Graphic Symbol Explanation 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.
Always use shielded cables to make the connections between devices. 2. INTRODUCTION The Ecler Essentials eGPA amplifier series offers the renowned professional reliability of Ecler amplifiers at an affordable price. It consists of 4 models: with a power of 2 x 150W RMS @ 4Ω (eGPA2- 150), 4 x 150W RMS @ 4Ω...
3. INSTALLATION 3.1. Placement, mounting, cooling All eGPA amplifier models are presented in standard 19” rack format and are 1 unit high. It is important that the amplifier, as a heat source, is not placed next to other equipment nor exposed to high temperatures.
3.5. Limiter circuit This is an extra protection always enabled in the eGPA series amplifiers. This circuit dynamically limits the input signal to avoid clipping of loud signals at the amplifier output; it automatically reduces the input level not to exceed approximately 5% distortion.
4.3. Indicators eGPA amplifiers include a simple yet effective indication system. PROT/STBY indicators (7) show the absence of loudspeaker output signal. These indicators may light up for following reasons: 1. During start-up, until the STANDBY time has passed. This time period is needed for the internal operating voltages to settle.
