3. Setup
3.1. Charging the System
The AC58 system includes a BCA58 Charging Case that provides power to both the transmitter and receiver units. The charging case itself is recharged via a USB-C cable.
- Connect the provided USB-C charging cable to the charging case and a suitable USB power source.
- Place the A58 Transmitter and Receiver into their designated slots within the charging case.
- Press the 'Recharge and Battery Check' button on the charging case once to display the current battery charge level. Press it twice to initiate charging for the units.
- The Battery Charge LEDs on the case indicate the charging status.

3.2. Powering On/Off and Channel Selection
Each A58 unit (transmitter and receiver) has an ON/OFF switch. To ensure proper operation, both units must be powered on and set to the same channel.
- Power On/Off: Use the dedicated ON/OFF switch on each unit.
- Channel Scan Mode: To find the best available wireless channel, hold the receiver's channel button for 3 seconds. The receiver's LED will flash during scanning and then remain steady on the optimal channel.
- Manual Channel Matching: After the receiver completes its scan, manually set the transmitter's channel to match the receiver's selected channel.
3.3. Active and Passive Modes
The A58 wireless guitar system supports both active and passive pickup modes, making it compatible with various guitar types, including those with high-output active pickups.
- Activating Active Mode: For instruments with active pickups, hold the transmitter's Channel button for 3 seconds. The 'Active LED' will illuminate to confirm active mode is engaged.
- Passive Mode: This mode is generally compatible with most guitars or basses. If the input power is too high, leading to audio distortion in passive mode, switch to active mode.

4. Operating Instructions
4.1. General Operation
Once the transmitter and receiver are charged, powered on, and set to the same channel, plug the transmitter into your instrument's output jack and the receiver into your amplifier or pedalboard input. The system operates on a 5.8 GHz frequency band, offering a reliable connection.
4.2. Sound Quality and Range
The AC58 system delivers high-resolution 24-bit/48 kHz audio across a wide frequency range of 20Hz to 20kHz. The 5.8 GHz true diversity wireless system is designed to minimize interference from other wireless devices, providing clear sound whether performing on stage or at home. The system offers a range of over 100 feet.

5. Maintenance
5.1. Battery Life and Charging
The A58 Transmitter and Receiver units offer approximately 5 hours of battery life on a full charge. The BCA58 Charging Case provides up to 2 full charges or multiple top-ups for both units, extending usage time significantly.
5.2. Storage and Care
Store the units in the charging case when not in use to protect them and keep them charged. Avoid exposing the system to extreme temperatures, moisture, or direct sunlight. Clean the units with a soft, dry cloth.
6. Troubleshooting
6.1. Interference Issues
The AC58 operates on the 5.8 GHz band, which is generally less susceptible to interference than 2.4 GHz systems. If interference occurs:
- Utilize the Channel Scan Mode (Section 3.2) to find a clearer channel.
- Ensure no other 5.8 GHz devices are operating in close proximity.
- Maintain a clear line of sight between the transmitter and receiver.
6.2. Audio Distortion
If you experience audio distortion, particularly with high-output pickups:
- Switch the transmitter to Active Mode (Section 3.3). This mode is designed to handle higher input levels from active pickups.
- Verify that both the transmitter and receiver are fully charged.
