GamuT International A/S, Oesterled 28, Bygning A, DK-4300 Holbaek, Denmark Telephone no: int + 45 70 20 22 68 Telefax no: int + 45 59 43 97 26 www.gamutaudio.com Users Guide GamuT M250 Mono Power Amplifier SAFETY INSTRUCTIONS: - Never let children (or grownups) push anything into holes or slots in the case - this could result in an electric shock and could cause damage of the set. - Page 3 A CD player in repeat mode can speed up the process while you are not at home. Do not play too loud. After this break-in period is over, simply switch the GamuT on when you get home, and it will be ready to perform at its best after dinner.
- Page 4 The protection also detects too low impedance loads, and alerts the user by muting for a second. So the user can be sure to hear only clean non-distorted audio. The normal current limiting and momentary distortions of the music are avoided in the GamuT M250 power amplifier. A second of silence You may experience a second of silence while the music is playing loudly.
- Page 5 Unfortunately, some loudspeakers have an impedance, which is much lower than specified. They will not damage the GamuT power amplifier, because it will simply mute. In the GamuT M250 MkIII, we use a gem of a MOSFET transistor. It handles 500W, and a peak current of 400 Ampere and 100 Ampere long-term.
- Page 6 Only change a blown fuse once, and use the spare slow blow fuse located in the mains socket on the back panel of GamuT M250. Use only the special spare fuse in the fuse holder. For 230-240 Volt Mains use sand-filled 5 Ampere slow blow fuse type marked T5A...
- Page 7 If both channels are silent, but the blue power lights are on, you can check them in the following way: Switch off power and wait 10 seconds and then switch it on and listen carefully. There should be two quiet mechanical clicks coming from the inside of the amplifier. If not, disconnect the input cables and try again.
- Page 8 Interesting trivial facts It may interest you to know that the output voltage is 55 times the input voltage at maximum gain. However the input signal current in the 20kOhm RCA input is only 38.8uA at full power, and the output current is 10.7 Ampere at full power in 4 Ohm, as current gain is 275,000.
- Page 9 Recommended CDs This is a list some of the recordings that have been used to evaluate the sound quality of this amplifier. The LP version can be superior, but it is difficult to obtain. Most recording engineers today try to make the music sound fine on the cheapest stereo systems, simply because they are in majority and thus brings more sales of CDs.
- Page 10 This CD has been used at many shows, and it does not fail, many visitors ask for the label and number, so that they can go out and buy it. Finally, we wish you many years of enjoyment. With our best wishes, GamuT International A/S GM250MK3OW/2004...
