1. Channel 1 Input Attenuator.
Use to attenuate the input signal of channel 1. Pressing the control for 2 seconds mutes Channel 1.
2. Channel 1 volume scale indicator.
This indicator displays the volume attenuation of Channel 1.
3. Channel 1 clip LED.
Illuminates at the clipping threshold, Continuous illumination also indicates that ACL (Active Clip
Limiting) protection circuitry is engaged.
4. Channel 1/2 Limit LEDs.
Indicate that the ACL (Active Clip Limiting) protection circuitry is limiting the input signal to protect the
speakers from damage caused by a clipping amplifier.
5. Channel 1/2 TEMP LEDs.
These LEDs will light if the temperature of CH1 or CH2 exceeds 95
o
C.
6. Channel 2 clip LED.
Illuminates at the clipping threshold, Continuous illumination also indicates that ACL (Active Clip
Limiting) protection circuitry is engaged,
7. Channel 2 volume scale indicator.
This indicator displays the volume attenuation of Channel 2.
8. Channel 2 Input Attenuator.
Use to attenuate the input signal of channel 2. Pressing the control for 2 seconds mutes Channel 2.
9. Power LED.
Indicates that AC power is connected and the amplifier is turned on.
10. Air entrance.
TAS Series amplifiers are cooled by two, rear-mounted fans, Cool air flows over the heat sinks and
exhausts through the rear grills, Make sure these outlets remain clear to allow unrestricted air flow.
11. Channel 1 Mute LED.
If channel 1 is muted, the LED will light.
12. Channel 1 output level indicator.
Indication range: -22dB to +6dB.
13. Channel 1/2 VHF LEDs.
Indicates that channel 1 or 2 are in VHF protection mode.
14. Channel 1/2 ON LEDs.
Indicate that channel 1 or 2 are active.
15. Channel 1/2 DC LEDs.
Indicate that channel 1 or 2 are in protection mode.
16. Channel 2 output level indicator.
Indication range: -22dB to +6dB.
17. Channel 1 Mute LED.
If channel 2 is muted, the LED will light.
18. AC Power Switch.
This is the main Power switch. Press to turn the amplifier on.
Illuminates at the clipping threshold, Continuous illumination also indicates that ACL (Active Clip
Limiting) protection circuitry is engaged,
