[. . . ] CARVIN ENGINEERING DATA PB100/PB200 BASS AMPS OPERATING MANUAL RECEIVING INSPECTION--read before getting started INSPECT YOUR AMP FOR ANY DAMAGE which may have occurred during shipping. If any damage is found, please notify the shipping company and CARVIN immediately. SAVE THE CARTON & ALL PACKING MATERIALS. In the event you have to re-ship your unit, always use the original carton and packing material. [. . . ] It's like having someone constantly and instantly re-adjusting the volume of the amplifier to prevent distortion when the peaks occur. 3. PRE-SHAPING SWITCHES The pre-shaping switches are preset boost and cut equalization settings to enhance your sound. · LOW - With this switch in, the result is a strong punchy low end starting at 100Hz. · MID - The mid switch is a mid cut switch in both switch positions. With the mid pushed in, the cut is centered around 300Hz which enhances the deep bass and leaves the mids intact. For the slap player and anyone who wants tight lows and bright mids and highs this is the desired position. With the mid left in the out position, the cut is centered around 500Hz and produces a brighter more common bass amp sound for the player who uses a pick or is light on the fingers. · HI - The Hi switch is a treble boost for frequencies above 6k Hz. This switch is for player who wants a bright fret clicking sound. 4. BASS AND TREBLE TONE CONTROLS The BASS and TREBLE tone controls are custom shaped controls to deliver punchy lows and crisp tight highs for a variety of bass sounds. When the BASS control is turned to the right, it boosts the signal and when turned to the left cuts the signal. The effected frequencies are centered at 80Hz and can deliver a great deal of volume. Be careful not to distort the low end, especially with the LOW pre-shaping switch pushed in. When the TREBLE control is turned to the right, it boosts the signal and when turned to the left, it cuts the signal. The boosted frequency for the TREBLE control is centered at 8k Hz. 7. NOISE GATE The noise gate may also be a new feature to some people, but it is a fairly simple tool for reducing pickup hum noise or any other noise on the input of the amplifier when the player is not playing. Think of the gate functioning like a door or (gate) at the input of the amplifier. When no input signal is detected the volume shuts down (as if a gate closes), therefore eliminating any noise picked up from entering the amplifier. Then when an input signal is detected, the volume is restored instantly (as if a gate was PB100 1 2 3 4 5 4 6 7 9 14 10 11 12 13 SUGGESTED SETTINGS PB100/PB200 STANDARD FINGER BASS 3 6 9 12 12 0 3 6 9 6 9 12 12 The following are suggested settings for common bass sounds and styles.

[. . . ] If a dark brownish color or no wire can be seen within the glass tube, then replace. The amp may be perfectly fine but occasionally a fuse may blow because of high AC voltage surges. After the fuse has been replaced with the proper Slow Blow value and if the fuse fails again, the amp will require servicing. 2) NO OUTPUT with POWER LED light ON Check the speaker cable. [. . . ]
