{"product_id":"benchmark-media-la-4-preamplifier-8","title":"Benchmark Media LA-4 Preamplifier","description":"The Benchmark Media LA-4 preamplifier features a 100% analog fully-balanced signal path, a 256-step relay attenuator in 0.5 dB increments, a 0.1 Hz to 500 kHz frequency response, two balanced XLR and two unbalanced RCA inputs, buffered XLR\/RCA outputs, a mono sum output, a color touchscreen, and bidirectional 12V triggers. This line-level preamplifier is engineered for absolute signal purity. Utilizing gold-contact relays and laser-trimmed resistors, it eliminates the noise and channel-imbalance of traditional volume controls. Its compact chassis houses independent channel attenuators for perfect tracking, while the touchscreen allows for seamless input naming, balance control, and source gain offsets.  \n\nReviewers praise the LA-4 for its unprecedented transparency, calling it a flawless \"straight wire with gain\" that adds no electronic fingerprint. Critics note that it uncovers deep micro-detail and delivers a vast, three-dimensional soundstage with fast transients and perfectly timed bass. It scales beautifully at low volumes, preserving dynamic contrast without sounding sterile, while the silent operation of its stepped relay volume control is highly celebrated.  \n\nIntegrating this preamplifier optimizes your system's gain structure, allowing the true voice of your source and amplifier to shine completely unrestricted. Its ability to pass an uncolored signal ensures every musical nuance is revealed with lifelike accuracy. For anyone seeking a precise analog control center with absolute sonic honesty, this component represents the definitive endpoint for pure, distortion-free musical enjoyment.","brand":"Benchmark Media","offers":[{"title":"Default Title","offer_id":67602403918105,"sku":"100035","price":2299.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0844\/4225\/1545\/files\/100035-4.jpg?v=1790731799","url":"https:\/\/tmraudio.com\/products\/benchmark-media-la-4-preamplifier-8","provider":"The Music Room","version":"1.0","type":"link"}
