Set extender audio ACT AC7710 — digitale/analogico su Cat5e/Cat6 con DAC, TOSLINK I/O, fino a 300 m, alimentato via USB 5V

The ACT AC7710 Audio Extender set transmits digital and analog audio over a single CAT5e/6 cable up to 300 meters. The set includes a transmitter and receiver with TOSLINK optical I/O, a built-in Digital to Analog Converter (DAC) for converting 2‑channel digital audio to analog RCA, and USB 5 V (1 A) power via a wired DC-in jack. The extender supports multiple audio formats and offers bi-directional Power over Cable so only one unit needs an external power source.

Advantages

The AC7710 extends high-quality audio over long distances without multiple cables, with an integrated DAC for straightforward digital-to-analog conversion. Bi-directional Power over Cable simplifies installation by allowing either the transmitter or receiver to be powered while the other unit draws power through the CAT cable. The unit supports common surround and stereo formats and includes mounting brackets for fixed installations.

Suitable for

When it may not be suitable

The extender is not intended as a network audio device; it transmits point-to-point audio over CAT5e/6 and does not provide network streaming or switching functions. Very high-resolution multi-channel formats beyond the supported sample rates or proprietary multi-channel formats may not be passed through depending on the selected application mode.

Key specifications

How to use

Connect the transmitter to the audio source using the appropriate input (TOSLINK for digital or RCA for analog). Connect the receiver to the destination device using RCA or TOSLINK as required by your setup. Link transmitter and receiver with a single CAT5e/6 cable sized to the required distance. Power either the transmitter or the receiver from the 5 V USB supply; the other unit will receive power via the CAT cable (PoC). Select the matching application mode: digital-in to digital+analog out, multi-channel digital passthrough to SPDIF, or analog RCA-to-RCA pass-through.

What to consider before purchase

Recommendations

For longest reliable runs, use shielded or high-quality CAT6 cable and keep the sample rate at 48 kHz when approaching the maximum 300 m distance. Confirm the chosen application mode matches your source and receiver capabilities to ensure correct format conversion and pass-through.
