Considerations; Starting Up; Mono/Stereo Modes And Inputs-Outputs Assignment; Equalization - Ecler eSAM603 Notice D'utilisation

6. CONSIDERATIONS

6.1. Starting up

This is directly done via the POWER mains switch. Even is the power-up noise of eSAM603 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 power down sequence is the inverse of the
power up one.

6.2. MONO/STEREO modes and INPUTS-OUTPUTS assignment

On the front panel, each input channel has a master level control (VOL) and 3 buttons (A, B and
C) to assign its signal to one or more outputs of the unit. When one of these buttons is engaged, the
signal is sent to the corresponding output.
Microphone inputs are always mono, so you can send the mono signal at the A, B and/or C
destination output by pressing the corresponding button. Example for input 1:
Input (type)
IN1 (microphone, mono)
For line level signals, the output assignment depends whether these signals are in MONO or
STEREO mode (MONO/STEREO switch on the rear panel for each MIC/LINE or LINE input). Example:
Input (type)
IN2 (LINE, switch in the STEREO
position)
IN3 (LINE, switch in the MONO
position)
The C output is always mono and therefore always receives a mono sum of L + R line inputs that
have been assigned to this output, regardless of their MONO/STEREO setting.
Additionally, the STEREO/SINGLE front panel switch allows you to choose between two ways to
control the A and B output volume:
 simultaneously and only with OUT A control, OUT B control being disabled (switch in the
STEREO position). This mode is suitable for the sound reinforcement of a stereo zone (A, left
channel / B, right channel) and a mono zone (C)
 independently, using the A and B controls (switch in the SINGLE position). This mode is suitable
for the sound reinforcement of three zones, A, B and C

6.3. Equalization

The tone controls of the A/B and C outputs provide a ± 15dB gain/attenuation for each of the
three available bands, and their central operating frequencies are 100Hz, 2kHz and 10kHz.
