For sale is rare DENON DAP-5500 digital pre-amplifier with factory box in good working condition. This is 100VAC model from Japan and required step down transformer for North American market. All functions were tested. Unit have superior build and sound quality. Comes as pictured. Will be double boxed for the safe shipping. Guaranteed to be working on arrival. Sorry, no extended warranty for old electronic. Features1. Digital multi-interface/DAC sectionThe D/A conversion circuit uses a newly developed 16-bit 4D/A push-pull super linear converter method (patent pending) to reduce nonlinear distortion and noise, achieving a dynamic range of 97 dB or more and an S/N ratio of 110 dB. . Realizing a wide dynamic range and low distortion rate, which is truly the ultimate in digital audio.Equipped with 3 digital input systems that support optical input, it directly receives digital output from CD players, DAT, DBS tuners, etc., and also automatically selects the sampling frequency and demodulates it into a digital signal.Equipped with a digital IN OUT circuit for digital recording and playback, digital equalizer, etc.The digital filter uses a cascaded 4x oversampling filter to reduce ripple and remove image spectra over a wide band.A high-speed optical coupling isulator is used from the digital section to the analog section to block unnecessary noise.Equipped with our proprietary low-pass filter CALP (Computer Analyzed Linear Phase), it completely cuts ultra-wide band noise and converts it into a pure analog signal.Equipped with a DAC OUT terminal that allows the converter section to be used independently. 2. Audio sectionEquipped with a special 4-volume volume and a non-feedback UGI (Unity Gain Interface) amplifier with an amplification level of zero to achieve a low distortion rate (0.002%, 20Hz to 20kHz). Pure level control with no deterioration in sound quality and low impedance (10?) transmission have been achieved.Equipped with a wide band flat amplifier (16.5dB), it can supplement the total gain of the playback system. (ON-OFF)Equipped with 3 balanced line input systems and 2 tape recording/playback systems.Equipped with 600? balanced output. 3. Adopts a completely separated digital/analog chassis structure that eliminates noise interference in the power supply/mechanical section. By completely insulating the digital and analog chassis sections with an acrylic insulator, mutual interference between digital and analog is prevented .2 transformers and 2 power supply circuits completely separated from the power cord In order to completely separate each digital/audio section, the power supply section is completely independent by installing twin power transformers. Constructs two dedicated digital/audio power supply sections to eliminate interference with the audio circuit.Heavy duty dual compartment chassis structure.A strong chassis that prevents the inside of the cabinet from being affected by external vibrations.Amazing vibration absorption ability.HEX location insulator system consisting of four metal mounting feet.
