Speaker Terminals Permit hook up of two stereo pair of speakers via the wire terminals. [. . . ] Speaker A/B Selector Switches Permit you to select speakers attached to terminal set A, set B, or both. Voltage Switch The amplifier has selectable input voltage from 110V/60Hz which is the standard in USA and CANADA. You can also switch the input voltage to 220V/50Hz for EUROPEAN operation. Please make sure the switch is in the proper position before operating, otherwise severe damage will result not cover by the warranty. Please also replace the fuse with proper rating in this situation (see the SPECIFICATIONS for the fuse rating). PYLE PRO PT-2400/2800 Amplifier Owner's Manual PYLE PRO PT-2400/2800 Amplifier Owner's Manual ­ 1 INSTALLATION GUIDELINES Connecting the GND (GROUND) screw terminal Connecting a mixer or preamplifier may cause excessive noise or hum in the amplifier output. To prevent this, connect one end of a low-capacitance shield wire to the amplifier's ground screw (on the rear panel). Then connect the other end of this wire to the ground terminal on the mixer or preamplifier enclosure. Stereo or Mono Inputs Your Pyle Pro amplifier can be operated in Stereo or Mono mode, depending on the input source. If the input signal is mono, connect the source via the LEFT input only (also marked "MONO" on the back of amplifier). Then slide the STEREO/MONO selector switch to MONO and the signal will be routed through both channels. Bridge Mode Operation This amplifier can be operated in mono bridged output mode, if your speakers can handle the following power output levels: PT2800: 370 watts PT2400: 230 watts As shown in the diagram below, connect the speaker's positive (+) to the amplifier's red speakers left (A/B) terminals and negative (-) to red speakers right (A/B) terminals. The speaker righr (+) on the amplifier is used a negative (-) terminal for a bridged connection. Using the power meter The meter LED dispaly position indicate the amplifier output power. Using the left and right Output Level controls Rotate output level gain clockwise to increase, or counterclockwise to decrease the output power. To get the best performance with the leaset sound distortion, always adjust the output level gain so the meter's level indication does not continuously exceed to the extreme right. CAUTION:It is possible to overdrive the amplifier by setting output level gain too high, which may cause damage or failure. About the internal clip circuitry Special clip circuitry incorporated into your amplifier's design protects the amplifier and speaker system from being damaged from overdriving power. Under normal conditions, the amplifier's clip indicator will flicker as the output power momentarily exceeds the level as set by the output level gain selector. However, under excessive output conditions, the clip indicator lights remain on continuously, altering you that the special clip circuitry has become active. When this occurs, you should simply reduce the output power level by rotating the Master Volume control counterclockwise. Using the A/B Speaker Selector Switch You can listen to speakers on set A or set B individually or simultaneously. CAUTION:If the impedance of your speakers is 4 OHMS, do not use both the speaker A and speaker B terminal at the same time as the net impedance may be low enough to damage your amplifier. Caring for your Pyle Pro Amplifier Your Pyle Pro Amplifier is an example of superior design and craftsmanship. The following suggestions will help you care for your amplifier so you can enjoy years of use: · Keep the amplifier dry. [. . . ] Always start with the volume control set to a LOW level BEFORE you put the headphones on. Connecting to standard AC power After making all other connections, set the POWER switch to OFF position. Mounting the amplifier This amplifier is designed to accept standard rack mounting installations. Two slots on each end of the front panel make it suitable for such an installation. [. . . ]
