OSD Audio 7-Zone Automatic Speaker Selector User Manual

1. Kupu Whakataki me Nekeview

The OSD Audio ATM-7 is a sophisticated 7-zone automatic speaker selector designed to distribute amplified audio signals to various zones within a home or commercial space. It allows users to select between two distinct music sources for each designated zone, providing flexible audio management. This passive device is engineered for seamless integration into existing audio systems, offering remote control capabilities for enhanced convenience.

For optimal performance and to prevent potential damage to your amplifier, it is highly recommended to use impedance matching in-wall volume controls in conjunction with the ATM-7, as this unit does not include built-in impedance protection.

4. Nga korero haumaru

Hei whakarite i te mahi haumaru me te aukati i te kino, me whai i nga whakatupato e whai ake nei:

• Puna Hiko: Whakamahia anake te urutau hiko kua whakaratohia. Me whakarite te voltage ōrite ana ki to tuku hiko rohe.
• Whakahau: Kaua e araia nga whakatuwheratanga hau. Me whakarite kia pai te rere o te hau huri noa i te waahanga kia kore ai e wera rawa.
• makuku: Do not expose the unit to water, moisture, or excessive humidity. Avoid placing liquids near the device.
• Turanga: Whakanohoia te waeine ki runga i te mata papatahi. A ape i te whakanoho kia tata ki nga puna wera, ki te ra tika ranei.
• Ratonga: Kaua e ngana ki te mahi i a koe ake. Tukuna atu nga ratonga katoa ki nga kaimahi whai tohu.
• Whakaōrite impedance: As a passive device, the ATM-7 does not provide impedance protection. Always use impedance matching volume controls or ensure your amplifier can handle the combined speaker load to prevent damage to your ampkaikawe

5. Tatūnga me te Tāuta

Follow these steps to connect your OSD Audio ATM-7 speaker selector:

1. Whakawetohia ngā taputapu katoa: Before making any connections, ensure your amplifier and all audio sources are powered off and unplugged from the wall outlet.
2. Tūhono AmpPutanga whakaahuru: Honoa ngā pūrua putanga o te kaikorero mai i tō amplifier to the "ZONE IN/OUT" terminals on the rear of the ATM-7. The ATM-7 supports two input modes: 2-input (for dual source selection) or 7-input (for individual zone control). Refer to the rear panel diagram for correct wiring.
3. Tūhono Kaikōrero: Connect your speakers to the corresponding "ZONE OUT" terminals on the rear of the ATM-7. Ensure correct polarity (+ to + and - to -) for all connections.
4. Install Impedance Matching Volume Controls (Recommended): For optimal performance and amplifier protection, install impedance matching in-wall volume controls between the ATM-7 and your speakers. This is crucial to maintain a safe impedance load for your amplifier, especially when multiple zones are active.
5. Honoa te Kaiwhiwhi IR: If the ATM-7 unit will be placed out of direct line of sight for the remote control, connect the external IR receiver to the "EXT IR Receiver" port on the rear panel. Position the IR receiver in a location where it can receive signals from the remote.
6. Hono Hono: Plug the provided DC 12V 1.5A power adapter into the "DC 12V 1.5A" input on the rear of the ATM-7, then plug the adapter into a wall outlet.
