2HP-D Main Amplifier Operator’s Manual
Special order stainless steel front panel shown.

PREFACE
CONGRATULATIONS. You have just acquired one of the most advanced audio components ever
developed.
Your SAE 2HP-D was designed to set new standards in virtually every performance category. Not only does the 2HP-D
utilize a dual-differential balanced design, to our knowledge, it is the world’s rst amplier to be balanced both electrically
and physically. Each circuit board in the active signal path is designed with mirror imaged traces with the ground-point, the
fulcrum of the design, positioned at its absolute center.
Other signicant advances in the amplier include:
1. Dual mono design with separate and independent power transformers, power switches and line cords;
2. High temperature (Class F rated) toroidal transformers each with 1930 VA;
3. Separate and independent transformer windings for the input and output stages;
4. Independent transformer windings for each half of the balanced ampliers;
5. Independent bridge rectiers for each half of the balanced ampliers;
6. Four layer circuit boards used throughout; each with separate power and ground planes;
7. Mirror imaged board layout with a perfectly centered ground point. The circuit is both electrically and physically balanced;
8. Solid copper bus bar;
9. Current feedback for improved amplier control and virtually unlimited slew rate;
10. Double transistor input stage;
11. Dual-DC Servos virtually eliminate any DC offset;
12. ThermalTrak output devices optimize bias in real-time;
13. All protection circuitry is optically coupled and outside the circuit path. It is self-resetting;
14. Built-in distortion limiter compares amplier input and output and supply voltage to output voltage before engaging.
When engaged, amplier clipping is eliminated and THD cannot exceed 1%;
15. User selectable forced air (fan) cooling may be engaged or disabled as necessary.
16. Virtual VU and Frequency Spectrum Display Meters. These meters uniquely show the ampliers instantaneous peak
power output and average power output simultaneously without the inertia that causes inaccuracies in mechanical meters.

INTRODUCTION
Getting to know your SAE 2HP-D
This SAE 2HP-D amplier has been put through a rigorous and unique testing procedure that ensures that it will last for
many years with minimal service requirements. This procedure includes the following:
• All assembled circuit boards are given a thorough visual inspection and are then tested in a bench-reference amplier.
•The tested, assembled circuit boards are then installed in a new 2HP-D and the whole unit is tested for every function
and parameter.
•The unit is put on a burn-in torture rack to test for any possible component failures.
• The amplier then undergoes a critical listening and functional test.
•The unit has all remaining chassis components installed and then undergoes a complete visual inspection, which
assures that all SAE ampliers meet visual specications.
Burn-In/Break-In Time
This unit has a break in period of about 1 week during which continuous improvement in sound quality will be observed. It is
recommended that music be played continuously through the unit during this time to expedite the break in period.
Reference Manual Conventions
For clarity purposes, references to buttons and LED’s will be shown in bold capital letters.

IMPORTANT NOTICE
I. It is imperative that the SAE 2HP-D be connected to a ground via its three wire AC power cord. It is important that the
AC power outlet, which the amplier is plugged into, is actually grounded. Failure to do so will severely compromise the
performance, reliability and safety of use of the SAE 2HP-D.
II. Ventilation is an important issue when placing the SAE 2HP-D in a system. If the amplier is intended for passive (convection)
cooling, please make certain that it is placed in a well-ventilated area or rack unit. If the amplier will operated with fan
cooling, please allow space at the rear for heat to be discharged and cool air must be allowed to enter the amplier.
III. Please take note that powerline conditioners are not generally recommended for use with the SAE 2HP-D. If it is your
intention is to plug the 2HP-D into a line conditioner, check with your dealer to make certain that the particular conditioner
that is intended for use DOES NOT DEFEAT THE AC GROUND on its AC outlets and that it is capable of 20A operation.
Otherwise, the amplier’s power output may be compromised.
IV. DO NOT remove any cover panels from the amplier as there are no user serviceable components inside. Refer servicing
and updating to qualied service personnel only.

OPERATION
Before turning on the 2HP-D, ensure that all precautions and warnings have been carefully reviewed and adhered to. Damage
to the amplier caused by improper operation, wiring and/or ventilation will not be covered under warranty and SAE will not
be liable for any consequential damage or loss.
Connecting your 2HP-D
With the 2HP-D’s rear panel main power switches turned off, connect the signal outputs of the preamp/processor to the
balanced input of the amplier. Connect the output to the input of the speaker that is intended to be driven.
Please refer to gure 5.
The 2HP-D has a second binding post output connector. This may to be connected to the second speaker input terminal on
your loudspeaker system (if available). If using this second speaker input terminal, please be certain to remove the metal
jumper between the woofer and high-frequency sections of your speaker.
Connect a 12V trigger source to the STANDBY trigger input of the 2HP-D to enable remote turn-on and turn-off.
Setup and Operation
Turn the output volume of the preamp/processor, or other source device, down all of the way.
Turn on 2HP-D’s MAIN POWER switches, located on the rear panel.
When the end of the switch with | indicating “ON” is depressed that half of the amplier is in the STANDBY mode. When in
standby, the amplier draws less than 1 watt from the wall outlet.
Touch the front-panel power button. Both the switch and the SAE logo illuminate. After a wait of about 45 seconds, the
soft-start turn-on sequence is complete and the amplier is ready for use.
Slowly bring the output volume of the preamp/processor up to an audible level.
Remote Triggers
When the rear panel STANDBY trigger jack receives a 5-12 VDC signal, the 2HP-D will change its state from standby to
operate. When the signal is removed, the amplier will return to STANDBY.
