Galaxy Audio AS-1200T IEM Transmitter

The Galaxy Audio AS-1200T is the working-band budget pick for wireless ears: a half-rack stereo transmitter that ships with rack ears, antenna, and power supply for well under 300 dollars. Small venues and rehearsal rigs use it where a Sennheiser or Shure system per musician is out of reach. Honest entry-tier RF with the essentials done right.

Product overview

Start with the payoff, then work through how it functions, where it fits, and the details that change a real build.

The payoff

IEM Transmitter decisions, organized around the whole rig.

The AS-1200T is Galaxy Audio's answer to a straightforward question: what do you put in the rack when a Sennheiser G4 or Shure PSM300 per musician isn't in the budget? It's a half-rack stereo IEM transmitter occupying half a rack unit, shipping with rack ears, antenna, and power supply already in the box. That matters at the $230 price point — you're not hunting for accessories before the first rehearsal. It fits small venue house rigs, rehearsal setups, and touring situations where one or two secondary performers need ears and the budget is simply fixed.

Function

How it works in the path

Two combo XLR/TRS inputs handle left and right, so you can feed it directly from an aux send on your console without adapters. The front-panel monitor phones output is a practical touch — you can verify what's actually transmitting before the beltpack ever leaves the case. Power draw sits between 10 and 20 watts depending on load, well within what any standard rack power strip handles. At 240mm deep and 2kg, it won't stress a shallow utility rack. What you're getting is entry-tier RF: functional range for smaller stages, honest signal quality, and nothing exotic under the hood.

Best fit

Where it earns its place in the rack

Pick this if you're building a rehearsal room rig, supporting a background vocalist or keyboard player who just needs a basic mix in their ears, or if you're a regional act stretching a tight gear budget. Don't pick it if you're running a dense multi-transmitter festival environment, expecting long throw RF performance, or if the performer is critically dependent on rock-solid dropoutfree reception in an RF-heavy room. In those cases the step up to a dedicated pro-tier system pays for itself fast. But for what it is and what it costs, the AS-1200T does the job without pretending to be something it isn't.

In the rack

Details worth deciding before load-in.

  • Mount it with the front panel accessible — that headphone monitor output is only useful if you can actually plug in and check your mix at line check without pulling anything from the rack.
  • Pair it with a half-rack blank or a second AS-1200T in the same 1U rack slot; the included rack ears are designed for single or mirrored half-rack mounting, so plan your rack panel accordingly.
  • Run the antenna output to an externally mounted antenna positioned clear of metal rack frames and power supplies — the included antenna works, but placement makes a measurable difference in a half-rack budget unit like this.
  • Feed it from a dedicated aux on your console rather than a post-fader send if the mix is going to a performer who needs level independence from FOH — the combo inputs accept both XLR and TRS, so patching is flexible whatever your snake situation looks like.
