AuraSonics STAGE 200 — an affordable digital wireless system with handheld and bodypack transmitters

Grigory Liadov

Our readers know AuraSonics from our review of its powered monitors, the AuraSonics KN4. The brand belongs to one of Russia's largest professional audio distributors, Audioproject. The AuraSonics product range is growing. In early 2024, it gained the new STAGE 200 wireless series.

The new series is interesting mainly because it is an affordable digital wireless system. Its price is comparable to inexpensive analog systems using FM modulation. AuraSonics STAGE 200 systems use interference-resistant 4DQPSK modulation in the 660–690 MHz UHF band. The stated range reaches 80 meters with line of sight when the transmitters are set to high output power. The series includes several components that can be bought in packages or separately, allowing users to build the configuration they need.

The AuraSonics STAGE 200 series includes the STAGE 200DHT handheld transmitter, STAGE 200DBT bodypack transmitter, and two receivers: the single-channel STAGE 201DR and two-channel STAGE 202DR. We will cover all these devices, starting with the two-channel receiver.

AuraSonics STAGE 202DR

The receiver's large display clearly shows the selected channel, current frequency, and other operating parameters. There are no complex settings, and operation is fairly simple.

The central SET button moves between adjustable parameters, and the arrow buttons change their values. The receiver has 299 fixed-frequency channels in 100 kHz steps within its operating band. A specific frequency channel can be chosen manually, but scanning the radio environment is better. The receiver finds the nearest free frequency, after which the settings can be sent to the transmitter. All necessary transmitter settings synchronize through the usual IR port. Once synchronization is complete, the system is ready to use. Other useful functions include automatic setting lock, transmitter battery status display, and two transmitter power modes.

The receiver has a small plastic housing that fits easily into a workspace. For fixed installations, rack mounting is possible with the optional AuraSonics STAGE RM1 brackets. These also allow the antennas to move to the front. The receiver's antennas are removable and can be connected at the front through special extension cables.

According to the manufacturer, STAGE 200 receivers use two-antenna diversity reception. The receiver automatically selects the antenna with the stronger signal, improving interference resistance and connection stability.

Balanced XLR outputs connect to a mixer or loudspeakers and carry each channel separately. The 1/4-inch TRS line output carries a mix of both channels.

AuraSonics STAGE 201DR

The single-channel STAGE 201DR looks almost the same as the two-channel STAGE 202DR. The main differences are analog volume control and a slightly different channel structure. The STAGE 201DR range is also divided into 299 fixed-frequency channels in 100 kHz steps, with frequencies arranged in 10 groups of 20 channels. Controls and operating modes otherwise match the two-channel receiver.

AuraSonics STAGE 201DR receiver specifications

Number of channels	One
Signal modulation	4DQPSK
Frequency stabilization	Crystal-controlled digital tuner with PLL
Operating frequency range	660–690 MHz, 299 channels (10 groups of 20 channels)
Frequency response	30 Hz–20 kHz ±2 dB
Dynamic range	>96 dB
Total harmonic distortion	<0,3%
Output level	400 mV, analog level control
Signal-to-noise ratio	>96 dB
Image rejection	>80 dB
Sensitivity	-95 dB
Power supply	12 V, 500 mA

Although it is a single-channel receiver, it has two antennas. The STAGE 201DR also uses diversity reception to improve system stability. Rack mounting is available too.

Connections include balanced XLR and unbalanced TRS outputs.

AuraSonics STAGE 200DBT

The AuraSonics STAGE 200DHT handheld transmitter is a familiar full-size microphone. It looks neat and compact compared with many competing handheld units. Its plastic housing keeps weight down. The plastic is thick and rigid, unlike the thin, resonant housings of very cheap Chinese models that amplify every handling sound. The evenly distributed weight makes the transmitter comfortable to hold. It does not feel top-heavy or tend to slip. Beveled edges near the bottom stop the microphone from rolling on a flat surface.

The microphone has a small LCD and a power button. The display shows the selected channel and remaining battery charge. A short press selects Mute. Hold the button for 2 seconds to switch the microphone off completely.

Handheld transmitter specifications AuraSonics STAGE 200DBT

Capsule	Dynamic
Polar pattern	Cardioid
RF output power	3 mW/10 mW
Operating frequency range	660–690 MHz
Display and indicators	LCD display
Signal modulation	4DQPSK
Receiver pairing	IR port
Range	Up to 80 meters with line of sight
Housing material	Plastic
Operating time	Up to 5 hours
Power supply	2 × 1.5 V AA batteries

The transmitter uses a conventional dynamic capsule with a cardioid polar pattern. A rubberized base isolates it from housing vibration. Foam protects the front of the diaphragm. Another foam layer under the metal grille provides extra breath protection.

The transmitter works with both STAGE 200 receivers. Synchronization uses an IR port in the battery compartment. Two AA batteries provide up to 5 hours of continuous operation, according to the specification.

AuraSonics STAGE 200DHT

Like the handheld microphone, the AuraSonics STAGE 200DHT bodypack transmitter works with both STAGE receivers. The bodypack transmits an electret microphone signal and comes with a headset microphone.

The transmitter has a conventional compact bodypack design. Its light plastic housing has a belt clip. The LCD shows channel, frequency, and battery charge. Two AA batteries provide up to 5 hours of continuous use. The IR port for receiver synchronization is under the battery-compartment cover.

Bodypack transmitter specifications AuraSonics STAGE 200DHT

Signal modulation	4DQPSK
RF output power	3 mW/10 mW
Operating frequency range	660–690 MHz
Display and indicators	LCD display
Receiver pairing	IR port
Range	Up to 80 meters with line of sight
Housing material	Plastic
Operating time	Up to 5 hours
Power supply	2 × 1.5 V AA batteries

All controls are on top: a microphone sensitivity control and a three-position switch. The end positions switch power on or off; the middle position selects Mute. An extra power indicator allows the transmitter's status to be checked without removing it from the belt.

The microphone connects through a mini-XLR socket. The skin-colored headset sits behind the neck, with its steel support resting on the ears. The design allows the microphone to be fitted on either side. The gooseneck is long enough for comfortable placement in front of the mouth. A foam windscreen protects the capsule.

Experience in use

We tested the AuraSonics STAGE 200 in real use at a music event. We used the two-channel STAGE 202DR receiver with handheld and bodypack transmitters. Our main goals were to check stability, including while moving the transmitters actively, and to assess microphone sound quality.

We were pleased with the results. In our view, the system performed very well. Setup and operation caused no difficulty, and deployment took only minutes. There were no failures, signal losses, or audible artifacts during movement. Our only wish was for a higher-level receiver line output.

The capsules sounded unexpectedly good. For affordable equipment, the microphones perform at a very good level and are fully suitable for professional work. The handheld transmitter suits singing as well as speech. Voice through the STAGE 200DBT sounds full and convincing. EQ recommendations are the same as for any handheld microphone: use a low-cut filter and add presence for clarity if needed. Performers and speakers should minimize unnecessary handling. The thick plastic reduces some mechanical noise, but extra movements still travel through the housing to the capsule and enter the signal path.

In our view, the headset microphone is even more interesting. Unlike the handheld transmitter, it sometimes needs no EQ at all. Voice already sounds pleasant, bright, and detailed. Continuous sensitivity adjustment makes it easier to set the right level for each performer's voice and technique.

Conclusions

The AuraSonics STAGE 200 feels like a complete professional system for many tasks. These range from simple presentations and events to more demanding vocal performances where sound quality is essential. Its affordable price makes it one of the most attractive wireless systems on our market.
