KH Klein+Hummel O 800 Active Subwoofer Designed In Germany Made In Ireland Used, Working Perfectly, Woofers are in perfect condition, Cabinets may have some signs of cosmetic wear Power cord included This active subwoofer is provided in the familiar form of a cuboid with a front-facing driver and an elongated horizontal slot vent near the base of the front baffle (the vent is actually divided in two). The cabinet has an internal volume of 59 litres, measures 360 x 320 x 510mm (hwd), and weighs a surprising 25kg. The maximum SPL is rated at 115dB at one metre and the response quoted as 30 to 90Hz ±2dB — making it an ideal match for the O 300 nearfield speakers.The units I/O is arranged in a vertical strip on the rear panel (which also carries a huge heat sink) with three XLR inputs. These each have a corresponding XLR output which feeds high-pass filtered versions of the signals on through to the appropriate satellite speaker. The filtering is performed by 24dB/octave Linkwitz-Riley filters set to 90Hz. The integral bass-management filtering can be disabled, though, either via a rear panel switch or, more unusually, via a footswitch connected to a dedicated quarter-inch socket. This function also mutes the subwoofer output, enabling a reliable now you hear it, now you dont comparison to be made with and without the subwoofers contribution.This whole I/O arrangement is very flexible and can accommodate a variety of system configurations, including 1.0, 2.0, 2.1, 3.0, 3.1, 5.1 and so on. In many instances the three inputs will be used to handle conventional left, centre and right inputs, filtering the satellite feeds and routing the bass content of all three channels to the subwoofer. Alternatively, the centre channel can be switched to operate as a direct LFE input. In this case, the centre input channel is routed to bypass the internal 90Hz low pass filter (although the bass elements from left and right inputs continue to be processed as before), enabling the user to establish any upper-frequency limit for a bespoke LFE input signal that may be desired.The three inputs are set up for nominal +6dBu sensitivity again, with an adjustment range for the derived subwoofer level of 18dB. The integral 120W amplifier has sophisticated built-in protection systems which ensure the longevity of the unit regardless of abuse, and a ground-lift facility controlled through another rear-panel switch helps to avoid potential hum loops.While the upper-frequency limit of the subwoofers signal is normally set to 90Hz internally, the lower frequency limit is adjustable with a four-position switch offering settings of 30, 40, 50, or 60Hz with a third-order slope. This facility is intended to help fine-tune the units integration into the room. A continuously variable phase control (zero to 180 degrees) is also provided, and the whole alignment process is aided considerably by the inclusion of a special test CD with various band-filtered pink noise signals.The single 16? driver is another custom design, with a long ±20mm throw and a 2165mm-diameter cone constructed from a high-tech Nomex/Kevlar composite material. The unit is also magnetically compensated, and is protected by a removable metal grille similar to that of the O 100. The cabinet shares the same charcoal-grey paint finish as the O 300 too, but is constructed from MDF rather than the exotic composite used in the satellites.Technical specifications O 800 Maximum sound pressure level in half space, 3% THD at 1 m distance 111.8 dB/SPL averaged between 40 Hz and 90 Hz Free-field frequency response 30 Hz - 90 Hz (+ 2 dB) in Sub-Direct mode Self generated noise level at 10 cm < 20 dB(A) THD @ 95 dB/SPL/1 m < 0.5 % above 30 Hz Amplifier Power amplifier section 120 watts into 16 Ohms (THD < 0.1 %) Crossover Crossover point 90 Hz Slope 24 dB/octave Limiter prevents overloading of loudspeaker and amplifier Inputs Left – Center (or LFE signal) – Right Impedance > 20 kOhm (electronically balanced) Subwoofer sensitivity - 6 dBu (0.388 V) CMRR > 50 dB Subwoofer Level Control 0 ... -18 dB Outputs Left – Center (or LFE pass-through) – Right Impedance 100 Ohms (electronically balanced) Frequency range 90 Hz - 30 kHz or linear (in Bypass position) Level same as input signal Low-cut filter 4-position switch 30 – 40 – 50 – 60 Hz with 18 dB/octave Phase infinitely variable 0 - 180° Ground lift switch separating signal ground from chassis ground Center-Mode – Sub Direct for Dolby 5.1 LFE Normal – Bypass Woofer 265 mm (10”) Ø, 16 Ohm, cast iron chassis Magnetic shielding standard Connections Mains power 3-terminal Euro-norm NK10 Amplifier Inputs 3 x XLR 3-31 (3-pin female jack) Amplifier Outputs 3 x XLR 3-32 (3-pin male jack) Bypass Remote Control ¼” phone jack Power consumption At idle 15 VA Full output 200 VA Mains 230 or 117 or 100 volts 50/60 Hz depends on version Dimensions (W x H x D) 12-5/8” x 14” x 20-7/8” (320 x 354 x 530 mm) Net volume 32.3 litres Weight 55 pounds (25 kg) Cabinet MDF; with metal grille dark grey enamel finish, color: RAL 7021 WE ARE LOCATED IN SIMI VALLEY CALIFORNIA.

Ich verkaufe einen Klein&Hummel V112-S Röhrenverstärker. Obwohl der Gesamtzustand gut ist, muss ich ihn als defekt verkaufen. Der Ausgangsübertrager fehlt !!!! Dieser wurde einst zur Reparatur eines anderen K+H Verstärkers gebraucht. Vor dem AÜ-Ausbau hat der Verstärker einwandfrei funktioniert. Alle Röhren sind vorhanden. Und ja, da wo die ECC808 hingehört, da ist auch eine :-) Ebenso sind alle Schrauben vorhanden. Ich verkaufe den Verstärker als Bastlerware und defekt. Keine Garantie! Versicherter Versand ist natürlich via DHL möglich :-)
