Ultra-fast-switching GaN transistors, paired with carefully tuned signal modulators and driver stages, deliver 50W per channel into 8 ohms in stereo, or 120W of true balanced power in bridge mono, stable down to 2 ohms. Balanced XLR and RCA inputs, triple-layer protection and a fan-free anodised aluminium chassis complete a remarkably versatile amplifier, available in black and gold or silver and gold.\u003c\/p\u003e\n\u003ch3\u003eThe Hi-Fi Centre Team Take\u003c\/h3\u003e\n\u003cp\u003eThe Crescendo CHORUS brings the speed, transparency and resolution of LAiV's GaN amplification to a truly accessible price, and it punches well above its size. Music is clean, open and dynamic, with tight, controlled bass, natural tone and a sense of effortless detail that belies its compact chassis. It is just as at home driving bookshelf speakers in a desktop system as it is anchoring a compact two-channel setup, and it pairs beautifully with LAiV's Crescendo VERSE DAC. For those who want to go further, adding a second CHORUS and running both in bridge mono creates a true dual-mono system with 120W per channel and complete channel separation.\u003c\/p\u003e\n\u003ch3\u003eKey Acoustic \u0026amp; Design Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGaN Amplification Derived from the Harmony GaNM:\u003c\/strong\u003e The same core Gallium Nitride technology as LAiV's Harmony GaNM switches at ultra-fast speeds for an output virtually indistinguishable from the original analogue waveform, with lower distortion, wider bandwidth and higher efficiency.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStereo \u0026amp; Bridge Mono Modes:\u003c\/strong\u003e Deliver 50W per channel into 8 ohms or 80W into 4 ohms in stereo, or switch to bridge mono for 120W of true balanced output into 8 or 4 ohms from a fully differential architecture, stable down to 2 ohms.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTriple Protection \u0026amp; Always-On Design:\u003c\/strong\u003e DC offset, over-current and over-temperature protection with microcontroller startup verification safeguard your speakers, while the efficient, fan-free chassis acts as its own heatsink and draws under 20W at idle.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAuthorized Dealer Support:\u003c\/strong\u003e Hi-Fi Centre is an Authorized Dealer for LAiV, ensuring authentic products backed by full manufacturer warranty coverage, in-store demonstration and expert technical support.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand \u0026amp; Model:\u003c\/strong\u003e LAiV Crescendo CHORUS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComponent Type:\u003c\/strong\u003e GaN Stereo Power Amplifier with Bridge Mono\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmplifier Technology:\u003c\/strong\u003e Gallium Nitride (GaN) FETs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Output (Stereo):\u003c\/strong\u003e 50W per channel at 8 ohms; 80W per channel at 4 ohms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Output (Bridge Mono):\u003c\/strong\u003e 120W at 8 \/ 4 ohms; stable to 2 ohms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInputs:\u003c\/strong\u003e XLR balanced (approx. 94 kohms), RCA single-ended (approx. 47 kohms)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput Sensitivity:\u003c\/strong\u003e 1.414 Vrms (XLR stereo), 1.100 Vrms (XLR mono), 0.707 Vrms (RCA stereo), 0.550 Vrms (RCA mono)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGain:\u003c\/strong\u003e 22 dB (XLR stereo), 28 dB (XLR mono), 28 dB (RCA stereo), 34 dB (RCA mono)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutputs:\u003c\/strong\u003e Speaker binding posts for two channels\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e 20 Hz - 80 kHz (±3 dB)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTHD+N:\u003c\/strong\u003e \u0026lt;0.005% at 5W into 8 ohms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSignal-to-Noise Ratio:\u003c\/strong\u003e ≥100 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDynamic Range:\u003c\/strong\u003e ≥100 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDamping Factor:\u003c\/strong\u003e Approx. 200 at 1 kHz into 8 ohms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtection:\u003c\/strong\u003e DC offset, over-current, over-temperature, microcontroller startup check\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFirmware Updates:\u003c\/strong\u003e Via microSD card\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Supply:\u003c\/strong\u003e 100 - 260V AC, 50\/60 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Consumption:\u003c\/strong\u003e ≤0.5W standby; ≤20W idle; ≤160W maximum output\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Black and gold, or silver and gold anodised aluminium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (W x D x H):\u003c\/strong\u003e 168 mm x 180 mm x 60 mm (70 mm with feet)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.5 kg\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eShould I use stereo mode or bridge mono mode?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eStereo mode is the plug-and-play choice for most systems, delivering 50W per channel into 8 ohms from a single unit. Bridge mono mode converts the input into a fully differential, true balanced signal and combines both channels to deliver 120W into a single speaker, with improved noise rejection and dynamic range. For the ultimate performance, LAiV recommends pairing two CHORUS units in bridge mono, one per channel, for complete left and right separation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I need a preamplifier to use the Crescendo CHORUS?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. The CHORUS is a power amplifier without volume control, so it needs a preamplifier or a DAC or streamer with variable output. It pairs naturally with LAiV's Crescendo VERSE DAC but works with the vast majority of DACs and preamplifiers on the market. For best performance, LAiV recommends the balanced XLR input, which offers lower distortion and noise.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I leave the Crescendo CHORUS switched on?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. The CHORUS is engineered for always-on operation, using under 20W at idle and 0.5W or less in standby. Thanks to the efficiency of GaN technology, the chassis acts as its own heatsink and stays only lukewarm during normal use, with no fans required. When powering up, switch on your DAC or preamplifier first, then the CHORUS, and reverse the order when shutting down.\u003c\/p\u003e","brand":"LAiV","offers":[{"title":"Black","offer_id":67901576937525,"sku":"Crescendo Chorus-Black","price":1450.0,"currency_code":"CAD","in_stock":true},{"title":"Silver","offer_id":67901576970293,"sku":"Crescendo Chorus-Silver","price":1450.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2246\/9355\/files\/Crescendo_Chorus.jpg?v=1793812850","url":"https:\/\/hificentre.com\/products\/laiv-crescendo-chorus-stereo-power-amplifier","provider":"Hi-Fi Centre","version":"1.0","type":"link"}
