K Series Power Amplifiers
Operation Manual
4.2 Front Panel Controls and
Indicators 
Figure 4.1 below points out the controls, indi-
cators and connectors on the front panel of the 
K Series amplifiers. The K1 and K2 look identi-
cal except for product nameplates and fuse 
specifications.
A. Level Controls
The Level controls, one per channel, adjust the 
input attenuation from 0 dB to 100 dB.
B. Indicators
Figure 4.2 shows a close-up view of the indica-
tor LEDs (4 per channel).
TLC: The TLC (thermal level control) indicators 
turn on with a dim glow a little before the 
amplifier needs help dissipating heat. This 
forewarning gives you a chance to turn on a fan 
or other auxiliary cooling (if available), or turn 
down the level controls of the amplifier. If you 
do neither, the amplifier will automatically 
begin to protect itself with its TLC protection 
system by subtly and dynamically reducing the 
gain as needed. The TLC indicators gradually 
turn brighter as the TLC protection becomes 
greater.
Clip: Turns on when distortion becomes audi-
ble in the amplifier output.
IOC: The yellow Input /Output Comparator 
indicators turn on when distortion reaches 
0.05%, which is well before the distortion is 
audible.
Signal: The green Signal indicators flash 
dimly when a very low-level signal (as low as 
10 mW) is present in the output. They flash 
brightly when a louder signal (at least 1 watt) is 
present at the output.
C. Enable Indicator
The green Enable indicator turns on when the 
amplifier has been turned on and has power.  
When first turned on, there will be a
2-second delay while the amplifier performs a 
quick start-up test. Then the Enable indicator 
will turn on to its full brightness. If no signal is 
present, the Enable indicator will switch to a 
dimmer green.
D.Power Switch
Amplifier is on when the top half of the switch 
is depressed.
