Power output: 130 watts per channel into 8Ω (stereo). service manual - kimz. Verstärker: 6,4 kg 10.2. #1 Best Seller. Downloads. Specifications. Total harmonic distortion: 0.006%. The amplifier is not rated for loads other than 8 ohms, but its measured output at clipping into 4- and 2-ohm loads was 118 and 56 watts per channel, respectively. There was a slight interaction between cartridge inductance and phono response at frequencies above 7,000 Hz, depending on the specific cartridge used. The remaining front-panel control is a knob-operated speaker switch controlling two pairs of speaker outputs. Even in normal operation the top of the amplifier becomes rather warm, and proper ventilation is important. Low-Pass Filter. One would also expect Sigma Drive to correct for any frequency-response changes caused by the impedance of the speaker cables. Weight: 27kg. The amplifier was stable with capacitive loads as great as 3 microfarads across the resistive loads. On the other hand, we cannot imagine a cleaner-sounding amplifier, not one which can come closer to equaling its test-bench performance when driving real loudspeaker systems. The program-selector buttons offer a choice of tape a. tape b, aux, tuner, and phono inputs. If you have additional documentation please consider donating a copy to our free archive. Song is Move by The Mims. Though it says it only has 150 x 2 rms it actually has closer to 450 rms bridged at 4 ohms.

Another front-panel switch converts the phono preamplifier from a moving-magnet (MM) cartridge input to a high-gain, 100-ohm moving-coil (MC) cartridge input. The output stages use a "zero-switching" bias system to minimize crossover distortion. Total harmonic distortion: 0.003%. Part of Kenwood's penultimate high-end set, along the L-1000C preamp, L-1000T tuner and L-1000D CD player - unfortunately all quite bland looking and sloppily designed. Though hardly likely to be audible under any conditions, this distortion level can no longer be summarily dismissed since it is not far below the levels attained by some good speaker systems at the frequency and power levels we used. Variable High-Pass Filter. The 1-hour preconditioning period at one-third rated power made the top of the KA-1000 uncomfortably hot over the heat sinks, but elsewhere it was quite cool. I would reccomend this amp along with the sony xplod subwoofer to anyone looking into a sub and amp set that wont break the bank ($190 total). The Sigma Drive eliminated the high-frequency roll off, actually converting it to a slight increase in output. Only the speaker a outputs include the Sigma Drive terminals, and a red light above the speaker switch indicates when it is in use. The slew rate was about 100 volts per microsecond, quite close to the rated 120 volts per microsecond, and the IHF slew factor exceeded our measurement limit of 25. Shop By Price. Power output: 55 watts per channel into 8Ω (stereo) Frequency response: 20Hz to 50kHz. With a purely resistive impedance, these effects would merely follow the impedance characteristic of the speaker; with series inductance they would also show up as a loss of high-frequency output. Planet Audio AC1000.2 2 Channel Car Amplifier - 1000 Watts, Full Range, Class A/B, 2-4 Ohm Stable, Mosfet Power Supply, Bridgeable. All the preceding measurements were made using the Sigma Drive circuit and with the test loads connected to the amplifier via its special four-wire cables. However, we wish that the KA-1000's controls had been more versatile and effective and the control labeling more visible. At lower power outputs the distortion was still lower. Die Zutaten können selbst gewählt werden, was besonders in Hinsicht auf die Zuckerzufuhr, Farb- und Konservierungsstoffe ein deutlicher Vorteil ist. In addition to Sigma Drive, the Kenwood KA-1000 has wide-band circuitry with full d.c. coupling from the preamplifier's high-level inputs to the speaker outputs (a low-frequency filter can be switched in to provide d.c. isolation as well as some attenuation of turntable rumble). Kenwood KM-X1000: User Guide. The usage between the two Amp were 50/50.

