Es befinden sich keine Teile darin, die vom Anwender repariert werden könnten. Reparaturen nur von qualifiziertem Fachpersonal durchführen lassen. ACHTUNG: Um einen elektrischen Schlag oder Feuergefahr zu vermeiden, sollte dieses Gerät nicht dem Regen oder Feuchtigkeit ausgesetzt werden. Vor Inbetriebnahme unbedingt die Bedienungsanleitung lesen. ENGLISH NPUT (1) This input will accept signals from all types of bass pickups. BRIGHT SWITCH (2) 3rovides a preset boost to treble frequencies. To activate, depress the switch to its "in" position. INPUT PAD SWITCH (3) Provided for instruments that have extremely high output, which can result in overdriving (distorting) the input gain stage. Depressing the switch to its "in" position reduces the level of the input signal by 10 dB. PRE GAIN (4) Controls the input volume level of the amplifier. LOW FREQUENCY EQ (5) An active tone control that adjusts low frequencies. OPERATION NOTE: Excessive EQ boost, especially of the low frequencies, increases the possibility of speaker damage and sacrifices valuable headroom. LOW-MID FREQUENCY EQ (6) An active tone control that adjusts low-mid frequencies. HIGH-MID FREQUENCY EQ (7) An active tone control that adjusts high-mid frequencies. HIGH FREQUENCY EQ (8) An active tone control that adjusts high frequencies. MASTER VOLUME (9) Controls the overall volume level of the amplifier. The final level adjustment should be made after the desired sound has been achieved. PREAMP OUT/POWER AMP IN (10) These jacks are provided for in-line patching of effects devices. To patch an effects unit, connect the Preamp Output to the Input of the device. Next, connect the Output of the device to the Power Amp Input (high-quality shielded cables must be used for these connections). The Preamp Output can also be used to route the amplified signal to a mixing console, tape recorder, etc. Connect the Preamp Output, using shielded cable, to an Input of the tape recorder, mixer, etc. This patch does not affect the operation of the amplifier. NOTE: The Preamp output level is approximately 1 volt RMS and is of relatively low impedance (600 ohms). Any effects device used in this effects loop must be capable of receiving 1 volt input and providing 1 volt output in order to properly drive the power amp. The Power Amp Input has an internal switch that disconnects the internal preamp. HEADPHONE OUT (11) This stereo jack allows the signal to flow to both sides of any stereo headset. When headphones are connected to the amplifier, the internal speaker is automatically turned off. NOTE: The headphone system will not work with headsets equipped with a mono phone plug. POWER LED (12) Illuminates when AC power is being supplied to the unit. POWER SWITCH (13) Depress the switch to the "On" position. The green LED will illuminate indicating power is being supplied to the unit. Back Panel: LINE CORD-120 V products only (14) A For your safety, we have incorporated a 3-wire line (mains) cable with proper grounding facilities. It is not advisable to remove the ground pin under any circumstances. If it is necessary to use the equipment without proper grounding facilities, suitable grounding adaptors should be used. Less noise and greatly reduced shock hazard exists when the unit is operated with properly grounded receptacles. LINE (MAINS) CORD RETAINERS (15) Allows storage of mains cable for travel.
