Rca noise

Concerto Features Two pairs XLR input connectors for balanced system configurations. Three pairs RCA input connectors for unbalanced system configurations. Two pairs of parallel, high-current, balanced line level preamplifier outputs to allow driving of external amplifiers, subwoofers, zones, etc. Fully-balanced transformer-coupled inputs provide universal compatibility with other components and eliminate ground loop noise and EMI. Fully-balanced circuit topology implemented on all inputs and outputs. Bypass function allows for transparent use in combination audio/home theater systems. Regulated, high-current, linear power supply provides stable operating voltage with the lowest possible noise and distortion artifacts under all operating and line conditions. Low power consumption permits constant power-up operation to eliminate warm-up time. Optical encoder type volume control maintains quiet, trouble-free performance and accuracy over the entire lifetime of the product. Dual range volume control allows large volume level changes when knob is rotated abruptly, yet allows small, precise volume level changes when knob is rotated slowly. Six function, hand-held infrared remote transmitter. Ultra-low resonance, structurally rigid chassis, precision-machined from a solid block of aircraft grade 6061-T6 aluminum. Optional plug-in phono cards (installed internally) convert Line Input 2 to high performance phono inputs. Three gain and loading options can accommodate moving magnet (MM), moving coil (MC) cartridge types and high output moving coil cartridge types.

The A100 Titan provides a minimum of 200 watts (100W per channel), power output from 8, KT66’s in Ultra-Linear (UL) – push/pull operation. The A100 Titan like it’s bigger brother also features a newly designed custom output transformer resulting in a rich sound stage but with an authority that belies its 100W. FEATURES USB b'&' S/PDIF input For the first time, we include an onboard 24Bit 192KHz Wolfson DAC for an extraordinary listening experience. DC Powered tube heater All tubes, except KT66, have DC stabilized heater circuits to reduce hum noise to a near in-audible minimum. Output transformer The Output transformer uses a Hi-Grade Iron-Silicon for superb frequency reproduction b'&' width. With this newly designed custom output transformer unique to the A100 Titan we are able to achieve a highly delicate b'&' precise sound reproduction faithful to the original recording. Mechanical chassis construction The power supply b'&' output transformers are held by an extremely rigid “H” structure that keeps the unit free from unwanted vibrations which further helps reduce unwanted noise to the tubes. Remote control Featuring a superb CNC machined case it has a soft button design, perfectly matching the aesthetics for the “ACTION” series. Feet Four CNC machined aluminum feet with an insert of natural rubber. The depth b'&' form of these rubber feet has been calculated to minimize vibrations of the amplifier in isolation from its surroundings. Binding posts Gold plated professional binding posts for a continued oxidization free connection further improve sound refinement. Sockets Gold plated ceramic sockets for a continued oxidization free connection further improve sound refinement. Components Components for the A100 Titan have been selected with great care throughout. Only the best available components are considered b'&' all must undergo an exhaustive analysis of their sonic influence prior to final selection. Selected tubes All tubes used are selected after 2 stages warm-up. A fully computer monitored machine controls the process b'&' at the end of this, selects the perfect tubes which are then matched for a perfect balance.
