Rated at 75 W into 8 ohms, it is designed for systems where full-size power-amplifier performance is wanted without a full-size component footprint.\u003c\/p\u003e\n\u003cp\u003eBerTTi uses Chord’s latest ULTIMA dual-feed-forward topology, a circuit approach designed to monitor and correct the signal before the output stage. The result is a compact stereo power amplifier built around speed, low distortion, and control rather than brute-force size.\u003c\/p\u003e\n\u003ch4\u003eCompact ULTIMA Power\u003c\/h4\u003e\n\u003cp\u003eAs the most affordable ULTIMA-technology stereo power amplifier in Chord’s lineup, BerTTi carries technology derived from the company’s larger amplifiers into a more accessible and system-friendly form. Its fully balanced design, custom MOSFETs, and HF switch-mode power supply are all part of that approach.\u003c\/p\u003e\n\u003ch4\u003eBuilt for Table Top Systems\u003c\/h4\u003e\n\u003cp\u003eBerTTi is a natural partner for Chord’s Hugo TT 2 DAC\/preamp and Hugo M Scaler, creating a compact high-performance system with serious power amplification in the final stage. It also works as a standalone stereo power amplifier with any suitable preamp or DAC\/preamp.\u003c\/p\u003e\n\u003ch4\u003eBalanced and Unbalanced Connectivity\u003c\/h4\u003e\n\u003cp\u003eInputs include a stereo pair of balanced XLRs and a stereo pair of gold-plated unbalanced RCA connectors. The speaker outputs use gold-plated terminals, and a 12 V trigger input allows compatible partnering components to switch the amplifier on and off from standby.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e75 Wpc output into 8 ohms\u003c\/li\u003e\n\u003cli\u003eChord ULTIMA dual-feed-forward topology\u003c\/li\u003e\n\u003cli\u003eFully balanced design\u003c\/li\u003e\n\u003cli\u003eCustom-made MOSFETs\u003c\/li\u003e\n\u003cli\u003eHF switch-mode power supply\u003c\/li\u003e\n\u003cli\u003eTwo modified power supplies for increased performance\u003c\/li\u003e\n\u003cli\u003eAdditional auxiliary power rail for the front end\u003c\/li\u003e\n\u003cli\u003eStereo pair of balanced XLR inputs\u003c\/li\u003e\n\u003cli\u003eStereo pair of gold-plated unbalanced RCA inputs\u003c\/li\u003e\n\u003cli\u003eGold-plated speaker terminals\u003c\/li\u003e\n\u003cli\u003e12 V trigger input\u003c\/li\u003e\n\u003cli\u003eSolid aluminum chassis\u003c\/li\u003e\n\u003cli\u003eDesigned and handmade in the UK\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eIncluded Accessories\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBerTTi quick-start guide\u003c\/li\u003e\n\u003cli\u003eSafety instructions\u003c\/li\u003e\n\u003cli\u003e10 A mains IEC cable\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cp\u003e\u003cb\u003eOutput Power:\u003c\/b\u003e 75 W into 8 ohms\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003ePower Consumption (Full Power):\u003c\/b\u003e 240 W\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003ePower Consumption (Standby):\u003c\/b\u003e 1 W\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eFrequency Range:\u003c\/b\u003e 5 Hz–100 kHz, ±0.5 dB\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eTHD:\u003c\/b\u003e 0.008%\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eSignal-to-Noise Ratio:\u003c\/b\u003e 87 dB, A-weighted\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eInput Impedance:\u003c\/b\u003e 100 kΩ, unbalanced\/balanced\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eInput Sensitivity:\u003c\/b\u003e 0.78 V\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eGain:\u003c\/b\u003e 30 dB\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eDimensions (HWD):\u003c\/b\u003e 2.3\" x 9.3\" x 10.1\" (59 mm x 235 mm x 256 mm)\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eWeight:\u003c\/b\u003e 8.3 lb.
