Operation

401x QUAD Receiver

1. Powering the Receiver

Plug the 16V AC/DC ADAPTER (1) provided into the DC INPUT JACK (11) Then plug the power supply into an AC outlet. [Note: Any 16V DC can also be used.]

on the back of the receiver. source with 800mA capability

Turn VOLUME CONTROL (6) for all four channels counterclockwise to mimimum located on the front of the receiver. Once the receiver is connected to a power source, press the POWER SWITCH (3) to ON position. The POWER ON LED (4) indicator will light up.

The TX LED INDICATOR (7) on the front panel of the receiver will not light up until one or more of the four channels is receiving a signal from your system’s transmitter.

2. Antennas

The ANTENNAS (2) assembly consists of two antennas. Connect antennas into the ANTENNA JACKS (5) on the front of the receiver. Extend the antennas fully to obtain maximum range.

Position ANTENNAS (2) at 45 degrees from the horizontal; 90 degrees from each other. For maximum range, it is always best to maintain a line of sight (no obstructions) between the receiver antennas and the transmitter whenever possible.

3. Mute (Squelch) Adjustment

In normal operation, the MUTE CONTROL (9) should be set fully counterclockwise to the factory preset minimum RF level of 1μV for maximum sensitivity. Doing so sets each receiver for maximum range. However, in areas of high RF activity, the mute (or squelch, as it is sometimes called) may need to be adjusted to compensate for the adverse conditions in a particular location. If, with the transmitter off, its corresponding LED on the receiver front panel flickers or stays on, the MUTE CONTROL (9) should be turned clockwise until the LED extinguishes. For each of the four channels, when the Mute is properly adjusted, the corresponding LED will light only when the system’s transmitter is turned on. Turning the MUTE CONTROL (9) too far clockwise will result in reduced range, but yield a quieter signal during dropouts or at the end of the operating distance range.

4. Connecting the Audio Output

The output stage of each channel and the separate four channels mixed output of the 401X QUAD are all configured for adjustable unbalanced LINE and fixed balanced XLR line or microphone audio outputs. The adjustable unbalanced ¼” mix out is a low level LINE with an output impedance of 600 ohms. The individual fixed level balanced XLR out can be configured as high level line out with 11k ohms output impedance or microphone level out with a 600 ohms load impedance.

For each channel you wish to use, insert an audio cord with a balanced female XLR plug into its

AF OUTPUT (10) jack on back of the receiver. Plug the other end of each cord into your amplifier, effect or mixing board. Adjust volume on your mixing board so that no audio distortion in present when amp or mixer is set at its usual level. [Note: To prevent possible undesired noises during use, leave the volume controls of unused channels (with the corresponding transmitter off) turned off in the amp or mixer. The audio should only be “live” if the transmitter is on.]

If you want to use the 401X QUAD as it own mixer (your amplifier, effect or mixing board should have 12dB or more gain select on), you can connect to the MIX AF OUTPUT (8) which provides a mixed line output of up to all four channels, with the relative volume of each channel in the mix determined by that channel’s VOLUME CONTROL (6).

401XQLTOSYSAB, 401XQUADLTE4F, 401XQ2HT2LTE4FHE specifications

Nady Systems has consistently pushed the boundaries of wireless audio technology, and their latest offerings, the 401XQ2HT2LTE4FHE, 401XQUADLTE4F, and 401XQLTOSYSAB, exemplify this commitment to quality and innovation.
