Page 8: Rack Installation
Operating instructions Rack installation The EP Series is built for 19” racks. The rack you use should be a ‘double door rack’ where you can open the front and rear panel. When mounting the amplifier into the rack, please make sure that there is enough space around the amplifier. Be careful when mounting the amplifier into the rack. Put the heaviest products into the lower part of the rack. Be aware that fastening the amplifier with four screws on the front panel is not enough. If the racks are being transported or used for mobile use, additionally fasten the products by connecting the rear brackets with the side or ground bars of the rack. In this way, the amplifier cannot be pushed backwards. The front panel is not designed to absorb acceleration forces occuring during transportation. Inputs Short cables runs improve the sound quality remarkably. Input cables should be short and direct, since high frequencies will mostly be absorbed if the cables are unnecessarily long. Besides that a longer cable may lead to humming and noise problems. If the cable runs are unavoidable, you should use balanced cables. Outputs The high damping factor of your amplifier supplies a clear sound reproduction. Unnecessarily long and thin cables will influence the damping factor and thus the low frequencies in a negative way. In order to safeguard good sound quality, the damping factor should lie around 50. The longer a cable has to be the thicker it should be. Connect your speaker systems via the locking speaker connectors or the Bannana/Screw combination (red+, black-) Connection to the mains Connect the amplifier only after having made sure that the correct voltage (240V) is supplied and that the ground cable is earthed. This product falls under Class 1. Do not detach the ground cable. www.prolight.co.uk EPX Series Power Amplifiers User Manual... -
Page 9: Operation
Operating instructions Operation After having connected your amplifier to the mains, turn both gain controls counter clockwise to the “min” position. The last product to be switched on is amplifier. The “ON” and “PROTECT” LED lights up now. If it does not, check if the amplifier is connected to the mains correctly. After the turn on delay the speakers are activated (PROTECT-LED is off). After having set the volume controls of the pre-amplifier to the “OFF” position, turn the gain controls of your amplifier to mid-position. Now adjust the volume with the gain controls CH A and CH B. All important operating modes of the amplifier are arranged on the front panel. -20 dB to 30dB - Output level Clip - Short circuit or impedance too low or signal distorted Protect - Active during stabilisation period after switching on or when one of the protective circuits is activated If you want to switch off the system, switch off the amplifier first in order to avoid acoustic shocks on the speakers.
