  • Page 4: Important Note

    There are no user serviceable parts inside the amplifier. 2. INTRODUCTION With the PAM amplification series, ECLER introduced in early 90's a new concept to the world of professional audio: The use of switching field effect transistors. The integration of these parts for audio applications represents a firm and spectacular enhancement comparing to conventional amplifiers.

    3.3. Signal input connections NPA Series rear panel has analog and digital inputs. Input selection is performed from the front panel menu or from EclerNet Manager control software. Please refer to the EclerNet Manager software manual for more information. • Analog inputs: The signal input connectors are of XLR-3 type (19), electronically balanced.

  • Page 7: Operation And Usage

    4. OPERATION AND USAGE 4.1. Start up If the POWER (17) switch is operated on the rear panel, the amplifier receives mains power and can be turned on locally or remotely (see Control panel section). In a complete audio installation, it is important to start up the equipment in the following sequence: sound sources, mixer, equalizers, active filters and finally power amplifiers.

  • Page 8: Front Panel Handling

    4.3. Front panel handling The front panel includes a series of controls and indicators: Backlit LCD display for displaying menus, settings and amplifier parameters. On / Off key (POWER ON). Menu navigation keys (MENU / PREVIOUS / NEXT). Rotary/push controls for adjusting parameters (CHANNEL 1 / CHANNEL 2). LED indicators (see section 4.2).
  • Page 9 • Activate / deactivate a channel muting (by pressing and holding the CHANNEL 1 or CHANNEL 2 rotary knob): A label with the text "MUTE" is displayed when this feature is activated. • Show text labels assigned to the unit and to its amplification channels (by clicking on the TAG button): This window, named TAGS, disappears after a short time, and the main window returns.
  • Page 10 All other amplifier functions and settings are accessed through the menu structure as described in the following diagram:...
  • Page 11 • MONITOR menu VU-meters monitoring scale selection: Output power (Watts), RMS or peak. Output voltage (Volts), peak or RMS. Input signal voltage, RMS. Display through dedicated screens: Load impedance, in ohms. Temperature, in % of the alarm triggering temperature. AC power supply voltage. Cumulative operating time of the amplifier, in hours: minutes.
