A Message from Genesis The transparency, detail retrieval, macro- and micro-dynamics, and wide frequency extension of Genesis loudspeakers place great demands on the quality of amplification. Hence, to match the Genesis loudspeakers, the Genesis Reference Series of amplifiers was created as the finest musical amplifiers available. The Genesis Reference Amplifier, together with a pair of Genesis loudspeakers, will give your entire music collection a whole new life. In a well set-up sy

Set-up and Safety Information Now that you have your new amplifier, we realize that you can't wait to hook it up and start playing! However, please read this set-up guide and safety information before you proceed. Unpacking and Setting Up The amplifier is likely to come in parts – the amplifier module, an acoustic suspension, and a power transformer (an auxiliary power supply upgrade called the Maximum Dynamic Headroom Reservoir is also available) unless your dealer has assembled it fo

Once you decide on the placement of the amplifier module, and connect the power transformer using the supplied Power Umbilical, locate the power transformer module as far away from the listener as possible. The Power Umbilical will only go in one way so the assembly should be obvious. Align the plugs to the like-colored sockets, insert and twist until the lock “clicks”. If you have the optional Maximum Dynamic Headroom Reservoir (MDHR), 2 place that on top of the amplifier module , and c

4. Before turning the amplifier on, both inputs and outputs should be properly connected. Do not run the amplifier without the appropriate loudspeakers connected to it. 5. While the Genesis Reference Amplifier runs very cool due to its high efficiency, some ventilation and airflow at the faceplate is necessary for reliable operation. Do not obstruct the vents at the sides of the chassis, or the holes on the bottom cover. 6. Do not connect or disconnect the loudspeakers from the amplifier

Set-up and Operation Speaker Connections A pair of 5-way insulated binding posts is provided on the rear of your amplifier. While this allows bare wire to be used, we recommend that firstly banana plugs, or secondly spade lugs be used instead of bare wire. Make sure that your speaker cables are firmly connected to the correct speaker connections. The binding posts are ETI CablePods™ for improved signal transfer, enhanced sonic performance, and a faster, more direct connection. The po

The use of single-ended to balanced converters that simply short pin 3 to ground is not recommended as performance will be compromised. Some form of balancing adapter may be used, but the performance of the GR-Amp will be limited by the sonic quality of the device. A high quality single-ended to balanced converters such as the FM Acoustics FM214 can be used between your single-ended preamplifier and the GR-Amp. The single-ended version of the GR-Amp converts a single-ended input into

up almost instantly, and be ready to play the moment you turn it on. The “stay warm” circuits consume about as much power as a night-light. To turn the amplifier back to stand-by, flick the power toggle up. When you know that you will not be using the amplifier for a long period of time (for example when you go on a business trip or a vacation), please unplug the power transformer at the wall outlet.

About Your Amplifier Introduction The Genesis Reference Amplifier uses proprietary designs and circuits, high quality components, and state-of-the-art Class D amplifier modules to deliver sonic performance rivaling amplifiers costing much, much more. The design brief was to deliver a load-invariant, wide-bandwidth amplifier that would deliver the musicality, emotion, and tonal colors of a low-powered valve amplifier with the reliability, power, and control of a high power solid-state

extension and drive of high-power transistor amplifiers without the muscle- bound sound, and the elegance, emotion and tonal colors of flea-powered single-ended triode vacuum tube amplifiers without being weak or flaccid. The origins of the DPDS comes from the principles of tube amplifier design – some of the qualities of tube amplifiers were as much to do with power supply design as the choice of tubes over transistors. Because of the high voltages involved, tube amplifiers use relative

available into lower impedance loads and better micro-dynamics – one listener described it as “having cream in your coffee instead of non-fat soy”. 4 Silent Running Voltage Supply We recognized that published specifications for noise rejection of opamps and even discrete small-signal amplification circuits did not always tell the whole story. The problem is that Power Supply Rejection Ratio, or PSRR, is specified at one frequency – usually 1kHz, but the truth is that this rapidly gets w

It will not surprise many to know that the avoidance of loop negative feedback is the key to this design. Having established a design, the components used were individually selected by extensive and laborious listening test. A discrete design allowed that as each component can be hand picked to get the optimum result. Every component on the design was individually chosen, as was the grounding paths. Resonance and Vibration Control With all the emphasis on reducing noise from the power

Acoustic Suspension System A dedicated suspension system completes the resonance and vibration control design of the Genesis Reference Amplifier. It also facilitates the easy placement and location of the amplifier. Designed like the suspension system of a race car, the acoustic suspension is made of a solid acrylic suspension frame, neoprene shock absorbers, and steel spikes. It isolates the amplifier from floor- or structure-borne vibrations, and yet at the same time allows any vibra
