The Lectrosonics SMQV Super Miniature Wireless Microphone Transmitter incorporates Lectrosonics patented Digital Hybrid Wireless technology into a package no bigger than a pager. The SMQV transmitter is miniature in size yet rugged enough to withstand rigorous daily use in the field or in studios.

To meet the demand for both extended operating range and extended battery life, this version of the SMQV transmitter offers a selectable output power of 50 or 100 mW. The 50mW option is provided for some theatrical applications, where the system design specifies lower transmitter power. Channel spacing is also selectable, with 100 and 25 kHz options available. With the spacing set to 100 kHz, the SMQV transmitter offers 180 user-selectable UHF frequencies in this block; if that's not enough, setting the spacing to 25 kHz gives you up to 684 frequencies to work with. 

Lectrosonics patented Digital Hybrid technology revolutionizes wireless microphone transmission. Digital audio signal is converted and encoded for analog transmission, then decoded and converted back to digital audio at the receiver. The result is an exceptionally low noise floor as the compandor circuit is eliminated and clear audio reception is retained at greater distances.

The Switchcraft TA5M audio input has a user-calibrated 44 dB gain range, and accepts electret lavalier mics, dynamic mics, or line-level signals. A DSP-controlled analog audio limiter is employed before the A-D converter. The limiter has a range of more than 30 dB and a dual-release envelope, making the limiter transparent while maintaining low distortion.

The non-corrosive, machined aluminum casing is splash proof and features an LCD display with membrane switch control panel. The transmitter is powered by two AA lithium, NiMH, or alkaline batteries for up to 14.5 hours (lithium). The SMQV transmitter is completely compatible with all Lectrosonics Digital Hybrid wireless receivers as well as older Lectrosonics analog receivers.

Q: 1. Can this receive signals from two separate DBu mono transmitters simultaneousy?

A: Yes, the Lectrosonics DCHR Camera-Mount Miniature Digital Camera Hop Wireless Receiver can be used with two separate Lectrosonics DBu Digital Bodypack Wireless Transmitters at the same time.

Q: 2. How is this receiver different than the DCR822 other than the slot-in size capability?

A: The Lectrosonics DSR Two-Channel Digital Slot Receiver and the Lectrosonics DCR822 Compact Dual-Channel Digital Wireless Receiver are incredibly similar units, and both models are compatible with the same transmitters. The only differences are within secondary characteristics like the type of panel used for the screen (OLED for the DCR822 / IPS for the DSR). Additionally, the DCR822 has onboard recording capabilities via microSDHC and can be powered with AA batteries or DC power. The DSR uses DC power only.
