User manual HUGHES & KETTNER TRILOGY 1.1

[. . . ] Complies with the provisions of the Directive of the Council of the European Communities on the approximation of the laws of the Member States relating to electromagnetic compatibility (EMC Directive 89/336/EEC) and the low voltage Directive (73/23/EEC). This declaration of conformity of the European Communities is the result of an examination carried out by the Quality Assurance Department of STAMER GmbH in accordance with European Standards EN 50081-1, EN 50082-1and EN 60065 for low voltage, as laid down in Article 10 of the EMC Directive. Even in the new millennium, classic rock, blues and metal sounds of last century's great guitarists continue to shape musicians and audiences' tastes in tone. Back in the day, flexibility wasn't top on the list of amp attributes: Two channels were standard, three a luxury, and four MIDI switchable channels a dream at best. [. . . ] The flashing light indicates special programming functions are now assigned to the amp's buttons and LEDs: CLEAN Now serves as an up button. SPARKLE Now serves as a down button with one-step increments (-1). This option is a good choice if you're unsure which channel your foot board uses to send messages. SERIAL: Press this button to check if all LEDs are working properly. All LEDs on TrilogyTM's front panel must light up for as long as you press and hold SERIAL. Never connect speaker cabinets with an impedance (ohm) rating lower than TrilogyTM is designed to handle. Never connect devices with high output signal levels (e. Check the mains power rating before plugging the amp in. When in doubt ask the venue's sound technician or facility engineer. Once they've been burned in ­ that is, operated continuously under a load ­ they are subjected to a rigorous selection process. Their electrical specs and mechanical status (microphonics) are checked, and then they are installed in an amp and soundchecked. One of the most important steps in this process is tube matching, whereby tubes with the same characteristics are teamed up in matched sets of power tubes. In the unlikely event that you encounter a problem, please run down the following checklist before you swap your old tubes for a new set: Was the fault or failure of the power tube caused by the tube itself or by a flawed peripheral device or component, perhaps a defective speaker cable?(If you don't get to the bottom of the problem and remedy it, it may crop up again even after you replace the tubes. Over-voltages are often caused by generators and faulty high-current power circuits. Perhaps a fuse blew even though none of the tubes is actually defective?An old fuse, tube de-ionization or mains voltage power surges may have triggered the fuse. In this case, replacing tubes is a waste of money, time and effort. Tubes show definite signs of wear when their service life is nearing its end. Telltale signs are increased microphonics, noise and hiss, muddier tone through loss of high-end frequencies, degraded performance, etc. Take these indications seriously and replace old tubes. Not only do these side effects take their toll on sound quality, they also indicate the aging tube will soon fail! [. . . ] The plug socket for the power supply must be positioned near the unit and must be easily accessible. pLACE OF INSTALLATION: · The unit should stand only on a clean, horizontal working surface. The unit must not be exposed to vibrations during operation. Keep away from moisture and dust where possible. [. . . ]
