Usage Notes 

1.  Do not power on the amplifier until all input sources and speakers are securely 
connected. Turn the volume knob to its minimum setting before powering on the 
amplifier to prevent speaker damage. 

2.  The total power consumption rating of the speakers must not exce

ed the amplifier’s 

continuous power rating. The 4-16 ohm connector should not be used for 70V or 100V 
speakers. When using this connection, the total speaker impedance should be 4-16 
ohms.  

3.  If the amplifier detects a surge or irregular signal input (including power surges, 
excess signal or other interference), a short-circuit condition in the speaker wiring or an 
excessive speaker load, the amplifier will shut down for self-protection. If this occurs, 
please turn the amplifier off, check for these problems and take corrective action before 
turning the amplifier on again. 

 

Safety and Operation 

Please read before operating your unit! 

1. 

Read Instructions: This manual should be read thoroughly prior to operating the 

unit. 

2. 

Retain Instructions: This manual should be retained in a safe place for future 

reference. 

3. 

Heed Warnings: All warnings on the unit and in this manual should be adhered 

to. 

4. 

Follow Instructions: All operating and use of instructions should be followed. 

5. 

Water and Moisture: The unit should not be used near water (washtubs, sinks, in 

a wet basement or near a swimming pool, etc.). 

6. 

Ventilation: Overheating caused by improper ventilation is one of the primary 

causes of premature failure of electronics. The unit should be situated so that its 
location or position does not interfere with its proper ventilation. For example, the unit 
should never be situated on a bed, sofa, rug, or similar surface that may block 
ventilation openings; or placed in a built-in installation, such as bookcase or cabinet that 
may impede the flow of air through the ventilation openings. 

7. 

Heat: The unit should not be situated in any excessively hot area. 

8. 

Dust: The unit should not be situated in any excessively dusty area. 

9. 

Grounding or Polarization: Do not attempt to defeat the grounding and 

polarization protection provided by the design of the power adapter plug.
