Resumen del manual
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 STAGEBOARD 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 device'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 "preamp" 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 separate 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 signal). 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 processor. 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). TUBE 50/100 - MANUAL TIP: If you choose not to connect a signal processor/effects device to the FX loop, you may instead then connect another instrument or tape deck. For instance you could connect another guitar, keyboards, drum machine, tape player, etc. for rehearsals or practice sessions. When you use the FX RETURN as a second input channel, the FX-MIX knob is used to balance the respective volumes of your guitar and the other connected signal source. Another option is open to you if you do not connect a signal processor: you can use the loop to activate an additional MASTER volume. Proceed as follows: • Activate the FX loop. • Dial in a separate MASTER VOLUME setting via the FX MIX pot (to the left towards DRY = volume down, to the right towards WET = volume up). • You can switch back and forth between the two MASTER VOLUMES via the FX footswitch. If you have installed the MIDI option, you can also activate the alternate MASTER VOLUME via a MIDI command. 3.5 USING MIDI MSM-1 socket and indicator notch. Once the MSM-1 MIDI Module has been installed, you can execute the majority of the switching operations via MIDI. Simultaneous switching of both the TUBE 50 / TUBE 100 and the multi-effects processor is the utmost in convenience - with a wealth of all-tube sounds. Installing the MSM-1 MIDI Module: NOTE: The MSM-1 Module must be installed by a qualified service technician. The following instructions apply to repair personnel only. • Unplug the mains cord and speaker cables from the amplifier. • Remove the MIDI Module port cover plate from the rear panel of the chassis. • Remove the amp chassis from the wooden cabinet. For the combo version, after unplugging the speaker cable, remove the four retainer screws at the top of the amp. For the head version, remove the front panel cover to access the chassis retainer screws. Make sure that you do not damage the reverb cable when you pull the chassis out. • Insert the included MSM-1 ribbon-cable connector plug in the MSM-1's socket so that the color-coded wire faces the notch on the socket. Note that the two ribbon-cable connector plugs face away from the module in different directions. Select the plug that allows for the shortest signal path. Ensure you do not bend the pins when inserting the plug. Insert the MSM-1 in the module chamber and fasten it to the chassis using the four screws that you removed from the cover plate. Ensure the electronic components and the module inscriptions on the rear panel are facing right- side up. Position of the sockets. • Plug the other ribbon-cable connector into the socket on the circuit board. Note the markings on the connector and ensure they face the grooved portion of the jack when you plug the connectors in. • Ensure the connector fits snugly and the connector markings match the jack's grooved portion. • Replace and fasten the chassis cover and insert all cable connections. • Once you have switched the amp on, all MIDI functions should be accessible immediately...
