User manual CARVIN STX125

[. . . ] INPUTS Three Standard Phone Plugs are located on the left side of the chassis. The top jack is the input to Channel 1 while the bottom jack feeds Channel 2. The center jack allows one instrument to be fed into both channels simultaneously. Note that the center jack is active only when the other two jacks are unused. 2. [. . . ] GROUND When the amplifier is plugged into a properly wired 3-conductor outlet, this switch has little or no effect. However, if an older 2conductor outlet must be used with an adaptor, the GROUND Switch should be set to produce minimum hum and/or string "clicks". 9. POWER The POWER Switch is pushed to the right to turn the unit on. a. n. a. n. a. o. aA Parallel 1~, &, ~ an. . FUSE HOLDER Access to the fuse can be gained by pushing the fuse-holder inwards, then turning counterclockwise. If the second fuse fails, then a problem is indicated, and the amp should be serviced. To prevent unnecessary damage to the amplifier, NEVER USE A FUSE WITH A HIGHER RATING. 2. LINE CORD All Carvin equipment is supplied with 3-conductor line cords ending in grounding-type plugs. This arrangement will greatly reduce the possibility of electrical shock, provided the equipment is used with 3-conductor grounding-type outlets, and provided these outlets have been properly wired. If, at any time, electrical shock is experienced, disconnect the amplifier and have a qualified technician correct the trouble. Carvin does not recommend the use of the older, 2-conductor non-grounding type of outlets, as there is an increased danger of electrical shock. If this type of outlet is unavoidable, setting the GROUND switch for minimum hum will also minimize the possibility of such shock. 3. STANDBY SWITCH (Tube Model) Pushing the switch down places the amp into a Standby Mode. This switch removes the plate voltage from the tubes, leaving only the filiments on. In this way the amplifier is effectively shut-off but ready for immediate turn-on without waiting forthe filiments to warm up. CHANNEL SWITCHING (FS-34 Foot Switch) (Important: The Reverb will not function if the Foot Switch is not plugged in and de-pressed on). Your amp includes the FS-34 Foot Switch which offers visual monitoring of both channels. Connect the FS-34 by inserting the Chrome Plug into the top jack and the Black plug into the bottom jack as indicated on the rear pannel. Make certain that you plug the instrument into the center jack for switching Ch to Ch. CHANNEL INTERRUPT Each channel features a dual-circuit switching jack to provide interrupt access in each channel. Full break-outlbreak-in capability is available when a dual-circuit (stereo) plug is used. This allows external processing units (such as didital delay lines, paramtric equalizers, compressors, etc. ) to be patched-in as desired. The tip terminal of the jack must be wired to the unit's input, and the ring terminal wired to the unit's output. [. . . ] Channel 2 should be used as the Treble (Hi Pass) Amp in which the built-in power amp and speakers will function fine for that purpose. EQUALIZER SETTINGS Everyone will desire their own settings. However, keep in mind that Channel 1 (Lo Pass) should have all bass frequencies turned up and treble frequencies turned down. Likewise, Channel 2 (Hi Pass) should have all bass frequencies turned off and high frequencies turned up. AMPLIFIER SPECIFICATIONS VTX100 TUBE SPECIFICATIONS: TUBES: 4 EL34/6CA7's & 1 12AT7.
