User manual PEAVEY ACM 2 DATASHEET

[. . . ] Protect the power cord from being walked on or pinched, particularly at plugs, convenience receptacles, and the point they exit from the apparatus. Note for UK only: If the colors of the wires in the mains lead of this unit do not correspond with the terminals in your plug, proceed as follows: a) The wire that is colored green and yellow must be connected to the terminal that is marked by the letter E, the earth symbol, colored green or colored green and yellow. B) The wire that is colored blue must be connected to the terminal that is marked with the letter N or the color black. C) The wire that is colored brown must be connected to the terminal that is marked with the letter L or the color red. [. . . ] Individuals vary considerably in susceptibility to noise-induced hearing loss, but nearly everyone will lose some hearing if exposed to sufficiently intense noise for a sufficient time. Government's Occupational Safety and Health Administration (OSHA) has specified the following permissible noise level exposures: According to OSHA, any exposure in excess of the above permissible limits could result in some hearing loss. Ear plugs or protectors to the ear canals or over the ears must be worn when operating this amplification system in order to prevent a permanent hearing loss, if exposure is in excess of the limits as set forth above. To ensure against potentially dangerous exposure to high sound pressure levels, it is recommended that all persons exposed to equipment capable of producing high sound pressure levels such as this amplification system be protected by hearing protectors while this unit is in operation. Three fully independent channels (clean/passive EQ, lead/passive EQ, and ultra/active EQ) give you a sonic palette that lets your imagination run wild. From the sparkling clean tones of the "vintage" mode to the nearly uncontrollable scream of the "ultra" mode to the extreme flexibility of new TransTube power amp damping and power level switches, the ACM 2 COMBO is sure to leave you mesmerized every time you plug in. Capable of over 100 Watts of earth shaking power into its two 12" Blue Marvel speakers (or any standard guitar cabinet), this behemoth can blow the roof off the largest of venues or. With a twist of the master volume and a flip of the 25/50/100 Watt power level switch, keep a crowd in the smallest of settings. Further tonal mayhem can be accomplished with outboard effects via the footswitchable effects loop. reverb is also included to put the icing on the cake. We've even thrown in a free heavy-duty metal footswitch and a classic jeweled pilot light so that you will certainly have the tools to break ALL of the rules. A higher damping factor (TIGHT) reduces cone vibration more quickly than a lower damping factor (LOOSE). This switch works much like the Resonance and Presence controls found on other Peavey amps, if they were to be turned simultaneously. If the Damping switch is changed, the volume level of the amp will also change and may require re-adjustment of the Master Volume (3). POWER This three-position switch selects the power output level of the power amplifier. Dynamics® control found on other Peavey amplifiers which provides for a more pronounced tube power compression simulation at lower settings. The CABINET IMPEDANCE switch (28) must be set to match the load of the speaker cabinet(s). cABINET IMPEDANCE This three-position switch allows for appropriate selection of speaker cabinet impedance. If two enclosures of equal impedance are used, the switch should be set to half the individual value. For example, two 16 Ohm enclosures necessitate an 8 Ohm setting, while two 8 Ohm enclosures would require a 4 Ohm setting. This switch should be set to 16 Ohms when no external cabinet is connected. GROUND POLARITY SWITCH This three-position rocker switch should normally be placed in the center (0) position.
