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.

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.
IMPORTANT NOTE Thank you for choosing our Ecler eHMA mixing amplifier! VERY IMPORTANT It is to carefully read this manual and to fully understand its contents before any connection in order to maximize your use and get the best performance from this equipment.
INSTALLATION eHMA series powered mixers are specially designed to be installed in a standard 19" rack, taking up 1U or 2U (eHMA60 is a half-width unit, and optional accessories are available for standard rack mounting). It has been designed to be operated by non-technical users.
INPUTS The eHMA inputs support two types of audio signals (mono microphone MIC or stereo LINE). Dual inputs have a MIC/LINE selector located on the rear panel: • Microphone signal: Euroblock connector for a nominal input level from –50dBV (3.16mV) to –20dBV (0.1mV), with a GAIN control on the rear panel to adjust the gain.
OUTPUTS The eHMA offers the following powered outputs: • 1 low impedance mono output: all models. eHMA250 also has 250W @ 8Ω output • 1 mono 70/100V line (high impedance) output: eHMA60 • 2 mono 70/100V line (high impedance) zone outputs (Z1 and Z2), with switches on the front panel to enable or disable the speaker line connected to each of them): eHMA120 •...
Other connections on the back panel: • AUX/REC output (not available for eHMA60) with a nominal output of 0dBV (10kΩ load). • MUTE remote-control input: to connect an external dry contact closure. It allows connection of fire detection systems and other safety devices that have to mute the mixer by using this control signal.
8.2. Equalization The tone controls of the main output provide a ± 15dB gain/attenuation for each of the bands, and their central operating frequencies are 100Hz and 10kHz. 8.3. Ground loops, background noise You should always make sure that the signal sources coming to the mixer, as well as all devices connected to its outputs, do not have their grounds interconnected, that is;...
