Page 3: Important Remark
1. IMPORTANT REMARK 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. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. - Page 4 9. Do not defeat the safety purpose of the polarized or grounding type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety.

Page 5: Important Note
4. INTRODUCTION The Ecler Essentials eHSA amplifier series offers the renowned professional reliability of Ecler amplifiers at an affordable price. It consists of 2 models: one with a power of 2 x 150W RMS @ 70/100V, high impedance (eHSA2-150) and a second one with a power of 4 x 150W RMS 70/100V, high impedance (eHSA4- 150). -
Page 6: Installation
5. INSTALLATION 5.1 Placement, mounting, cooling All eHSA amplifiers 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. The built-in convection cooling requires at least one free rack unit CAUTION: (empty space) both above and below each amplifier to ensure a correct air flow. -
Page 7: Power Saving Mode
5.5 Limiter circuit This is an extra protection always enabled in the eHSA 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. -
Page 8: Input Attenuators
6.2 Input attenuators This consists of rotating potentiometers, situated on the front panel (5, 6). These attenuators allow connecting the amplifier to different types of mixers and processors, independent level control and connection of speakers that can't handle the wattage supplied by the output stage at full power, without risking damage if the volume of the preamplifier-mixer is set too high. -
