Frequently Asked Questions
Q: What is the continuous rated output power of the Electro-Voice 7300A amplifier?
A: We offer a variety of output power ratings, the dual amplifier mode giving an output of 800 watts with an 8 ohm speaker load and in bridge mode the load is 600 watts with an output of 8 ohms.
Q: How does the high power of the cooling system of the 7300A function?
A: This high speed fan draws about 50 CFM during low speed and 100 during high speed making the dual fan load temperature dependent.
Q: What is the input sensitivity that is expected for rated output power?
A: The input sensitivity for the rated output power of both dual mode running at 4 ohm and for bridge mode running at 8 ohm is determined to be set at +0.1 dBu (0.78V rms).
Q: In any ventilation considerations, what are the possible precautions?
A: To avoid overheating of the device, the amplifier in use must remain properly ventilated and must not be installed in locations where the outside temperature is above 60 °C or 140 °F.
Q: Is it true that the 7300A amplifier is capable of operating in both dual and bridge modes?
A: Yes, the 7300A can function independent channels or combine its channels to make one with greater power output.
Q: The “PROTECT” LED has turned on, what action should be taken?
A: The illumination of the “PROTECT” LED indicates that the amplifier has already begun its power limitation due to excessive amount of current being supplied. To cut electrical length, use protective measures since continuous use might result in a shutdown.
Q: This amplifier has a maximum allowable input level?
A: The input allowed maximum level which this amplifier can accept is +20 dBu..
Q: How much does the Electro-Voice 7300A amplifier weigh and what is its height and width?
A: The dimensions are 5.25 inches high, 19 inches wide, and 18 inches deep. It weighs 42 lbs when transported while its naked weight is 34 lbs.
