{"product_id":"trilogy-915r-preamplifier","title":"Trilogy 915R Preamplifier","description":"\u003cp\u003eThe 915R is Trilogy's statement preamplifier, in the range since 2018. Four 6H6П super tubes mounted on solid billets provide the voltage gain. A series of three transformers feeds the power supply, and the valves' high voltage supply is actively shunt regulated — the rail can both sink and source current, which keeps it stable and quiet. Output is by Lundahl transformers, and there are no signal coupling capacitors anywhere in the circuit.\u003c\/p\u003e\u003cp\u003eConnectivity is comprehensive. Six inputs (three RCA, three XLR) feed four outputs (two RCA, two XLR) plus one RCA record send; one of the single-ended inputs can also be used as a return channel. TASlink RJ45 sockets sit at the far right of the rear panel. The casework is machined from billet alloy, and the preamplifier is supplied as standard with the machined billet Personal Remote Control and a power cord.\u003c\/p\u003e\u003cp\u003eThe menu goes further than most. Beyond display brightness, custom input labels, per-input gain trims, film mode, security bonding, sleep countdown and timed system switch-on over TASlink, the 915R will show the valves' work hours, schedule on and off times for everything connected over TASlink, report the temperature of any connected Trilogy amplifier, and display a real-time bar graph of the current being supplied to the loudspeaker. An optional security PIN entered at start-up will render the unit unusable in the event of theft.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTopology:\u003c\/strong\u003e four 6H6П super tubes on solid billets; actively shunt regulated valve HT supply; three transformers; Lundahl output transformers; no signal coupling capacitors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInputs:\u003c\/strong\u003e 3 XLR 3-pin female (over 48 kohms); 3 pairs RCA phono sockets (over 24 kohms)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutputs:\u003c\/strong\u003e 2 pairs XLR 3-pin male; 2 pairs RCA; 1 pair RCA send (tape); 600 ohms output impedance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGain:\u003c\/strong\u003e 14 dB inputs to main outputs; 0 dB inputs to send\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency response:\u003c\/strong\u003e 20 Hz – 45 kHz +\/- 0.5 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhase:\u003c\/strong\u003e phase correct (non inverting)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupplied with:\u003c\/strong\u003e machined billet Personal Remote Control; power cord\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower consumption:\u003c\/strong\u003e 95 W maximum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions \/ weight:\u003c\/strong\u003e 465 x 450 x 117 mm \/ 19 kg\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Trilogy","offers":[{"title":"Default Title","offer_id":49211049345243,"sku":null,"price":30000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1363\/6553\/files\/Trilogy_Audio_April_2023-3.jpg?v=1788279983","url":"https:\/\/almaaudio.com\/products\/trilogy-915r-preamplifier","provider":"Alma Music and Audio","version":"1.0","type":"link"}
