BEFORE CONNECTING, READ INSTRUCTIONS Read all of these instructions !Follow all warnings and instructions marked on the product !Do not place this product on an unstable cart, stand or table. The product may fall, causing serious damage to the product! [. . . ] - Before removing the rear panel cover, make certain the mains cord is unplugged from the wall socket!- Use only matched pairs of power amp tubes. You may use 5881 (6L6GC-R) tubes instead of the 6L6GC tubes for an even heavier sound, but, again, only in matched pairs. - For tonal reasons, we distinguish between 12AX7A and E83CC preamp tubes. The E83CC is a high-grade version of the ECC83, a common tube in Western Europe. The E83CC tube is built by another manufacturer; it features a different design and subsequently sounds different. In principle, you may use certain tubes other than those specified on the chassis in a pinch, but TriAmp sound quality will not be at its full potential. - A hum adjustment must be made every time tubes are replaced. Activate AMP 2, CHANNEL B and AMP 3, CHANNEL B and set the lowest noise levels via the trimmer. 10 TRIAMP - Manual 6. 0 TROUBLESHOOTING TriAmp is not getting any power: - Check the mains cable to see if it is connected properly. Replace the fuse with another identical fuse. TriAmp is connected properly, but no sound is audible: - The amp is set to STANDBY. - One or several GAIN and MASTER controls are turned all the way down. - The FX-MIX control is turned all the way to WET but you have not connected a processor to the FX loop. Switch the FX LOOP off or turn the FX-MIX knob to DRY. Before you replace the fuse, examine whether the power amp tubes are defective. - After replacing the fuse, with standby off, turn on the power. Look for tube "flash" before fuse blows, indicating excess oxygen within the tube. This will show which power tube needs to be replaced. The FX LOOP is on when it shouldn't be. - The FX LOOP is deactivated when the front panel button, the STAGEBOARD button and the MIDI module switching function are off. If any of these three switches is on, the circuit is active. The sound is thin and muddy when the effects processor is active. [. . . ] Um die dabei entstehenden Phasenauslöschungen zu vermeiden den FX-MIX Regler voll auf "WET" drehen. Beim Benutzen des RED BOX DI OUT entstehen beim lautem Abhören bzw. bei lauter PA Rückkopplungseffekte, obwohl der Amp ganz leise ist: - Angeschlossene Lautsprecher wirken bei einem Röhrenamp als "Mikrofon". Drehe den Master des TRIAMP auf, und die Rückkopplung verschwindet. [. . . ]
