3. Подешавање и инсталација

3.1 Распакивање

Пажљиво уклоните 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 Постављање

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 Везе

Refer to the rear panel diagram for all input and output connections.

• Излази за звучнике: 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): Тхе amplifier features two stereo Bus Inputs (Bus In 1, Bus In 2). These allow a single audio source to be distributed to multiple zones.
• Линијски излази (РЦА): Each zone also has a stereo RCA Line Out, allowing the audio signal from that zone to be passed to another ampлифиер или аудио уређај.
• Улаз/излаз окидача: 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.
• Улаз наизменичне струје: Connect the supplied power cord to the AC IN receptacle and then to a suitable wall outlet.

4.3 Input Selection and Volume Adjustment

On the rear panel, each zone features switches for input selection and rotary controls for volume adjustment:

• Бирач улаза: A slide switch allows you to select the audio input for each zone: Линија у (dedicated input for that zone), Bus In 1, или Bus In 2.
• Контроле јачине звука: Separate rotary controls for Left and Right channels (Vol. Left, Vol. Right) allow for precise volume balancing within each zone.
• Stereo/Bridge Switch: 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

Тхе 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.

5. Одржавање

The OSD Audio MX1680 GEN2 amplifier requires minimal maintenance. Follow these guidelines to ensure optimal performance and longevity:

• Чишћење: Periodically wipe the exterior surfaces with a soft, dry cloth. Do not use liquid cleaners or aerosol sprays, as they may damage the finish or internal components.
• вентилација: Ensure that the ventilation openings on the top and sides of the unit remain clear of dust and obstructions. Dust accumulation can impede airflow and lead to overheating.
• Везе: Occasionally check all cable connections to ensure they are secure and free from corrosion. Loose connections can lead to signal loss or degradation.
• Складиштење: Ако чувате amplifier for an extended period, disconnect it from power and store it in a cool, dry place, away from direct sunlight and extreme temperatures.
