The REX 3 all-triode power amplifier is the culmination of this work; a symmetrical single-ended bridge design using four of BAT’s signature triode 6C33C tubes with zero global feedback and an extremely short signal path that maintains a linear response in both frequency and phase domains.\u003c\/p\u003e\n\u003cp\u003eThis factory-configured monoblock pair offers 160 W per channel with each amp running in full triode mode. The custom-made output transformers are made to BAT’s exacting specifications, and have a wide-bandwidth frequency response from 5 Hz up to 300 kHz. The result is a presence and openness you can hear right from the opening note. \u003c\/p\u003e\n\u003cp\u003eAn intelligent automatic-bias circuit adjusts for changing line voltage and aging tubes, with LEDs showing the status of each tube. An ingenious fuse-less protection circuit eliminates power-supply rail fuses for better sonics and ease of use.\u003c\/p\u003e\n\u003cp\u003eThough a triode, the 6C33C-B output tube offers many times the current delivery of the 6550 tubes commonly employed in push-pull designs. Also, the high impedance of the 6550 tube requires far more complicated output transformers than the low-impedance 6C33C-B type. This allows BAT to spend money on sheer transformer tonnage and quality, and means the REX 3 is comfortable driving low-impedance loads.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eOutput Per Channel (8 Ω\/4 Ω):\u003c\/strong\u003e 160 W\/160 W\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eInput Impedance:\u003c\/strong\u003e 108 kΩ\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eGain (Nominal into 8 Ω):\u003c\/strong\u003e 26 dB\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eTube Complement:\u003c\/strong\u003e 4 x 6H30, 6 x 6SN7, 2 x 6V6, 4 x 6C33C-B\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003ePower Consumption (Idle\/Full Power):\u003c\/strong\u003e 500 W\/1,000 W\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eDimensions: \u003c\/strong\u003e17\" x 9\" x 24\"\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 100 lb\u003c\/p\u003e","brand":"Balanced Audio Technology","offers":[{"title":"Black","offer_id":32504295653436,"sku":"REX3-MONO-PR BLK","price":50000.0,"currency_code":"USD","in_stock":false},{"title":"Silver","offer_id":32504295686204,"sku":"REX3-MONO-PR SIL","price":50000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1564\/1247\/products\/BAT_monopower_blk_1024x1024_0970f716-0c14-4ad1-b734-28610b8eb683.jpg?v=1741631216","url":"https:\/\/upscaleaudio.pro\/products\/balanced-audio-technology-rex-iii-monoblock-power-amplifiers-pair","provider":"Upscale Audio","version":"1.0","type":"link"}
