Amplifier Inter-M PM-260

The Inter-M PM-260 is a multifunctional mixer-amplifier delivering 600W of power. At its core is a modern Class-D amplification circuit, which guarantees high efficiency, low heat dissipation, and minimal power consumption, critical for reliable commercial installations.

The device offers exceptional connection flexibility. It is equipped with three balanced universal inputs (mic/line) with switchable +24V phantom power, two additional balanced line inputs, and one unbalanced stereo input. The latter is thoughtfully designed with 2xRCA connectors on the rear panel and a convenient 3.5mm mini-jack on the front, ideal for quickly connecting laptops or mobile devices.

The amplifier is optimized for use in public address (PA) systems. It features built-in "Siren" and "Chime" signals, which can be activated by buttons on the panel or via external dry contacts. A dedicated "Tel In" emergency input has the highest priority and automatically mutes all other audio sources during emergency announcements. The depth of this muting can be precisely adjusted.

A key feature of the PM-260 is its ability to work with various types of speaker systems. It supports both low-impedance (4/8 Ohm) and high-impedance (70V/100V) distributed lines. For high-voltage lines, there is a built-in 5-zone selector, allowing for easy audio distribution across different areas. Functionality can be expanded by connecting an RM-05 microphone station for convenient zone paging.

For standalone operation, the device includes a built-in media player with a front-panel USB port, supporting playback of MP3, WAV, and WMA files. A two-band equalizer (Bass/Treble) is provided for fine-tuning the overall sound. Visual monitoring is ensured by a comprehensive indication system, including a 7-segment output level indicator, input signal indicators, protection status, and active zone selection.
