trim-pot counterclockwise reduces overall system audio output (thus lowering distortion but raising background noise), while turning clockwise increases overall system audio output (thus lowering background noise but raising distortion). The Audio Level Adjust is factory set to the mid position, which is the optimal setting for normal operation.
Note: The Audio Level Adjust is not intended for high-input signal adjustment—the 15dB pad is provided for that purpose. It is for use only in extreme cases during which satisfactory audio cannot be achieved with the pad alone.
Note: Set control carefully. If trim-pot is turned past minimum or maximum adjustment points, it may need to be backed up to achieve desired setting.
Programming the MT-16A/R to the Selected Channel
Before beginning operation, the MT-16A/R transmitter must be synchronized with the selected frequency from the receiver using the IR Receptor/Sensor Window (21) on the transmitter and the IR Sync Window (1) on the receiver (see Selecting the MGT-16 Receiver Channel and IR Sync on page 8).
After first turning the transmitter on (or off and then on again if already on), begin programming by holding the transmitter’s IR Receptor/Sensor Window about 6-12” from the receiver’s IR Synch Window. Press the IR Sync Button (14) once to begin the IR sync download of the selected frequency to the transmitter. Upon successful data transfer (usually in less than two seconds) the transmitter will transmit a radio signal on the same channel (frequency) as
the receiver. The Signal LED (10) on the receiver will light up, indicating that the link is completed. If all the necessary steps noted above are not taken during the ten seconds of active data transfer, the receiver and the transmitter units will not link and the transmitter’s previously programmed channel remains unchanged.
When programming is finished, close the battery compartment door, ensuring that it latches. The MT-16A/R is now ready for use.
Note: Manually matching the transmitter frequency without the receiver is not possible. For proper operation, the transmitter must have the same channel as selected on the receiver.
Operating the MT-16A/R
Instrument Transmitter
During normal operation with the unit powered On, the MT-16A/R transmitter should be fully inserted onto the instrument (guitar, bass, etc.). When ready to play, slide the Power Switch (2) to On position
in the direction of the arrow. The receiver Signal LED (10) should light up if system is properly synchronized. Adjust the volume on the receiver (see Connecting Audio Output on page 9) for unity gain (one-to- one) with a hard-wired cord. Or, select up to an added 4-5dB boost by adjusting the receiver volume to maximum for normal use with guitars and bass guitars. A listening test prior to use will determine which receiver volume and transmitter input pad settings are best for your application. To Mute/un-Mute (attenuate) the audio during use, set the receiver power switch to the second (Mute) position. Or, just turn off the transmitter with the Transmitter Power Switch (17). The Signal LED will turn off and the audio will be muted (Off). When ready to play again, slide the receiver’s power switch to the third (On) position. Or, just turn on the transmitter.
Note: While playing, the audio level should be adjusted on the instrument as when using a hard-wired cord.
