A Message from Genesis The Genesis Integrated 60-Watt Valve (or vacuum tube) Amplifier is a limited-edition product that was created as proof of concept that a welldesigned, well-executed, value-priced amplifier will be able to drive any Genesis loudspeaker with ease and authority. The transparency, detail retrieval, dynamics, and wide frequency extension of Genesis loudspeakers place great demands on the quality of amplification.
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 Your amplifier is heavy, and its vacuum tubes are delicate and dissipate a great amount of heat. It is important that this product is never used near water or sources or water. Avoid bathrooms, washbowls, kitchen sinks, swimming pools, etc.
years of trouble-free service. Please see Adjusting the Bias and Replacing Tubes (pages 9 and 10) for special instructions. 3. Vacuum tubes dissipate a large amount of heat and will result in very high temperatures: a. Do not touch the tubes with bare hands during, and immediately after operation. It could cause severe burns. b. The I60 features a removable “tube cage”. However, we recommend that for the sake of safety, you operate the unit with the tube cage left in place. c.
About Your Amplifier Introduction The Genesis Integrated 60-Watt Stereo Valve Amplifier uses proprietary technology, high quality components, and state-of-the-art vacuum tube topology to deliver sonic performance rivaling other amplifiers costing much more. The design objectives of this product are to: 1. Deliver musically accurate amplification, 2. Provide a vacuum tube amplifier that would approach the reliability and ease of use of solid state amplifiers, and 3.
attenuator is employed as a volume control; low-noise gold plated militaryspec ceramic tube sockets are used throughout. Very little feedback is used – just enough to make the amplifier unconditionally stable. Not the excessive amount that is sometimes employed to make amplifiers measure better at the expense of musicality. During construction, all components are handselected and precisely matched.
check the specifications of your speakers. Speakers with 6 ohms up to 8 ohms impedance should be connected to the “8 ohm” speaker connectors. Genesis loudspeakers should be connected to the “4 ohm” connectors. Two sets of 5-way insulated binding posts are provided on the rear of your amplifier, but we recommend that you use spade lugs or banana plugs instead of bare wire. Make sure that your speaker cables are firmly connected to the correct speaker connections.
for their reliability and durability. Hence, your vacuum tube amplifier should give you years of trouble free service and magical musical moments. Controls Power Switch Turn the switch clockwise to turn the amplifier on. The blue power indicator will light up, and the tubes will begin to warm up. A soft start circuit is incorporated for extended tube life and to prevent a turn-on thump at the speakers.
Maintenance Periodically dust and clean your amplifier of the grime of daily living. Unplug your amplifier from the wall before cleaning. Do not use liquid cleaners or aerosol cleaners – just a clean, dry cloth. Do not use abrasive pads, scouring powder, or solvents such as alcohol. Adjusting the Bias Your amplifier should give you years of trouble-free service. Re-biasing the vacuum tubes will not be necessary unless you change the valves. However, we have provided a simple means to do it.
voltmeter (like the RadioShack pictured) don’t worry if you can’t get to exactly 2.00V. Plus or minus 0.05V is more than accurate enough! Once you have adjusted the bias of one tube, move the red probe to the other hole labeled (+) to adjust the bias of the other tube before moving to the other side of the amplifier to adjust the bias of the other channel.
