Six years ago Alpine made the proposition that ultrasonic components were important to audio reproduction. The implementation of our proposal was the DA-07, a unique D to A converter employing a new interpolation program. Since then we have continued to study the impact of ultrasonics. We introduced a D to A converter unit for car audio (model 3900), which employed this technology. But, it did not penetrate widely because of its size and cost. Success required integration. The new one-chip Fluency DAC (FEDAC) incorporated D/A conversion and DSP to fully implement the "Fluency" interpolation method without loss of audio performance. This paper describes the theory of Fluency interpolation, the history of integration, and the performance evaluation of the one-chip Fluency DAC.
This is for the legendary alpine 3900 dac/preamp, using quad 18bit burr browns. It has 3 optical inputs and 2 analog inputs, copper chassis
The 3900 is a high end D/A convertor which has seperate PCB's for both the analogue/digital section. Its also supposed to extend the frequency range past 20kHz and give a 'natural' sound. The D/A was intended for Class A amplifiers and has outputs for 'Front', 'Rear' & 'Non-fading'. It also has a Fixed level output RCA which we will cover later. The D/A can handle 32k, 44.1k (CD), & 48k (DAT) inputs
The 3900 can only accept a 'fixed' RCA input, so you need one of these decks for the analogue section to work correctly. If you stick a bog standard deck on without this feature it will not work - trust me I've tried it
The 3900 has 3 digital inputs which range from 'changer', 'master', & 'aux'. The 5959/5959s changers were the intended targets for the 3900 as they had digital outputs or 5959 using 4323 interconnector from digital coaxial to optical digital outputs.
The 3900 also utilitises an M-BUS connection which goes from the headunit straight into the D/A itself. This is so you can use the volume controller on the headunit to control the overall volume. The D/A also has an M-BUS out which then connects to the changer as normal to power it etc. The wiring diagram is on www.alpine1.com if you need any further clarification on this.
From then on you use the Front, Rear & Non-fading outputs RCA's which go to the amplifiers.
Saying all of that, you can still use the 3900 with todays headunits which utilise an optical out on the deck - with a few niggles might I add.
Lets say for example you have a 7998R - you can wire it directly from the optical out straight into the 'changer' digital input - be aware that you will have to use the 'fixed output RCA' on the D/A.
From the fixed D/A output you will need a device to control the volume - Audiocontrol Master Volume Controller or something like a Three.1 will suffice as that has a line driver/EQ/crossover/volume control all in one..
From there you will just need to hook upto the amplifiers as normal and you're all done and dusted
I love the 3900 personally, I find the sound to be superior to the 7909 in most aspects but then again I love a 7909 in the dash lit up at night
I'll be using the 3900 with a 7939 Alpine deck when I get the optical cable to hook it up
