The team are dedicated to creating audio components that honour musical performances; through careful design, careful selection of the best components available and meticulous attention to construction. As a result they have created, quite possibly, an unrivalled line preamplifier in its class.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThe new ROMA117DC tube line preamplifier with its great tonal balance and refined reproduction is the perfect combination with the ROMA98DC mono power amps. The ROMA117DC matches the simple and elegant design of the rest of the ROMA Series. A product of great musicality for the most demanding music lovers.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eThe audio circuit consists of a two-stage amplification incorporating two Pairs of 6922 \/ ECC88 Tubes. The balanced and balanced inputs are managed through the use of an input tube. The output stage of the amplifier is made using an output transformer. A low output impedance makes the ROMA117DC extremely flexible in the choice of interconnect cables for connection to the final stages of power amplifiers. The frequency response is extremely linear and extended enough to reach 5 Hz - 40KHz at -3dB. The power supplies of both the filaments and the anodic are electronically regulated with a regulation better than 0.1%.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eThe ROMA117DC is supplied with a remote control that allows for volume adjustment and source selector. Electronic switches are located near the input connectors, keeping signal paths very short to minimise crosstalk between channels. In the audio circuit, only precision resistors a metal film and polypropylene capacitors are used. The tubes have been selected to ensure quality and minimise noise and microphonics.\u003c\/p\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eKey Features:\u003c\/h3\u003e\n\u003cul data-mce-fragment=\"1\"\u003e\n\u003cli data-mce-fragment=\"1\"\u003ePairs perfectly with the ROMA 98DC mono power amps\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eCarefully selected tubes for the best performance\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eAutomatic warm-up of 45 seconds\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eShort signal paths for reduced crosstalk\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eTrue Italian design with 3 decades of experience\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eTwo stage amplification\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eRemote control included\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eAvailable in 5 elegant finishes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eSpecs\u003c\/h5\u003e\n\u003cp\u003eTechnical Specifications:\u003c\/p\u003e\n\u003ctable border=\"0.5px\" class=\"table table-striped table-bordered table-responsive;\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eTubes Complement:\u003c\/td\u003e\n\u003ctd\u003e4 x 6922\/6DJ8\/ECC88\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInputs:\u003c\/td\u003e\n\u003ctd\u003e1 x unbalanced (XLR)\u003cbr\u003e4 x balanced (RCA)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Impedance:\u003c\/td\u003e\n\u003ctd\u003e100kΩ balanced (XLR)\u003cbr\u003e47kΩ unbalanced (RCA)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput (Transformer):\u003c\/td\u003e\n\u003ctd\u003e1 x balanced (XLR)\u003cbr\u003e2 x unbalanced (RCA)\u003cbr\u003e1 x unbalanced REC OUT (RCA)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency Response:\u003c\/td\u003e\n\u003ctd\u003e5-40 KHz (-3 dB)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTHD + N: (w,d,h):\u003c\/td\u003e\n\u003ctd\u003e\u0026lt;
