Operate four wireless microphones at the same time for conferences, performances, and presentations with the D-450-HT-LT from Nady. This configuration of the system gives users a choice between using a handheld mic for interview-style applications or a more discreet lavalier mic for a lower visual profile. Included are two handheld transmitters featuring built-in microphones with dynamic omnidirectional capsules along with two bodypack transmitters with black omnidirectional lavalier microphones.

The D-450 system operates in the 515 to 598 MHz range of the UHF spectrum and offers a total of 200 auto-scan frequencies (50 for each of the 4 mic channels) to seek out a clean transmission channel, helping to ensure clear audio free from dropouts and interference at a maximum line-of-sight range up to 300'. The all-digital system offers resolutions of 24-bit / 48 kHz to provide crisp, intelligible speech and vocal reproduction for a wide range of applications and events.

• This configuration of the D-450 system includes 2 handheld microphone/transmitters, each with an On/Off switch
• Backlit LCD screens show you frequency, battery status, and RF signal strength
• The mic capsules are designed to minimize handling noise and feature unidirectional (cardioid) pickup patterns that help to reject off-axis sound for less feedback when sound reinforcement equipment is used
• Two AA alkaline batteries will power each transmitter for up to 10 hours
• Roadworthy, durable metal casing ensures a long lifespan

• This configuration of the D-450 system includes 2 lightweight bodypack transmitters, each with a power/mute switch, and 6-stage volume control
• Metal belt clips securely attach the transmitters to presenters and performers
• Each transmitter features a locking 3.5mm connector to accommodate its discreet lavalier microphone, which quickly and easily secures to the talent's clothing via an integrated alligator clip
• The lavalier mics feature omnidirectional polar patterns that pick up sound 360° around the capsule, providing consistent volume, even if the subject isn't speaking directly toward the microphone
• Backlit LCD screens on the transmitters show you frequency, battery status, and RF signal strength
• Two AA alkaline batteries will power each transmitter for up to 10 hours
• Roadworthy, durable metal casing ensures a long lifespan

• The single quad-channel receiver allows you to easily work with 4 microphones at the same time
• The Auto-Scan feature automatically searches 200 frequencies to provide clear transmission channels for the microphones
• Infrared (IR) auto-sync pairing provides lightning-fast synchronization of the transmitters to selected channels/frequencies
• 4 balanced XLR outputs and a 1/4" unbalanced mix output are on the rear panel
• Volume controls are provided to mix the mic channels to the summed 1/4" output
• 4 removable front-mounted antennas allow for optional hassle-free rackmounting

Related Questions and Answers

Q: 1. I have one of these units that has frequencies 907.7, 921.2, 912.8, 927.5 MHz. Can I add a second unit with your frequencies?

A: Yes, you can use the Nady DW-44-LT-HM Four-Channel UHF Wireless Microphone System with Four Lavalier Mics & Four HM-3 Headsets (Black, B1: 905.8 to 925.9 MHz) with another DW-44 system that operates on the 907.7, 921.2, 912.8, 927.5 MHz frequencies. As long as each system operates on different frequencies, there should not be any issues.

Q: 2. Does the unbalanced line out from the receiver plug directly into the 1/8" / 3.5 mm TRS Stereo Microphone Input of a DSLR or do I need some sort of adapter?

A: The Line output connection from the receiver in the Nady DW-44-LT-HM Four-Channel UHF Wireless Microphone System with Four Lavalier Mics & Four HM-3 Headsets will be too loud to connect directly to the 3.5mm Mic input connection of a DSLR camera and will arrive distorted in most cases. This connection could be attenuated with a cable such as the Whirlwind WHH4NL3.5 Line-to-Microphone Attenuator Cable for HDSLR Cameras (BH #WHH4NL3.5) if the output connection is converted to 3.5mm female first.

Q: 3. Could this be used as an input and output of an audio interface to a macbook pro for streaming?

A: This would connect to the input of your interface and work to transmit the microphone audio while streaming. There would be no way to monitor wirelessy.

Q: 4. What are the dimensions of the receiver?

A: It's not tiny... I have one at home that I use with a DDJ WEGO2 and its around 7 x 4 x 1.5 inches.

Q: 5. How does battery charging work here?

A: The transmitter within the Nady PEM-02 Wireless 2-Person In-Ear Monitoring System uses an AC power supply, and the included bodypack receivers use AA batteries. If the AA batteries chosen are rechargeable, they should have their own proprietary charger.

Q: 6. Will the receiver transmit static when the mics are turned off?

A: Whether a receiver creates noise while unpaired to its correlating transmitters is not a specification that manufacturers make known. In theory, the receiver in the Nady DW-22 HTHT Digital Wireless Microphone System should not present any extra noise when not paired to the microphone transmitters. However, as this device operates on open channels, it is susceptible to RF activity in the surrounding area, which could manifest as audible static noise.

Q: 7. Can I get extra receivers?

A: Yes you can use additional Nady PEM-RX receivers but these are not available standalone at B&H.

Q: 8. Can you remove the antennas?

A: No, the antennas in the rear of the DW-22 receiver are not removable, but they can be adjusted for tilt and angle.

Q: 9. What are the choices of frequencies. Already have 915.30 aand 916.80?

A: The entire DW-22 series are 900mHz: https://bhpho.to/3gpl5Qh

Q: 10. Does this product allow separate mix for each receiver or do all users get the same output?

A: The Nady PEM-04 allows one unbalanced input for each individual channel, and two sum inputs that are sent to all channels.
