dBu) 350 W 31.55 dB
2.65 V (+10.7 dBu) 350 W 26 dB
K2 - Full Power into 8 Ohms
Sensitivity Power at 8 ohms Gain
1.4 V (+5.21 dBu) 475 W 32.88 dB
3.09 V (+12 dBu) 475 W 26 dB
Note: Bold type indicates selectable option on amplifier.
Note: 0 dB on the mixer = +4 dBu
1) Verify that the mixer is operating at its correct output
level. See if there is a +4/-10 dB switch on the output; if
so, set it to the +4 dB position.
2) Turn the amplifier level controls all the way down
(counter-clockwise). Then, move the sensitivity switch to
the 1.4-V position. This will increase the gain of the am-
plifier; 5.5 dB for the K1 and 7 dB for the K2. Now care-
fully turn the amplifier level controls up (clockwise) to
the desired level (loudness). Take care when you are
adjusting the level controls at this input sensitivity set-
ting. Increasing the input sensitivity of the amplifier may
cause the input stage of the amp to overload, so be pre-
pared to back down the output of the mixer by 1 or 2 dB
if you notice the amplifier’s clip indicators beginning to
flash.
