Do not remove the cover to avoid high voltage hazard. Please refer servicing to qualified personnel.

Do not explore the unit to rain or moisture.

Do not block the ventilation of the unit to ensure cooling efficiency.

Check whether the local voltage is identical with the operating voltage of the unit.

Please disconnect the unit from the power supply when it is not to be used for a long time.

Do not let the equipment run for a long time with overload.

2.PERFORMANCE FEATURES

Symbol Definition

The equilateral triangle containing a arrowheaded lightning symbol is intended to alert the user of the presence of uninsulated ''angerous voltage'' within the equipment's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons.

The equilateral triangle containing a exclamation mark is intended to alert the user to the presence of important operating and maintenance instructions in the literature accompanying the appliance.

Series E products are high-performance big-power professional amplifiers which suit various applications for sound reinforcement. The following shows the main features of Series E models.

1. High power output, big driving capacity.

2. Adoption of optimized heatsink structure and high quality cooling fans ensures system reliability and allows the unit to run long hours with high power output.

3. Series E features interactive control over temperature of loaded impedance, power and working voltage. Speed of the cooling fans can change automatically according to inner temperature. When the loaded impedance is too low or the inner temperature is too high, the equipment will adjust the power supply voltage and reduce the power supply impedance, which helps to protect the system, and improve sound quality and reliability efficiently.

4. Low distortion

5. High slew rate helps to boost definition and achieve better sound

6. Low noise with the S/N ratio>108dB(A)

7. Frequency response: 20Hz-20KHz <+0/-0.25dB

8. 2U-rack compact design

9. E800 is specially designed for driving low impedance load, capable of driving 2 load for a long time.
