K30 AMPLIFIER BENCH RESULTS
Line Voltage During Test
250 volts, 60 Hz
Metering Used
Amprobe Clamp Meter
Clarke-Hess Power Analyser
Hewlett Packard Distortion Analyzer
Klein Tools Clamp Meter
Amplifier Temperature During Tests
Starting Temperature: 39 Celsius (102.2 F)
Ending Temperature: 45 Celsius (113.0 F)*
Room Temperature: 17.7 Celsius (63.86 F)
Note: Room Temperature was measured with a Klein Tools Dual Laser Infrared Thermometer
* Excluding Longevity Test
Amplifier Thermal Status (From The Manual)
Normal: 32 – 69.0 Celsius
Overheat Warning: 69.1 – 75.0 Celsius
Thermal Protection: 75.1 Celsius
Burst Ratings (Keele Tone-Burst Test) 50 Hz, 63 Hz & 80 Hz
https://www.prosoundtraining.com/2015/1 ... urst-test/
Frequencies: 50 Hz, 63 Hz, 80 Hz
Wattage: 9227.52, 9467.29, 9467.29
Load: 4 ohms
Note: Each Output Channel, under a 4-ohm load, registered anywhere from 48.03 – 48.65 amps in rush current (10 pulses per frequency) undergoing the Keele Tone-Burst test. The amplifier completed the test with no issues. The burst were made using the left channel of the audio files. They are available free to download (Link Above) in which, you can get an idea of the type of pulses the amplifier had to endure during the test.
Line Source Current Consumption Under Burst Ratings Using A 4-Ohm Load
250-volt Line Source: 37.86 amperes (Single Channel) Measured
240-volt Line Source: 39.45 amperes (Single Channel) Estimate
240-volt Line Source: 78.9 amperes (Both Channels Driven) Estimate
120-volt Line Source: 78.9 amperes (Single Channel) Estimate
120-volt Line Source: 157.8 amperes (Both Channels Driven) Estimate
Continuous Sinusoidal Wave
Frequency: 59.89 Hz
Wattage: 3398.89
Load: 4 ohms
THD: 1.0%
Note: The amplifier can offer this kind of wattage continuously with no significant drops in output power and, no ramping into protect mode. The clip lights (Yellow Indicators) are not on @ 1.0% THD. The amplifier does reduce it's wattage slightly once the clip lights are present. The output power is reduced to 3317.76 watts. The Clip Limiter may be the culprit as, it is factory default in an ON position. Once the Clip Limiter is turned off, the slight drop in wattage is not present. Please bear in mind, moving from 3398.89 watts to 3317.76 watts only yields a -0.10 dB loss.
Dynamic Headroom 4-ohm Load
From 3398.89 watts to 9467.29* watts: +4.45 dB *
* Highest Measured Peak Wattage rating based on an in-rush current of 48.65 amps using a 4-ohm resistive load.
Crest Factor
Frequency: 59.89 Hz
Wattage: 4806.03*
Load: 4 ohms
* Manufactures advertised specifications is 5000 watts per channel @ 4 ohms. 5000 watts vs 4806 watts offers a mere -0.17 dB loss
Crest Factor 100 Hz – 5 Hz
100 Hz: 4806.03 watts @ 4 ohms
90 Hz: 4806.03 watts @ 4 ohms
80 Hz: 4806.03 watts @ 4 ohms
70 Hz: 4806.03 watts @ 4 ohms
60 Hz: 4806.03 watts @ 4 ohms
50 Hz: 4806.03 watts @ 4 ohms
40 Hz: 4806.03 watts @ 4 ohms
30 Hz: 4806.03 watts @ 4 ohms
20 Hz: 4806.03 watts @ 4 ohms
10 Hz: 2809.08 watts @ 4 ohms
5 Hz: 1328.34 watts @ 4 ohms
LONGEVITY TEST
Starting Temperature: 45 Celsius
Ending Temperature: 55 Celsius
Frequency: 40.04 Hz
Type: Sinusoidal Wave
Duration: 2:52.049 (Two Minutes, Fifty-two Seconds)
Load: 4 ohms
Starting Voltage: 104.4 volts (2724.84 watts)
Ending Voltage: 104.4 volts (2724.84 watts)
Amperage From 4-ohm Load: 26.10 A
Amperage From 250-volt Line Source: 10.89 A
The amplifier maintained a constant output voltage from start to finish. The only noticeable difference from the amplifier was an increase in Celsius and, Fan Speed. The amplifier was -0.96 dB away from clipping (1.0% THD) playing a 40 Hz sinusoidal wave continuously for nearly three minutes.
Note: Test was halted due to the 4-ohm resistor. The 4-ohm resistor began delivering a heavy dose of smoke. The objective of this test was to determine how long the amplifier would maintain it's output voltage under a 4 ohm load before ramping into protection or reducing it's output (Whichever came first). Since the resistor began to give off heavy smoke, the risk of an electrical fire was too high. The test was halted and further measurements were put off to a later date. The amplifier's thermal rating (55 Celsius) once the test was halted, is still within it's normal thermal status. The K30's overheating warning begins at 69.1 Celsius.
Audible Difference In dB Output
3398.89 watts @ 4 ohms versus 2724.84 watts @ 4 ohms: 0.96 dB differential
