User manual HUGHES & KETTNER TRILOGY

[. . . ] 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. [. . . ] For more on this, see also the section in chapter 5 entitled How to Prolong Tube Life. For utmost handling ease, use SmartLoopTM in combination with a MIDI-enabled multi effector. This lets you control all switchable functions of TrilogyTM via MIDI, specifically · 1 Programming Programming couldn't be any easier. If you want to save a configuration such as CRUNCH with BOOST, FX and SERIAL activated, simply arm TrilogyTM by briefly pressing the MIDI LEARN button (MIDI LEARN lights up), and then pressing the desired program number on your MIDI board (or other MIDI send control). The MIDI LEARN light extinguishes to indicate TrilogyTM has assigned this configuration to the program number selected on your foot board. Now when TrilogyTM receives a program change message via the selected MIDI channel (more on this below), the MIDI LEARN LED flashes briefly and TrilogyTM is configured accordingly. To discontinue programming without saving settings once MIDI LEARN is armed, simply press the button again. 2 Setting the MIDI Channel and Switching OMNI On/Off If you press and hold the MIDI LEARN button for more than two seconds when TrilogyTM is in normal operating mode, its LED animates. The flashing light indicates special programming functions are now assigned to the amp's buttons and LEDs: CLEAN Now serves as an up button. This option is a good choice if you're unsure which channel your foot board uses to send messages. 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. 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. Tubes show definite signs of wear when their service life is nearing its end. [. . . ] It is not permitted to use repaired fuses or to short-circuit the fuse holder. Surfaces which are equipped with the , , HOT" mark (Diagram 2, below), rear panels or covers with cooling slits, cooling bodies and their covers, as well as tubes and their covers are purposely designed to dissipate high temperatures and should therefore not be touched. You should therefore avoid the direct vicinity of loudspeakers operating at high levels. Caution: The unit mains switch must be in position OFF before the mains cable is connected. [. . . ]
