## Overview

The OSD Audio SRT4 GEN2 is a professional-grade 4-zone media streamer delivering 24-bit audiophile sound with independent DACs per zone. Controlled via a sleek iOS/Android app, it supports major streaming services and versatile inputs including RCA, digital coax, optical, and USB. Designed for seamless multi-room audio in homes or commercial spaces, it features 12V trigger outputs and RS485 connectivity for smart amplifier control and system expansion.

## Description

The SRT4 is a 4-zone Multimedia Audio Streaming Server that has you covered for both commercial and residential clients who want to stream and control audio in homes, restaurants, offices, gyms, or retail spaces without making the penny pinchers flinch. This feature-rich wireless streaming pre-amplifier connects and delivers 24-bit audiophile-level sound quality from a music library, Spotify, Napster, iTunes or iHeartRadio and can be used with Alexa to play other music sources or internet radio—all easily controlled with the free OSD Play App for smartphones or tablets.Great Sound – EverywhereDistributed audio has gone through a renaissance over the last few years thanks to Bluetooth and now the more sophisticated Wi-Fi options. Customers can enjoy tunes from the kitchen to the garage or play internet radio in the conference room and mellow jazz in the waiting room. The downside of streaming is the sound quality, which is generally compressed by the tiny Digital-to-Analog Converters or DACs in smart phones and tablets. The SRT4 bypasses the DAC and uses its own (one for each zone), more robust converter to deliver a 24-bit audio signal (CD/DVD quality) to external amplifier sand speakers. The higher bit rate and uncompressed signal reveal sonic subtleties that make a great song sound even greater.Advanced Inputs and Outputs/ RS485 ConnectivityThe app driven SRT4 Multimedia Audio Streaming Server includes advanced connection capabilities with three key sources including Built in Wi-Fi, external USB input both per zone and a universal bus featuring two Stereo RCA inputs as well as a single Digital Fiber optic input. These three Bus Inputs can be selected independently per zone through the App Line outs include RCA stereo and digital optical inputs per Zone. There are two options for setting up the Wi-Fi connection. The first is a Lan (RJ45) for direct connection where all four Wi-Fi links configure automatically to a Wi-Fi router. The second option is a wireless connection using a WPS button included for each zone. Each Wi-Fi link needs to be set individually for each of the four zones. Lastly there is a RS485 (similar to RS232 but for controlling multiple devices) connector for interfacing with an external control system.Adding additional SRT4s / App-Driven SimplicityPair our SRT4 with additional SRT4 Streaming Four Zone Servers for those bigger applications where four zones is not enough. All zones can be controlled by the Free OSD Audio Player App to stream music to other audio zones directly through your phone or tablet. The streaming possibilities (and zones) are endless! Through the app you can group any number of zones. Any combination can be selected trough the app, even all zones at once. Imagine showing this to clients who will think you are a genius!

Review: I like that I can use this without depending on my phone for my music source. desertcart music and iheart radio are ok, Spotify is hit and miss but I would like to be able to use pandora or my Sirius soon.
Review: I bought the 4 source version to run with my OSD Max12 Whole Home Amplifier and the pair work great together. However, I took off 1 star because pandora wasn’t there, and the app would not work over in-bound vpn even though the other OSD app does work on inbound vpn. The OSD Player apps wants you to be on WiFi but when you vpn into your home from Wiregard app don’t use WiFi. The OSD Max12 app doesn’t care about WiFi so it just works. You do need to have accounts in the streamers apps. I created desertcart, Tidal, Spotify, and Tune-In accounts. I can stream Pandora (anything else over Airplay) which works fine. However, when you stream over you phone it limits what you can do with the phone and runs down battery. You can created favorites and presets. I still don’t understand the “inputs” on each of the 4 Zones, but I did figure out the global inputs. I could not get that working yet but fortunately I have needed to use that part of the streamer as the “outputs” are the main use case for me.

*by J***. on 24 March 2021*

The Streaming Server works great however it's a pain to fully integrate, as they have no documentation. They list RS-485 control as a feature but have yet to post the documentation of supported commands. They also need to have a documentation of network ports used yet, there is none, Sonos provides this right on there website: https://support.sonos.com/s/article/688?language=en_US . I also contacted Support 4 times about information on any of these and all I got back was the auto response and crickets each time. Could be great I like the form factor better than using a bunch of Sonos Ports. Currently using these to get 12v Trigger output from each zone but Obviously that gets expensive: https://www.amazon.com/gp/product/B07QS89MZG/ The Features Missing (Besides documentation, which I plan on posting to the OSDAudio Subreddit once I figure out). - 12 Triggers, This really should have 12v trigger outputs 1 per Zone as well as one main out that turns on any time any zone is active. - Input Sharing, like the Sonos Port does the input should be available over the network to any device as a source but it's only available to the local zones to the device, so if you have more than one STR4 you will need to connect it to both.
