1. Okwu mmalite na gafereview
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.

5. Ntọala na nwụnye
Follow these steps to connect your OSD Audio ATM-7 speaker selector:
- Power Off All Equipment: Before making any connections, ensure your amplifier and all audio sources are powered off and unplugged from the wall outlet.
- Jikọọ AmpMmepụta liifier: Connect the speaker output terminals from your 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.
- Jikọọ ndị ọkà okwu: 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.
- 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.
- Connect IR Receiver: 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.
- Njikọ Ike: 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.
