Receivers, Speakers, and Playback Devices for Glaiden's Audio
The 
Radio Receiver is the entry point for hearing broadcasts in Glaiden's Audio, and it is also the cheapest device to build: an 
Antenna, four 
Iron Ingot, one 
Circuit Board, and one 
Speaker in a shaped recipe. Everything else in the listening chain is an upgrade or a sidegrade to that one block, so it pays to know what each device does before you spend diamonds on a 
High Quality Radio Receiver.
The basic listening chain
A broadcast only reaches you if something on your end can pick it up. The Radio Receiver is that something. It combines three roles in a single block: the Antenna handles reception, the Circuit Board handles the signal processing, and the Speaker turns the result into audible sound. You need one of each, plus four Iron Ingot for the chassis, arranged as a shaped recipe.
Because the recipe is shaped, ingredient placement matters — you cannot scatter the parts into a crafting grid and hope. Keep the Antenna and Speaker where the recipe expects them and fill the body with Iron Ingot.
Upgrading to high quality
The High Quality Radio Receiver is not a separate machine you build from scratch. It is a direct upgrade of an existing Radio Receiver: surround one Radio Receiver with four 
Diamond in a shaped recipe and you get the high quality version back.
That makes the upgrade path unusually clean. Build the cheap Radio Receiver first, confirm your Antenna placement is actually pulling in a signal, and only then commit the diamonds. If you craft the High Quality Radio Receiver before you have a working reception setup, you have spent four Diamond to debug the same problem you could have debugged for free.
Speakers and how they differ
The Speaker is the component that makes sound possible at all. It appears in every listening recipe in the mod, which tells you something important: there is no way to hear a broadcast without one. If you are short on Speaker, you are short on every device on this page.
Two devices exist specifically to push sound outward rather than into your own ears:
- The
Boombox takes six Iron Ingot, two Speaker, and one Circuit Board. The doubled Speaker count is the giveaway that this is a louder, wider-coverage option than a plain receiver. - The
Loudspeaker takes seven Iron Ingot, one Speaker, and one Circuit Board. It trades the Boombox's second Speaker for an extra Iron Ingot, making it the heavier build of the two.
Both are shaped recipes, and both need a Circuit Board, so plan your circuit production around the fact that every device here consumes one.
Redstone Dynamic
The 
Redstone Dynamic is the odd one out. Its recipe is four Iron Ingot, four 
Redstone Dust, and one Speaker — no Circuit Board and no Antenna at all.
That absence is the useful detail. Where the Radio Receiver, Boombox, and Loudspeaker all route through a Circuit Board and depend on an Antenna for reception, the Redstone Dynamic is built purely from metal, redstone, and a Speaker. If you are working without a Circuit Board supply, or you have not yet crafted an Antenna, this is the device you can still build.
Planning your materials
Reading the recipes together gives you a shopping list rather than five separate puzzles.
Iron Ingot is the backbone. The Radio Receiver wants four, the Boombox six, the Loudspeaker seven, and the Redstone Dynamic four. If you intend to build one of each, that is twenty-one Iron Ingot before you have touched anything else.
Speaker is the second constraint. The Radio Receiver, Loudspeaker, and Redstone Dynamic each need one, and the Boombox needs two — six Speaker for a full set.
Circuit Board is needed by the Radio Receiver, Boombox, and Loudspeaker, but not by the Redstone Dynamic. Three Circuit Board covers those three devices.
Antenna appears exactly once, in the Radio Receiver. Since the High Quality Radio Receiver is crafted from a finished Radio Receiver rather than from raw parts, you never need a second Antenna for the upgrade.
Diamond appears only in the High Quality Radio Receiver, at four per upgrade.
Redstone Dust appears only in the Redstone Dynamic, at four per craft.
Choosing what to build
If you want one device and nothing else, build the Radio Receiver. It is the least expensive way to hear a broadcast and it is the prerequisite for the High Quality Radio Receiver, so nothing you spend on it is wasted.
If you already have a Radio Receiver and diamonds to spare, the High Quality Radio Receiver is a straight conversion of a block you own.
If you want sound projected to an area rather than to yourself, choose between the Boombox and the Loudspeaker. The Boombox costs one more Speaker; the Loudspeaker costs one more Iron Ingot. Pick based on which of those two materials you have in surplus.
If you are locked out of Circuit Board production, the Redstone Dynamic is your only option on this list, and it needs nothing but Iron Ingot, Redstone Dust, and a Speaker.
