1. Uvod in konecview
The OSD Audio MX1680 GEN2 is a high-performance, multi-channel amplifier designed for distributed audio systems. This Class D amplifier provides 16 channels across 8 independent zones, delivering 80 Watts per channel into 4 Ohms or 50 Watts per channel into 8 Ohms. It is suitable for both residential and commercial audio installations, serving as a main amplifier for multi-room audio or integrating into home theater systems.
Key features include front-panel on/off buttons for each zone, efficient Class D amplification for low distortion, and built-in protection circuitry against thermal overload and short circuits. Its slim, 2U rack-mountable design (hardware included) allows for flexible installation.

2. Varnostne informacije
Pred uporabo te naprave preberite in razumite vsa varnostna navodila. Ta priročnik shranite za poznejšo uporabo.
- vir energije: Povežite amplifier only to the type of power source indicated on the unit. Ensure the voltage je pravilno za vašo regijo.
- Prezračevanje: Ne blokirajte prezračevalnih odprtin. Namestite v skladu z navodili proizvajalca. Okoli enote naj bo dovolj prostora za pravilen pretok zraka.
- Voda in vlaga: Naprave ne izpostavljajte dežju ali vlagi. Na napravo ne postavljajte predmetov, napolnjenih s tekočinami, kot so vaze.
- Toplota: Ne nameščajte v bližini virov toplote, kot so radiatorji, grelniki, peči ali druge naprave (vključno z amplifiers), ki proizvajajo toploto.
- Ozemljitev: This appliance must be grounded. Ensure the power cord is connected to a properly grounded outlet.
- Servisiranje: Tega izdelka ne poskušajte servisirati sami. Vsa servisna dela prepustite usposobljenemu servisnemu osebju.
- Čiščenje: Pred čiščenjem izključite enoto iz električne vtičnice. Za čiščenje uporabite suho krpo.
3. Nastavitev in namestitev
3.1 Razpakiranje
Previdno odstranite 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 Namestitev
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 Povezave
Refer to the rear panel diagram for all input and output connections.
Slika 3.1: Podrobno view of the rear panel input and output connections.
- Izhodi za zvočnike: 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.
- Linijski izhodi (RCA): Each zone also has a stereo RCA Line Out, allowing the audio signal from that zone to be passed to another amplifier ali avdio naprava.
- Vhod/izhod sprožilca: 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.
- Vhod za izmenični tok: Connect the supplied power cord to the AC IN receptacle and then to a suitable wall outlet.

4.2 Nadzor območij
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:
- Izbirnik vhoda: A slide switch allows you to select the audio input for each zone: Vrstica (dedicated input for that zone), Bus In 1, oz Bus In 2.
- Nadzor glasnosti: 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
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.

5. Vzdrževanje
The OSD Audio MX1680 GEN2 amplifier requires minimal maintenance. Follow these guidelines to ensure optimal performance and longevity:
- Čiščenje: 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.
- Prezračevanje: 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.
- Povezave: Occasionally check all cable connections to ensure they are secure and free from corrosion. Loose connections can lead to signal loss or degradation.
- Shranjevanje: Če shranjujete amplifier for an extended period, disconnect it from power and store it in a cool, dry place, away from direct sunlight and extreme temperatures.
