WE ARE AN AUTHORIZED KRELL DEALER!PREOWNED - $2500 LIST! - FULLY TESTED. INCLUDES ORIGINAL BOX/PACKING, MANUAL, REMOTE, POWER CABLE - ***VOLUME CONTROL ENCODER SOMETIMES BEHAVES IN A NON-LINEAR MANNER, but remote control operates the volume fine***The S-300i is the first Krell integrated amplifier to feature iPod connectivity and extends the award winning tradition of audiophile grade integrated amplifiers.A low profile chassis fronted by an elegantly finished silver Aluminum front panel hints at the potent circuitry hidden within its walls. Small in stature but big in performance, the S-300i integrated amplifier develops 150 W into 8 Ohms and 300 W into 4 Ohms. Employing a massive 750 VA toroidal transformer and 38,000 microfarads of capacitance guarantees huge power capability for maximum dynamic impact. Both balanced and single-ended inputs are provided, and the Theater Throughput™ mode, developed by Krell, simplifies integration into home theater systems. Robust WBT binding posts provide superior loudspeaker cable termination. New for the S-300i is direct connection for all generations of Apple iPods /iPhones with complete control of the iPod functionality via the included remote control. Unique for the category, the S-300i taps audio from the fully differential output included in the internal DACs of iPods/iPhones and maintains this balanced signal throughout the circuitry.The S-300i features the latest Krell Class A, direct coupled design, and fully balanced preamplifier circuitry for the lowest noise reproduction possible. Krell Current Mode provides unequaled bandwidth for the most revealing playback of todays high resolution music sources. Direct coupled circuitry eliminates impact-robbing capacitors from the signal path and an elegant, custom-machined level control adjusts volume.The included solid aluminum remote control replicates all front panel options as well as providing control for a connected iPod/iPhone. RS-232 is also included for inclusion in advanced control systems.Inputs1 pr. balanced via XLR connectors3 pr. single-ended via RCA connectors1 dedicated iPod input via 30-pin connectorOutputs1 pr. preamp outputs via RCA connectors1 pr. speaker outputs via gold-plated binding postsControl inputs1 RS-232 input via 9-pin D-subminiature connector1 remote IR detector input via 3-conductor 3.5 mm connector1 12 VDC trigger input via 2-conductor 3.5 mm connectorControl output1 programmable 12 VDC trigger output (30 mA maximum current) via 2-conductor 3.5 mm connectorInput impedanceBalanced: 95 k?Single-ended: 47.5 k?Frequency response20 Hz to 20 kHz +0, -0.14 dB<2 Hz to 110 kHz +0, -3 dBSignal-to-noise ratio>84 dB, wideband, unweighted, at maximum gain, referred to full power output>93 dB, A-weightedGain32.5 dBInput sensitivitySingle-ended or balanced: 800 mV RMSTotal harmonic distortion<0.035% at 1 kHz, at 150 W, 8 ? load<0.26% at 20 kHz, at 150 W, 8 ? loadOutput power150 W RMS per channel at 8 ?300 W RMS per channel at 4 ?Output voltage99 V peak to peak35 V RMSOutput current15 A peakSlew rate50 V/SOutput impedance<0.080 ? at 20 Hz<0.11 ?, 20 Hz to 20 kHzDamping factor>100 at 20 Hz, referred to 8 ?>75, 20 Hz to 20 kHz, referred to 8 ?Power consumptionStandby: 40 WIdle: 60 WMaximum: 1000 WHeat outputStandby: 140 BTU/hrIdle: 210 BTU/hrMaximum: 1600 BTU/hrSpecifications for preamp only:Gain6.3 dB (single-ended)Volume controlCurrent-mode, 12-bit, discrete R-2R ladderInput overloadBalanced: 12 V RMSSingle-ended: 6 V RMSOutput overload8 V RMS (single-ended)Frequency response20 Hz to 20 kHz +0, -0.05 dB<2 Hz to 1.0 MHz +0, -3 dBTotal harmonic distortion<0.009%, 20 Hz to 20 kHz, at 2 V RMSSignal-to-noise ratio>85 dB, wideband, unweighted, at maximum gain, referred to 2 V RMS>94 dB, A-weightedDimensions17.26 in W x 4.09 in H x 17.70 in D438 mm W x 104 mm H x 450 mm DWeightUnit only: 42 lb [19.0 kg]As shipped: 51 lb [23.1 kg]
