AKG Acoustics WMS61, WMS81 specification

3.Mute indicator: When this red status light is on, the system is muted, indicating low or no RF signal from the transmitter. The squelch action operates with a pilot tone from the transmitter and requires no manual adjustment at the receiver. It is the level of this signal that automatically mutes the system, preventing a rise in noise when the RF signal is low or non-existent.

4.RF level: This consists of a set of 5 LED status lights. When RF signal strength is high, all five are lit, and proper operation is underway. When only the lowest light (yellow) is lit, there is minimal RF input to the system. This is an indication to the operating engineer to take measures, such as changing channel assignments or rearranging the antenna array, so that the RF level can be increased.

5.Diversity status, A and B: These LEDs indicate on an instantaneous basis which of the two internal diversity channels is in operation. In normal use there should be nearly random switching back and forth between the two. If one of the status lights remains on much of the time it is an indication that the operating engineer should slightly rearrange the antennas or shift to another frequency. Constant switching of the LEDs indicate the receiver is searching for the signal, and this the normal mode of operation.

6.AF level: The audio frequency level indicator shows the actual output of the receiver. Normal peak outputs should be in the range of -4 to 0 dB, with the green LEDs on, and occasional peaking of the red LED. This level may be set with the front panel volume control using the small screwdriver.

7.Channel selector: The channel selector is set with the small screwdriver and must match the channel set on the transmitter. (Unlike the transmitter, you do not need to turn the receiver off when selecting a new frequency.)

Here are descriptions of the back panel controls:

1.Antenna A and B connections. These are the BNC bayonet-type lock receptacles at the left and right edges of the back panel. Insert the two “rabbit ear” antenna elements, pointing them upward and slightly outward. Adjust the length of the antenna sections using the guide on the top of the receiver. Note that there are suggested antenna lengths for the various transmission frequency master sets that are available for the WMS 61 and 81 product groups.

2.Signal outputs: You have your choice of three operating modes:

A.Line level unbalanced out at 1/4-inch receptacle.

B.Line level balanced. Use XLR-M receptacle with switch in “line” position.

C.Microphone level balanced. Use LR-M receptacle with switch in “mic” position.

3.Power in: Power for the SR 61 and 81 systems is normally by way of a wall 12 to 16 volt ac or dc power unit plugged into the power receptacle on the back of the unit. Excess wire length may be looped around one of the small brackets for strain relief. Power may also be supplied from the PS 61 or 81 through the antenna coaxial cable.

WMS61, WMS81 specifications

AKG Acoustics has been a leading name in professional audio equipment for decades, renowned for its innovative designs and superior sound quality.

The WMS81 also includes a high-quality handheld transmitter with an AKG D5 microphone capsule, known for its excellent feedback rejection and vocal clarity. This makes it particularly suitable for dynamic performances where clarity and volume are essential. Additionally, the WMS81 offers a wide frequency response, ensuring that every nuance of the performance is captured.

On the other hand, the AKG WMS61 is a versatile system that provides excellent sound quality and flexibility. It features a compact bodypack transmitter designed for use with lavalier or headworn microphones, providing hands-free operation that is perfect for presentations or theater performances. The WMS61 includes a diverse selection of frequency channels, enabling users to operate multiple systems simultaneously without interference. Its sturdy construction ensures durability, which is essential for the rigors of touring and frequent use.

Both systems utilize AKG's renowned audio technologies, including their high-frequency response and low distortion characteristics. Another key feature of these systems is the automatic frequency selection capability, allowing users to easily find the best available channel in crowded RF environments. They also both come equipped with an efficient battery management system, offering extended operational time to ensure reliability during long events.

In summary, the AKG WMS81 and WMS61 wireless microphone systems are excellent choices for anyone looking for high-quality audio performance in a wireless format. Their robust features, advanced technologies, and user-friendly designs make them suitable for a wide range of applications, from live performances to corporate events. With AKG's commitment to innovation and quality, both systems promise to deliver exceptional sound and reliability for audio professionals and enthusiasts alike.
