The T-7701 features two AC power outlets on the rear panel that are switched on/off based on network activity. When an audio stream is received, the outlets are energized to power connected amplifiers. After a configurable idle timeout (5-60 minutes), the outlets are switched off to save energy. Maximum total load: 5A (resistive).
The T-7701 is a 1U rack-mount IP network audio decoder designed to bridge traditional analog audio equipment with modern IP-based broadcasting systems. It receives streaming audio from the T-7700 series server and outputs high-quality line-level analog audio for connection to external amplifiers, mixing consoles, or recording devices.
Intelligent Power Control: One of the standout features of the T-7701 is its two built-in switched power outlets. These outlets automatically power connected amplifiers only when audio is being played, then shut down after a programmable idle period. This significantly reduces energy consumption in 24/7 installations such as schools, retail stores, and corporate offices.
Local Media Playback: The front-panel USB port allows direct playback of MP3/WAV files from a USB drive. This enables local announcement playback, background music, or emergency messages even if the network server is unavailable. Playback is controlled via the front panel buttons or included infrared remote.
Flexible Inputs & Priority: MIC and AUX inputs allow local audio sources to be mixed with network streams. The EMC (Emergency) input has highest priority, automatically muting all other sources when activated – essential for fire alarm integration and emergency paging.
Two rear-panel AC outlets switch automatically with audio activity. Saves energy, reduces heat, and extends amplifier life.
Full-function IR remote included. Volume, source selection, USB track control, and treble/bass adjustment from across the room.
Emergency input forces highest priority, interrupting all other audio. Direct interface with fire alarm systems.
RJ11 interface for connecting T-7771 wall-mounted volume control panels. Adjust volume from remote locations.

The RJ11 interface supports connection of up to 3 T-7771 wall-mounted volume control panels in parallel. Each panel provides capacitive touch volume up/down and status LED. Maximum cable length: 15 meters. Volume range: 0-100%, stored per source.
| Model | Form Factor | Outputs | Power Control | Special Features | Best For |
|---|---|---|---|---|---|
| T-7701 | 1U Rack | 1x LINE | 2x AC outlets | USB, IR, 3-wire volume | Analog amp integration |
| T-7701Z | 1U Rack | 8x 100V zones | 1x AC outlet | 8-zone matrix | Multi-zone paging |
| T-7704 | 1U Rack | 4x LINE | 4x AC outlets | 4 independent channels | Multi-source distribution |
The switched AC outlets are designed for amplifiers only. Do not connect inductive loads (motors, transformers) exceeding 0.5A. Maximum total current: 5A (resistive). For installations with multiple high-power amplifiers, use the T-7701 outlets to trigger a separate contactor or power sequencer.
The T-7701 supports field firmware updates via RS-232 or network TFTP. New codecs, priority schemes, and power management features can be added post-installation. Contact ITC support for latest firmware versions.
