Page 3: Important Safety Instructions
IMPORTANT SAFETY INSTRUCTIONS The lightning flash with arrowhead symbol, within an equilateral triangle is 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. -
Page 4: Description
DESCRIPTION Congratulations on your ElectroVoice PA series power amplifier purchase! The ElectroVoice PA-Series power amp line combines outstanding audio performance, exceptional reliability and secure operational safety in a compact 2RU chassis design. All models in the PA Series provide several protection circuits which not only prevent the power amplifier itself but also the connected loudspeaker systems from being damaged. -

FRONT PANEL Mains Switch Use the mains switch to switch the unit’s power on. A soft-start function prevents inrush current peaks on the mains, additionally preventing the mains line protection switch from activating during the amp’s power-on operation. Loudspeaker outputs are activated via relay switching with a delay of approx. -
Page 6: Rear Panel
REAR PANEL Audio Signal Inputs The electronically balanced inputs facilitate the connection of external signal sources (e.g. mixing consoles). When screwed to the power amp, the screwlock connectors provided with the unit prevent accidental disconnection. Choosing balanced cables (2 conductors for audio signals + separate shielding mesh) for LF-signal connection is generally recommended, even when the connected signal source does not provide balanced output signals. -
Page 7: Loudspeaker Outputs
Bridged Mode the minimal impedance is 8 ohms and that the input audio signal has to be fed to channel A (or C). PA1250T, PA2250T & PA2400T Integrated audio output transformers convert the power amp’s nominal output voltage to 50V, 70V and 100V. -
Page 8: Mains Fuse
REAR PANEL Mains Fuse Under normal circumstance, the mains fuse blows only in the event of failure. When replacing the fuse, make sure to use a fuse of the same type with identical amperage, voltage and blow characteristics. If the mains fuse blows repeatedly, please contact an authorized service centre. - Page 9 MAINS OPERATION & RESULTING TEMPERATURE Mains Operation The following tables provide a useful aid in determining power supply and cabling requirements. Column “1/8 max. output power into 4 ohms ” states the values to be used for normal operation. These results were measured with the power amplifier being operated at maximum output and a Pink Noise signal according to EN60065 applied at the input, which approximately represents the strain of an audio signal driving the power amp at maximum modulation.
