5. Connecting the Audio Output
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 WGT-15 instrument transmitter)
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 WLT-15 transmitter with either a headset or
lavalier microphone or the WHT-15 handheld microphone transmitter)
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.
