Digital Receiver Digital Hybrid Wireless® Technology All wireless links suffer from channel noise to some degree, and all wireless microphone systems seek to minimize the impact of that noise on the desired signal. Conventional analog systems use compandors for enhanced dynamic range, at the cost of subtle artifacts (known as “pumping” and “breathing”). Wholly digital systems defeat the noise by sending the audio information in digital form.

DSQD Manual Navigating the Menus All Setup Menu items are arranged in a vertical list on the LCD. Press MENU/SEL to enter the menu, then navigate with the UP and DOWN arrows to highlight the desired setup item. NOTE: To guarantee chosen parameters are saved, exit a setup screen BEFORE powering down DSQD.

Digital Receiver Group Tune Assign a tuning group to a channel. Group Tune Setup Tuning groups allow the user to set up a list of frequencies, allowing for easy tracking of frequency tuning in the transmitters. Use MENU/SEL to move through the options and UP arrow to make a selection. • Four tuning groups are available, U, V, W, X. • Each group has the option to add or delete a frequency from the list on the right.
DSQD Manual Diversity Setup Diversity is a DSQD feature that safeguards against loss of audio signal caused by RF interference. The DSQD architecture allows three different types of diversity reception. Once chosen, the diversity mode is shown on other screens with a link icon. (Visit the DSQD page on lectrosonics.com for a video with more details on Diversity.
Digital Receiver • Frequency: Again, the receiver channels are paired. In this mode, each channel is set to a different frequency. The DSQD automatically uses whichever receiver’s RF signal quality is better. The use of separate frequencies helps minimize dropouts caused by multi-path phenomenon. This technique uses both switched and ratio diversity for maximum effectiveness. NOTE: To maximize frequency diversity, choose frequencies separated as far apart as possible.
DSQD Manual Audio Setup Menu • JA HYB: Used only for certain digital hybrid transmitters marketed in Japan Audio Level Set audio output level with the level control. The mute button is a toggle used to mute or unmute the audio output. The TONE check box is used to generate a 1 kHz test tone at the audio output. Talkback Setup Audio Polarity Select normal or inverted polarity for each audio channel. Smart Noise Reduction Three levels of noise reduction are available: High, Normal and Off.
Digital Receiver 1. Begin by selecting a key type. Choose Transmitter: Choose one of four Rx channels by using the Channel Selector Buttons, 1, 2, 3 or 4. Hold and press the Channel Selector Button to initiate sync. 2. The DSQD will then display a warning to indicate that there is NO KEY! Select CREATE KEY to generate a new key. NOTE: You must position the transmitter’s IR port directly in front of the DSQD IR port, as closely as possible, to guarantee a successful sync.
DSQD Manual TX Battery Timer Alert Set transmitter battery timer alerts for each channel. Choose to enable/disable alert, set time in hour and minutes and reset timer. Use MENU/SEL to set and move the cursor and the UP and DOWN arrows to change values. Network Settings Allows the user to set network settings when needed. The following controls are available: • DHCP Enable - this is checked if DHCP is used to assign an IP address, Netmask and Default Gateway to the device.
Digital Receiver Restore Defaults Returns all settings to the factory defaults. If YES is chosen, message will appear and DSQD will reboot. Pilot Tone Bypass In Digital Hybrid compatibility mode ONLY, Turn Pilot Tone Bypass on/off. Locale Locale optionally changes the settings on the DSQD based on the region where the receiver is being used.
