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. These protections include Dynamic Audio Limiters, Inrush Current Limiter, Short Circuit Protection and Thermal Overload Protection. All PA-Series power amps feature different hi-pass filters with switch selectable cut-off frequency to attenuate unwanted low-frequency signals.

Infinitely variable low-noise high performance fans guarantee absolute thermal stability while keeping fan noise to a minimum. Direct “flow-thru” chassis design allows for a smooth flow of air from front-to-rear, which allows trouble-free operation even in smaller amp-racks.

Compact high density power supply units with low-leakage toroidal transformers provide extensive headroom far above the listed power rating. Premium phoenix style screw-lock connectors prevent accidental disconnection resulting in a more secure connection of audio signal and speaker cables. All PA series “T” version models are equipped with high performance output transformers also provide floating outputs for 50V, 70V and 100V installations. These models also provide voltage limiters to protect the loudspeaker outputs against over-voltage.

Unpacking & Warranty

Carefully open the packaging and take out the power amplifier. Next to the power amplifier itself, the package also includes this owner’s manual, a mains cord, a warranty certificate, four attachable feet as well as screwlock connectors for all inputs and outputs. The warranty period is 36 months starting from the date when receiving the appliance from the dealer. Keep the original invoice, which states the purchase/delivery date together with the warranty certificate at a safe place.

Installation Notes

First of all, please make sure to check that the voltage selector on the amp’s rear is set to the correct position matching the installation site’s local mains voltage.

Generally, installing or mounting power amps should be carried out in a way that guarantees continuously unopposed front-to-rear air circulation. When including an appliance in a closed cabinet or rack shelf system make sure to provide sufficient ventilation. Leave an air duct of at least 2.5“ x 13“ (up to the cabinet’s top ventilation louvers) for air circulation between the rear of the power amplifier and the cabinet’s/rack’s rear wall. Make sure to leave at least 4“ of space above the cabinet or rack shelf system. Since temperatures inside of a cabinet or rack shelf system can easily rise up to 105 degrees during operation, carefully considering the environmental temperature maximum values of all other appliances installed in the same rack shelf system is mandatory (also refer to “Mains Operation & Resulting Temperature”).

When installing the power amp in a cabinet or rack shelf system, make sure to make use of the rear mounting facilities to fix the appliance in place and keep the front panel from bending. If this is not possible, please use mounting-rails instead.

Caution: For problem-free operation do not exceed the environmental temperature maximum of 105 Deg. F.

The power amplifier has to be protected against: moisture (dripping or splashing water), direct sunlight, high temperatures or the direct influence of heat sources, high humidity, extensive dust and vibrations. Condensation on internal parts may occur after transporting the power amplifier from a cold into a warmer environment. In that case operation is only permissible after the appliance has gained the new temp- erature (after approximately one hour). If objects or liquids have intruded the power amp’s enclosure, disconnect the appliance from the mains immediately and contact an authorised service center for inspection before continuing to operate the unit.

Do not use any sprays or solvents for cleaning the appliance, because they might severely damage the surface of the enclosure or lead to dangerous fire hazard.
