3. Kurulum ve Kurulum
3.1 Paketin açılması
Dikkatlice çıkarın amplifier from its packaging. Verify that all components listed in the 'What's in the Box' section are present. This includes the MX1680 GEN2 amplifier and the Quick Start Guide.
3.2 Yerleştirme
The MX1680 GEN2 is designed for rack mounting (2U height) or placement on a flat, stable surface. Ensure adequate ventilation around the unit to prevent overheating. Avoid placing it near other heat-generating equipment.
3.3 Bağlantılar
Refer to the rear panel diagram for all input and output connections.
Resim 3.1: Ayrıntılı view of the rear panel input and output connections.
- Hoparlör Çıkışları: Connect your speakers to the corresponding zone terminals. Ensure correct polarity (+ to + and - to -). The amplifier supports both 4-ohm and 8-ohm speakers. For bridged mode operation, refer to section 4.3.
- Line Inputs (RCA): Each zone has a dedicated stereo RCA Line In. Connect your audio sources (e.g., pre-amplifier, media player) to these inputs.
- Bus Inputs (RCA): The amplifier features two stereo Bus Inputs (Bus In 1, Bus In 2). These allow a single audio source to be distributed to multiple zones.
- Hat Çıkışları (RCA): Each zone also has a stereo RCA Line Out, allowing the audio signal from that zone to be passed to another amplifier veya ses cihazı.
- Tetikleyici Giriş/Çıkış: The 12V Trigger In allows the amplifier to be turned on/off by an external device. The 12V Trigger Out can be used to control other devices.
- AC Güç Girişi: Connect the supplied power cord to the AC IN receptacle and then to a suitable wall outlet.

4. Kullanım Talimatları
4.1 Güç Açma/Kapatma
Press the main power button on the front panel to turn the amplifier on or off. A red LED indicator will illuminate when the unit is powered on.

4.2 Bölge Kontrolü
Each of the 8 zones has a dedicated button on the front panel. Pressing a zone button will activate or deactivate that specific audio zone. The corresponding LED will indicate the zone's status.
Image 4.2: Front panel zone selection buttons.
4.3 Input Selection and Volume Adjustment
On the rear panel, each zone features switches for input selection and rotary controls for volume adjustment:
- Giriş Seçici: A slide switch allows you to select the audio input for each zone: Satır içi (dedicated input for that zone), Bus In 1, veya Bus In 2.
- Ses Kontrolleri: Separate rotary controls for Left and Right channels (Vol. Left, Vol. Right) allow for precise volume balancing within each zone.
- Stereo/Köprü Anahtarı: A switch allows you to configure the zone for stereo operation or bridged mono operation. In bridged mode, two amplifier channels combine to deliver higher power to a single speaker. Ensure the speaker impedance is appropriate for bridged mode (typically 8 ohms minimum).
4.4 Audio Sensing
The amplifier incorporates an audio sense feature that automatically activates a zone when an input signal is detected and turns it off after a period of no signal. This helps conserve power and prolong the unit's lifespan.
