Descripción
- Four completely separate sets of transformer windings to power the four main preamp sections: moving coil, moving magnet, line, and display control. An additional 15 independent power supply regulators work in concert to eliminate ground loops and power supply noise.
- Optional phonostage: RIAA equalized, completely separate circuits for both MC and MM cartridge sources. Each circuit has its own set of direct outputs which bypass the internal switching and each has a dedicated user-selectable low cut filter.
- Highly configurable, sophisticated Menu system to tailor virtually every parameter of Ambrosia’s robust feature set to your satisfaction.
- A total of nine pairs of inputs:
- Three main inputs (CD, TUN, AUX)
- Two tape loop inputs
- (Optional) phonostage inputs, one each for MM and MC
- One combination XLR jack that can be used balanced or unbalanced
- Home Theater Bypass input
- Outputs: Two pairs unbalanced and two pairs balanced.
- Two headphone output jacks on the front panel powered by a unique, balanced power buffer idling at 4.5 watts per channel, capable of driving virtually any pair of headphones. The top output is a “switched” output: while in use, the Ambrosia will mute the line output to the connected amplifier.
- Fully balanced design with a sophisticated circuit that generates almost no distortion. Moreover, all of the distortion by-products in the Ambrosia come only from the passive switches and volume control, which are virtually inaudible.
- Highly customizable bass and treble controls.
- 14 gauge robust powder coated steel chassis and anodized aluminum front panel.
- Large, easy-to-read front LED display.
- Optional custom, solid aluminum remote control allows for all of the functionality available on the front panel.