The third-order IM distortion at 18,000 Hz was -83 dB and the second-order distortion at 1,000 Hz was -84 dB, both referred to 100 watts output. Turning on the Sigma Drive reduced the total variation to about 0.5 dB. We measured its IHF intermodulation distortion using equal-amplitude signals, at 19,000 and 20,000 Hz, whose combined peak value was equivalent to that of a sine-wave signal at 100 watts output. The phono input overloaded at 270 to 290 millivolts depending on frequency (referred to equivalent 1,000-Hz values). To exaggerate the effect of long connecting cables, we also made measurements with an extra impedance in series with the speaker line at the amplifier where it would allow the Sigma Drive to operate with full effectiveness. Portable Kilowatt SSB or CW QSK Amp. Farbe: Silber 7. In fact, it’s one of the better tuners ever made by anyone. (4) Kenwood KFC-1695PS 320W 6.5” 3-Way Speaker + Gravity WZ1000.4 1000W 4 Channels 2/4 Ohm Stable w/Remote Sub Control Amplifier + Amp Kit With the 400-Hz and 3-kHz turnover settings, the tone controls caused considerable change of overall gain; halfway settings of the controls produced a gain change of 2 to 3 dB, with little alteration of frequency response. At the rated 100-watts output, the distortion was under 0.001 per cent from 20 to 1.000 Hz, and it rose linearly at higher frequencies to the rated 0.005 per cent at 8.000 Hz and 0.01 per cent at 20,000 Hz. From the front, the Kenwood KA-1000 presents a distinctive appearance, with the lower portion of its panel covered by a smoked-glass panel behind which can be seen a number of bar-knob and pushbutton controls. Manual Library / Kenwood. The Sigma Drive converted this to a nearly flat response, varying only ±2 dB over the full range. The result, as Kenwood puts it, is to "effectively place the amplifier across the speaker terminals." Diffrent song. Gewicht: 10.1. Its effect would also be quite dependent on the particular speakers used. In addition, the position of the volume slider gives an indication of how loud the sound can be expected to be when the signal is fully restored. Even if the full benefits of Sigma Drive probably can be realized only under rather special conditions, and even though it produced no spectacular results in our installation, we consider it to be a genuine step in the right direction and, unlike some other circuit developments of recent years, not at all in the "gimmick" category. D Series Amplifiers provide a powerful solution in a compact design, ideal for upgrading your car audio system. Dimensions: 440 x 166 x 446mm. Kenwood L-1000M. The top-of-the-line integrated amplifier in the Kenwood "Purist" Series is the KA-1000, rated at 100 watts per channel into 8-ohm loads from 20 to 20,000 Hz with no more than 0.005 per cent total harmonic distortion. When we inserted the 4-ohm resistance in the speaker line (with Sigma Drive off) the second-harmonic distortion rose to -47 dB (0.45 per cent). Holiday Gift Guide 2020. The best simulation is a real speaker, so we connected the amplifier to a high-quality three-way system (the KEF 105.2) and measured the response and distortion at the speaker terminals. COVID-19. The controls are not detented, but the bypass switch makes it easy to return to a flat-response condition whenever one desires. Phono 1, 2 MM: 2.5mV, 3… KAC-5001PS. If only the speaker a terminals are used, it is easy to check the audible effects of Sigma Drive by switching to A + B, which disables that circuit. Input sensitivity: 2.5mV (mic), 2.5mV (MM), 150mV (line) Signal to noise ratio: 65dB (mic), 65dB (MM), 75dB (line) Output: 150mV (line), 50mV (DIN), 1V (Pre out) Speaker load impedance: 4Ω to 16Ω. Sigma Drive makes the extremely low distortion of the amplifier more readily available to the speaker. Hergestellt in: Japan 6. User manuals, Kenwood Amplifier Operating guides and Service manuals. View and Download Kenwood KM-X1000 instruction manual online. Our measurements were made through the complete amplifier (aux input to output loads) with the tone controls and balance control bypassed. Relative to the amplifier's rated power, the S/N readings were -100 and -98 dB. With the 4-ohm series resistance and Sigma Drive off, the voltage at the speaker terminals varied about 2 dB over the range of frequencies up to 2,000 Hz.
