3. Tatūnga me te Tāuta
3.1 Te Wetewete
Tango tupato te 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 Whakanoho
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 Hononga
Refer to the rear panel diagram for all input and output connections.

Whakaahua 3.1: Taipitopito view of the rear panel input and output connections.
- Putanga Tukuoro: 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): Ko te amplifier features two stereo Bus Inputs (Bus In 1, Bus In 2). These allow a single audio source to be distributed to multiple zones.
- Nga Putanga Raina (RCA): Each zone also has a stereo RCA Line Out, allowing the audio signal from that zone to be passed to another amphe taputapu ororongo ranei.
- Keu ki roto/waho: 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.
- Whakauru Hiko AC: Connect the supplied power cord to the AC IN receptacle and then to a suitable wall outlet.

4. Nga Tohutohu Whakahaere
4.1 Hiko / Whakaweto
Pēhia te pātene mana matua i te papa o mua hei huri i te amplifier on or off. A red LED indicator will illuminate when the unit is powered on.

4.2 Mana Rohe
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:
- Kaitoha Whakauru: A slide switch allows you to select the audio input for each zone: Raina ki roto (dedicated input for that zone), Bus In 1, ranei Bus In 2.
- Mana Rōrahi: 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
Ko te 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. Tiaki
The OSD Audio MX1680 GEN2 amplifier requires minimal maintenance. Follow these guidelines to ensure optimal performance and longevity:
- Te horoi: 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.
- Whakahau: 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.
- Hononga: Occasionally check all cable connections to ensure they are secure and free from corrosion. Loose connections can lead to signal loss or degradation.
- Rokiroki: Mena kei te penapena te ampte pūhiko mō te wā roa, momotuhia te hiko ka rongoa ki te wāhi hauhautanga, maroke, kia matara atu i te rā tika me ngā pāmahana tino kino.
