Page 3: Important Remark
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.

Technical Services. Ecler eSAM402 comes with a 3-year warranty. INTRODUCTION The eSAM402 is an easy-to-use professional mixer designed for PA applications. Its main features are: • 3 MIC/LINE STEREO input channels. • 1 fourth STEREO LINE input channel •... -
Page 6: Installation
INSTALLATION The eSAM402 mixer has been specially designed to be installed in a standard 19" rack, taking up 1U. It has been designed to be operated by non-technical users. This is the reason why its tone controls are adjustable only with a screwdriver. On the opposite, input and output level controls use classic and easily accessible rotary knobs. -
Page 7: Inputs
INPUTS The eSAM402 supports two types of audio signals for each of its first three inputs (mono MIC or stereo LINE), selectable by a MIC/LINE switch on the rear panel: Microphone signal: 3 mixing channels offer a Euroblock connector for a nominal input level from –50dBV (3.16mV) to –20dBV (0.1mV), with a GAIN control on the rear panel... -
Page 8: Outputs
OUTPUTS The eSAM402 has a main stereo output (OUT L / OUT R), with electronically balanced Euroblock connectors. Connection is made according to the following diagram: The mixer's main output level (OUTPUT VOL) must be set in order to avoid your system power amp clipping indicators (CLIP) to be permanently lit. -
Page 9: Starting Up
This is directly done via the POWER mains switch. Even is the power-up noise of eSAM402 is minimal, we highly recommend to power up all equipment in the following order: sound sources, mixing units, equalizer, processors and finally power amplifiers. -

the signal entering the mixing amplifier is weak, but even so it contains a background noise, so the signal/noise ratio is low (low signal). When the output amplifier equally amplifies both parts as a whole, the output has a very high background noise. In the second case, as the channel VOL control is set to the maximum, the signal received by the mixing amplifier has a high level and therefore also a high (good) signal/noise ratio, so when this signal reaches the output VOL control and is amplified, the signal/noise... -
