# Mobile Studio "Moped" The **mobile studio** is basicly the studio at Speicher XI in a rack *on wheels*. With a stable internet connection and power provieded you can use it to do *radio everywhere.* Be sure to pack additional microfphone, headphones, headphone ambilfiers and a laptop with it. The unit was orginally custom build for the Venice Biennale and other events in summer 2019. ![construction sketch draft (2019)](/files/-McV6jXzglz4cscsXfJO) {% tabs %} {% tab title="Top View" %} ![](/files/-McV8q9tOaBq25ZT1V8J) {% endtab %} {% tab title="Front View" %} ![](/files/-McV94mOzi2wZkkPvqm5) {% endtab %} {% endtabs %} ## Streaming form the mobile unit 1. **Setup** the mobile studio on location 2. Supply **Power** 3. Supply a **wired LAN** connection to the WAN port. The default config requires that the host network (the one you are connecting to) provides a IP-Adress via DHCP and an internet connection without firewall limiations (espacially not on port `8001`). 4. **Turn on** the built-in router, if it is turned off, using the round button labeled "Power". 5. Turn on the mixer on the back. 6. Connection is established if both **PWR**, **LINK** and **LAN** led are glowing in green, on the hardware streamer. 7. Connect your laptop to the on-board **WiFi**. SSID: `Radio Angrezi`, Password: `radioangrezi` 8. Enjoy streaming! 9. Pro Tip: Record on loction using a mobile recorder (e.g. Zoom H4) *The router does allow for many other configurations, including connecting to a host wifi network, instead of using the cable connection.* #### Issues?! Check these things: 1. Is the source on the streaming server available (see below)? 2. Is the internet connection working? Try to use [speedtest.net](http://speedtest.net) and ping `stream.radioangrezi.de` 3. Is port `8001` reachable? 4. Does your input **signal** work and is recieved at the **hardware streamer**? 5. Is the `master source` turned **on**? 6. Is the limiter / compressor **on**? #### Usefull links when using the unit: * configuration for [DEVA hardware streamer ](http://192.168.133.2/)(192.168.133.2), incl. on-board **level meter** * configuration for [on-board router](http://192.168.133.1) (192.168.133.1) * access to [chat / shoutbox](http://talk.radioangrezi.de/studio.html) * server side / client level meter (not great) * connecting / disconnecting the Studio at Speicher XI from the source via [Monit server monitoring](http://studio.radioangrezi.de:2812/darkice) * [studio backend](http://studio.radioangrezi.de/) to check if the master source is **on** or **off.** * [server side recorder](http://studio.radioangrezi.de/controller/) #### Setting up the correct source on the streaming server {% hint style="danger" %} The mobile studio is currently connecting to the *master source* as well:\ **Either the mobile studio or the studio at Speicher XI can connect to the stream source at the same time.** {% endhint %} If you want to **connect the mobile studio** to the stream stop the [darkice service](http://studio.radioangrezi.de:2812/darkice) on the server and plugin in the mobile studio / encoder.\ If you want to **connect the studio** at Speicher XI to the stream, disconnect the mobile studio and reactivate the [darkice service](http://studio.radioangrezi.de:2812/darkice).\ As long as the source is in use, darkice will not start or the mobile studio will fail to connect. ## Equipment on Board * Mixer: A\&H ZED-14 * Limiter/Compressor: Behringer MDX2600 v2 * Streamer: Deva DB91-TX * Router: Asus RT N66U with DD-WRT (Recorder) * 2x SM58 Microphones * 1x Headphones (Audio Technica) * 1x Phone to recieve phone calls + as soundboard * TRS + Chinch Cables for other Devices * LAN cable 3m * TP-Link 5 port switch * Cables, Screwdriver, Tape * printed manuals for hardware on board ## Packing list for Events * N Microphones * N Microphone Cables, e.g. 6 m * N Headphones * N Headphone cables * extra headphone for monitoring (on board) * Headphone amplifier (small rack in the studio) * Snake / Multicore (also in the studio) * cables for laptop or instrument input * LAN cabel, short and long * extra power cabels and distribtion * rain cover * gaffa tape and cable straps * marketing material and angrezi flag * extra mobile recorder (e.g. Zoom H4) for extra local recording ## Configuration (for Tech Crew) {% hint style="info" %} needs to be extended -- JA, 2021 {% endhint %} ### DEVA The harware streamer tryes to stream to two endpoints: * studio.radioangrezi.de:8001 * 10.10.10.63:8001 (if in local network) For both the source `master` and user `source` is used.\ Encoder 1 is cofigured for `MP 3` quality level 4. On TCP port `5000` the live PCM signal can be recieved. This was origianlly indeded to do local recordnings to the flash memory on the Router. ### Router The router is working a Gateway / Router, DHCP-Server, DNS-Sever, Samba-Server, WiFi Access Point, ggf. WiFi Client (as Bridge). The local storage (128 GB) is available from the local network via `local.server.radioangrezi.de` (192.168.133.1). (Name resolution is configured manually with the local dnsmasq.) Sometimes the `NAS` (Samba) settings need to be reapplied to start the server. You can check your the incoming bandwith at the Server (at home) with: `sudo tcptrack -i enp4s0 port 8001` --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
