3.4 USING SIGNAL PROCESSORS

The TUBE 50 / TUBE 100 is equipped with a PARALLEL effects loop. The processed signal is mixed with the original signal so that the original signal is still audible during the brief interruptions caused by multi-effects processor switching. The FX-MIX knob controls the dry/wet mix.

NOTE: As a rule of thumb, the best method for using signal pro- cessors is to set the device so that it processes as much of the signal as possible, and then mix the original signal with the pro- cessed signal via the FX-MIX control to avoid the tone degradati- on often caused by effects devices.

Connecting signal processors:

•Connect the device's INPUT to the SEND jack and its OUTPUT to the amplfier‘s RETURN jack.

•Activate the FX LOOP via the front panel button or STAGEBO- ARD Switch 3.

•Adjust the FX loop's level to the signal processor's level. Press the -10 db switch for effects devices that are designed for guitar signals. If the switch is not pushed in, the signal level remains at line level for 19" rack-mounted processors. Check out the devi- ce's level LEDs.

NOTE: It is usually more difficult to determine proper levels for multi-effects processors featuring integrated "preamps." These do not allow direct access to the FX section, so the signal actually runs through two preamps. Effects processors without these "pre- amp" sections are more suitable for use in FX loops because the sound quality and dynamics are substantially better. However, if you own one of these compact devices, dial in the FX unit's most dynamic and cleanest sound. If you want to use any of the FX unit's "preamp" section sounds, we recommend you use a separa- te switcher/looper to switch back and forth between the two preamps. If you want to amplify only the processed sounds, you can eliminate the TUBE Series preamp from the signal chain by using the RETURN input only to route the FX processor's output signal to your TUBE 50 / TUBE 100.

•Regulate the relationship between the original and processed signal via the FX MIX pot located on the front panel (towards DRY = more original signal, towards WET = more processed sig- nal).

NOTE: Some signal processors cause phase cancellations that are detrimental to the overall sound. In this case, turn the FX control all the way to the right (WET). The effects loop now operates as a conventional serial loop, i.e. the volume relationship between the original and the processed signal must be adjusted at the pro- cessor. The same holds true if you want 100% of the signal to be processed (for instance for extreme delays and volume pedals in the FX loop).
