5. Connecting the Audio Output
O P E R A T I O N
The output stage of each channel and the separate mixed output of all four channels of the 401 VHF are all configured for unbalanced lines, with an output impedance of 600 ohms to accommodate both balanced and unbalanced lines.
For each channel you wish to use, insert an audio cord with a 1/4” mono plug into its AF OUTPUT (10A) jack on the back of the receiver. Plug the other end of each cord into your amplifier, effects or mixing board. Turn VOLUME CONTROL (11) on 401 VHF Receiver clockwise to near full gain. Adjust volume up or down so that no audio distortion is 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 401 VHF as its own mixer, you can connect to the MIX AF OUTPUT (10B) which provides a mixed output of up to all four channels, with the relative volume of each channel in the mix determined by that channel’s VOLUME CONTROL (11).
a. Instrument Connection (using the
Insert an audio cord with a 1/4” mono phone plug in the AF OUTPUT JACK (10A) on the rear panel of the receiver. Plug the other end of the cord into an amplifier, effects, or mixing board. Adjust the VOLUME CONTROL (11) on the 401 receiver clockwise to about 3/4 rotation until the volume level is comfortable for your applica- tion. This setting is roughly equivalent to a direct instrument cord connection. Turning the volume up to maximum will provide 4dB gain over a cord.
b. Microphone Connection (using the
To use the 1/4” line level AF OUTPUT JACK (10), follow the instructions for the Instrument Connection (above), except start with the receiver volume at 1/2 MAX and adjust the volume control until the volume level is optimal. If the volume control is set too high, you may overload your mixer or amp.
