- IR Window: For infrared synchronization with the bodypack receiver.
- VOL Knob: Adjusts the input volume.
- Sync Button: Initiates the synchronization process.
- LCD Display: Shows group, channel, and other system information.
- Group Button: Selects the frequency group.
- Channel Button: Selects the frequency channel within a group.
- ON/OFF Switch: Powers the transmitter on or off.
- Power Jack: Connects to the power adapter.
- Adapter Cord Tie-off: Secures the power adapter cable.
- Loop Out (L/MONO, R): Provides a pass-through of the input audio signal to another device.
- Inputs (L/MONO, R): Connect audio sources (e.g., mixer output) using 1/4" TRS cables.
- PAD Switch: Reduces input signal by -12dB to prevent distortion from excessively loud sources.
- Antenna Jack: Connects the UHF antenna for wireless transmission.
4.2. UHF Bodypack Receiver
The bodypack receiver is a compact, portable unit that receives the audio signal from the transmitter and delivers it to your earphones.

- IR Window: For infrared synchronization with the transmitter.
- Informative LCD: Displays RF signal strength, audio signal level, and battery indicators.
- Power Knob: Controls power ON/OFF and volume.
- Antenna: Receives wireless signals.
- Earphone Jack: Connects to the included earphones or other 3.5mm headphones.
5. Setup Instructions
5.1. Transmitter Setup
- Connect Antenna: Screw the included antenna into the ANT.A jack on the rear of the transmitter.
- Connect Power: Plug the power adapter into the DC 12-18V power jack on the rear of the transmitter. Secure the cable with the adapter cord tie-off.
- Connect Audio Input: Connect your audio source (e.g., mixer's monitor output) to the L/MONO and R INPUTS on the rear of the transmitter using 1/4" TRS cables. For mono operation, you can use a single input.
- (Optional) Loop Out: If you need to pass the audio signal to another device, connect it to the L/MONO and R LOOP OUT jacks.
- Power On: Press the POWER button on the front panel to turn on the transmitter.
5.2. Bodypack Receiver Setup
- Install Batteries: Open the battery compartment and insert two AA batteries, ensuring correct polarity.
- Connect Earphones: Plug the included earphones (or your preferred 3.5mm headphones) into the PHONES jack on the top of the bodypack receiver.
- Power On: Rotate the POWER knob clockwise to turn on the receiver.
5.3. Synchronization (IR Sync)
To establish a wireless connection between the transmitter and receiver:
- Ensure both the transmitter and receiver are powered on.
- On the transmitter, use the Group and Channel buttons to select your desired frequency. The system offers 50 selectable frequencies.
- Press the Sync button on the transmitter. The IR window on the transmitter will begin to flash.
- Align the IR window of the bodypack receiver with the IR window of the transmitter, holding them approximately 1-2 inches apart.
- The receiver's display will show a successful sync message, and the RF signal indicator will illuminate, confirming the connection.
6. Operating Instructions
6.1. Adjusting Volume
- Transmitter Volume: Use the VOL knob on the transmitter to adjust the overall input level. Monitor the audio level on the transmitter's LCD to avoid clipping.
- Receiver Volume: Use the POWER/VOL knob on the bodypack receiver to adjust your personal monitoring volume.
6.2. Frequency Selection
The PTM-11 system operates in the UHF 900MHz band and offers 50 selectable frequencies to minimize interference. If you experience signal dropouts or interference, try changing the frequency:
- On the transmitter, press the Group button to cycle through available frequency groups.
- Press the Channel button to select a specific channel within the chosen group.
- After selecting a new frequency, perform an IR Sync (Section 5.3) to update the bodypack receiver.
6.3. Using the PAD Switch
The PAD switch on the rear of the transmitter (-12dB/0dB) is used to attenuate excessively loud input signals. If your audio source is very strong and causes distortion even with the transmitter's volume turned down, set the PAD switch to -12dB. This helps prevent input overload and ensures a cleaner audio signal.
6.4. Mono Monitoring and Separate Outputs
The PTM-11 system provides mono monitoring, which helps eliminate phase issues and ensures clear, focused audio. The separate L/MONO and R inputs allow for a personal audio mix. The Loop Out feature allows the original audio signal to pass through the PTM-11 transmitter without being affected, enabling connection to other sound equipment.

- Battery Replacement: Replace AA batteries in the bodypack receiver promptly when the low battery indicator appears on the LCD.
- Storage: When not in use for extended periods, remove batteries from the receiver and store the system in its carry case in a cool, dry place.
- Antenna Care: Handle the antenna carefully to avoid bending or breaking.
8. Troubleshooting
