User manual PEAVEY UMA 35T II

[. . . ] Cover for UMATM 35TII 1 Intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. Intended to alert the user of the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product. CAUTION: Risk of electrical shock ­ DO NOT OPEN!CAUTION: To reduce the risk of electric shock, do not remove cover. [. . . ] This output is after the EQ and Master Volume Control. LOOP IN/LOOP OUT JACKS (25) Functions as a preamp out/power amp in patch point. The Loop Out signal is a post EQ/Master Volume line level output. LINK SWITCH (26) Breaks the connection between the preamp and the power amp (Loop Out/Loop In). These two jacks are shorted together when the switch is in the "In" position. To use the Loop Out/In jacks as a patch point, the switch must be placed in the "Out" position. The line level output signal is present at the Loop Out jack regardless of switch setting. OUTPUTS (27) A direct output, as well as several isolated transformer outputs, are provided to allow the proper interface between the amplifier and the speaker system. The direct output allows direct connection to a 4 ohm speaker system. To use this output, disconnect the jumper between the 4 ohm terminal and the XFMR terminal. Connect the speaker (or speakers) from the GND terminal to the 4 ohm terminal. Also provided are 8 ohm, 25 volt, and 70 volt balanced outputs. To use these outputs, the jumper between 4 ohm and XFMR must be installed. For 8 ohm speaker systems, connect between the COM terminal and the 8 ohm terminal. For "distributed" speaker systems, 25 volt and 70 volt outputs are provided. One more output is provided on the UMA Series amplifiers. This is a balanced, transformer-isolated line level output. This output is provided for direct connection to booster power amplifiers, etc. This output is designed to deliver 1 V RMS into a 600 ohm load. See Figures 4 through 7 for possible output connections. NOTE: Due to the high gain and frequency response of the UMA Series amplifiers, it is necessary that the input cables be routed away from the output cables to prevent instability. AC OUTLET (UNSWITCHED) (28) Provides AC power for auxiliary equipment with power consumption -- 300 watts maximum. FUSE (29) WARNING: THE FUSE SHOULD ONLY BE REPLACED WHEN THE POWER CORD HAS BEEN DISCONNECTED FROM ITS POWER SOURCE. CAUTION: USING A FUSE LARGER THAN THE RECOMMENDED SIZE COULD RESULT IN PERMANENT DAMAGE TO THE UNIT. The fuse is located within the cap of the fuseholder. If the fuse should fail, IT MUST BE REPLACED WITH THE SAME TYPE AND VALUE IN ORDER TO AVOID DAMAGE TO THE EQUIPMENT AND TO PREVENT VOIDING THE WARRANTY. If the unit repeatedly blows fuses, it should be taken to a qualified service center for repair. LINE CORD (30) (120 V products only) For your safety, we have incorporated a three-wire line (mains) cable with proper grounding facilities. [. . . ] The power supply cord or plug has been damaged. Anything has fallen or been spilled into the unit. The unit has been dropped or the enclosure damaged. The user should not attempt to service this equipment. [. . . ]
