Page 6: Introduction
Introduction am·bro·sia \am-ˈbrō-zh(ē-)ə\ The food of the Greek and Roman gods. Something extremely pleasing to taste or smell or, in this case, to hear. The Ambrosia 2000 Second Edition preamplifier is a brilliant example of what a reference, full-featured, stereo preamplifier can be. This fully-balanced system nucleus features giant power supplies, an optional MM/MC phono stage, headphone amplifier, tone and balance controls and an ingenious remote control. Some recent improvements include redesigned internals for improved stability, lower noise and a new home theater bypass function. There are no physical switches or controls of any kind in the signal path; the user interface is all electronic and galvanically isolated from the audio circuit. All functions are 100% microprocessor controlled and can be controlled from both the front panel as well as the optional remote control. At 50 pounds, the Ambrosia outweighs many power amplifiers! Most of the weight is due to the huge low-EMI power transformer. It features four secondary windings that power each circuit section independently, and in the process, eliminate ground loops. In addition, 15 independent power supply regulators are employed throughout for immunity against AC mains fluctuations. Every attention to detail and function contributes to the final, undeniable conclusion: The Ambrosia is a sonic tour-de-force befitting the finest audio systems. © Spread Spectrum Technologies.

Page 7: Noteworthy Features
Noteworthy Features The Ambrosia 2000 Second Edition is a revolutionary preamplifier in many ways. Below are some highlights. ● 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. ... -
Page 8: Front Panel Button And Control Definitions
Front Panel Button and Control Definitions On/Off Switch Headphone Outputs The top output is a “switched” output: while in use, the Ambrosia will mute the line output to the connected amplifier. 3. LED Main Display Remote Control Sensor 5. “SEL”: Menu Select These buttons are used to cycle through the USER and MAIN Menus. It is a continuous scroll function in that upon reaching the end of either Menu, the next step starts back at the beginning. 6. “ENT”: Enter After deciding on a Menu option setting, you must push the ENT button to save that setting to memory. The only function that does not require this action is the volume control. After you have entered a setting, the Ambrosia display will revert to master volume. “MEM”: Memory This button allows you to get back to the last Menu option you were on, eliminating having to scroll through the Menu to get there . Ex: You saved an option for the BASL (Bass Left) position and the Ambrosia display has reverted to the master volume. Pushing the MEM button will now call up the BASL position. The MEM button recalls the last Menu position for which ENT was pressed. 8. “MUTE”: Mute Mutes the volume. 9. “ADJUST”: Shaft Encoder This is a multi-function control. Use it to scroll through the various options within a Menu position. It also controls the master volume, balance, bass and treble. © Spread Spectrum Technologies.

Page 10: First Time Operation And Making Menu Adjustments
First Time Operation and Making Menu Adjustments Before you turn on the Ambrosia for the first time, it is important that you read, understand and familiarize yourself with the following for optimal operation and enjoyment. Refer to the section “Front Panel Button and Control Definitions” for descriptions. First Time Operation ● IMPORTANT: Insert the supplied RCA shorting plugs into all of the unused input jacks, including the tape inputs . This will prevent audible clicks and pops while cycling through the Menu and open inputs. None of the inputs are internally shorted when not selected. If you do not use the shorting plugs, there is a chance that clicks and pops may cause speaker damage. SST will not be responsible for any speaker damage due to negligence in this regard. ● Ensure the Ambrosia is POWERED OFF before making or changing any input connections. Once connections are securely made, push the On/Off rocker switch to On. You will notice that the display shows the Initialization mode (“INIT”). It may take 30 to 40 seconds for the Ambrosia to initialize. After this first initialization period is finished, the display will read “VOL - 69.0” (the lowest volume setting). The Ambrosia will recall the last used volume level for each subsequent time it is turned on, or “- 15.0”, whichever volume level is lower. Making Menu Adjustments There are actually two Menu systems in the Ambrosia: USER and MAIN. USER is simply a condensed subset of the MAIN Menu, showing only the most oft-used positions. The following will help familiarize you with Menu operation and settings. For instructional purposes we will concentrate on the MAIN Menu, since it contains all the positions in the USER Menu. Refer to the next section, “Menu Selections”, for a complete list of the USER and MAIN Menu positions. ● Push the bottom SEL button to arrive at the SEL (Source) position. Turning the Shaft Encoder to the right, you can move through the various source options as follows: TUN, AUX, CD, BAL*, HT (Home Theater bypass), MC**, MM**. Push ENT to select your desired input. The main display will then revert to showing the volume. *BAL refers to the XLR “combo jack” input, which can be used as an additional balanced (or unbalanced via the supplied adapter) input. Note the Menu will always refer to this input as “BAL” even if used as unbalanced. ** If no phonostage is installed, these options will not appear in the Menu. ● Next, push the bottom SEL button until you arrive at MODE. Use the Shaft Encoder to choose one of three options: Stereo, Mono or Stereo Reverse. Note that MODE is a global setting, not unique to each Source ... - Page 11 ● The next Menu position is FILT (Low Cut Filter) and will only display with the optional phonostage installed. The options are None, MC, MM or MCMM (applies to both). The phono filters are set at approximately 20 hz. ● From here, pushing MEM and then the down SEL button will take you to LOFT (Low Frequency Turnover). There are four options possible. Be advised that these numbers only indicate the relative area of frequency turnover points. The same holds true for the next position, HIFT (High Frequency Turnover). There are four options available. For LOFT and HIFT, use your ears to determine which sounds best to you. ● Next is COPY (Tape Copy) which allows you to copy from one tape recorder to another. The positions are OFF, T1 >T2 or T2 >T1. ● The next option is TAPE (Tape Monitor). You can select either OFF, MON 1 or MON 2. ● The last Menu position is HTGA (Home Theater Bypass Gain). You can select either -14 or +0. Default is -14 for US units. All of these functions are mirrored in the available remote control and can be adjusted in the same way as above. © Spread Spectrum Technologies.
