3.1. Njikọ Ntinye ọdịyo
The MM7055 offers both balanced (XLR) and single-ended (RCA) inputs for each channel. Choose the input type that matches your pre-amplifier or AV receiver's outputs for optimal signal integrity.
- XLR (Balanced) Inputs: For professional-grade connections, connect XLR cables from your pre-amplifier's balanced outputs to the corresponding XLR inputs on the MM7055.
- RCA (Single-Ended) Inputs: For standard connections, connect RCA cables from your pre-amplifier's RCA outputs to the corresponding RCA inputs on the MM7055.
- Ensure that the input selector switch (if present, or automatically detected) for each channel is set correctly for the type of cable used.
3.2. Njikọ Ọkà Okwu
The MM7055 features gold-plated, four-way binding post speaker terminals. Use high-quality speaker wire for the best performance.

Connect the detachable power cord to the AC inlet on the rear of the amplifier, then plug the other end into a suitable wall outlet.
4. Ntuziaka ọrụ
4.1. Ịgbanye / gbanyụọ
- Ka ike na amplifier, press the "POWER ON/STANDBY" button located on the front panel. The illuminated porthole display will light up.
- Iji tinye amplifier into standby mode, press the "POWER ON/STANDBY" button again.
- For total remote control convenience, the MM7055 includes input and output jacks for DC trigger pulses as well as RC-5 jacks, allowing integration with compatible control systems.
4.2. Ngwugharị ọdịyo
Once connected to a pre-amplifier or AV receiver, the MM7055 will amplify the audio signals received from your source components. Adjust the volume and select audio modes via your pre-amponye na-anata ma ọ bụ AV.
The MM7055 is ideal for a 5.1 home theater system, providing powerful and clear audio for movie soundtracks and music. For more complex home theater systems, the MM7055 can be paired with one or several MM7025s (sold separately) to create an immersive 7.1 or 9.1 audio experience.
5. Nlekọta
5.1. Nhicha
To maintain the appearance of your amplifier, wipe the exterior surfaces with a soft, dry cloth. Do not use abrasive cleaners, waxes, or solvents, as these may damage the finish. Ensure the unit is powered off and unplugged before cleaning.
5.2. Igwe ikuku
The MM7055 employs an extruded aluminum thermal tunnel with temperature-sensing forced air cooling for efficient heat dissipation. Ensure adequate ventilation around the amplifier to prevent overheating. Do not block any ventilation openings. This configuration assures cool operating temperatures for long-term reliability, even under substantial output.
6. Nchọpụta nsogbu
If you experience issues with your Marantz MM7055, please consult the following common troubleshooting steps before seeking professional service.

- Chọpụta na oghere mgbidi na-enye ike (jiri ngwaọrụ ọzọ nwalee).
- Check if the "POWER ON/STANDBY" button has been pressed.
- Enweghị ụda:
- Confirm that all audio input cables (XLR or RCA) are securely connected between the pre-amplifier/receiver and the MM7055.
- Check all speaker wire connections at both the amplifier and the speakers, ensuring correct polarity (+ to + and - to -).
- Verify that your pre-amplifier/receiver is powered on, has a source selected, and its volume is turned up.
- Ensure the correct input type (XLR/RCA) is selected on the amplifier if there is a manual switch (though typically auto-sensing).
- Ụda agbagọ:
- Lelee njikọ eriri niile maka ikesa ma ọ bụ mmebi.
- Ensure speaker wires are not frayed or shorting.
- Reduce the volume level from your pre-amplifier/receiver to see if distortion persists, indicating potential clipping.
- Verify that the impedance of your speakers is compatible with the ampna -emegharị ihe.
- ekpo oke ọkụ:
- Gbaa mbọ hụ na amplifier has adequate ventilation and is not placed in an enclosed space without airflow.
- Remove any objects blocking the ventilation openings.
- Allow the unit to cool down if it has been operating at high volumes for extended periods.
The chassis of the MM7055 is heavy gauge steel, designed to provide maximum isolation from external vibration and minimize electromagnetic and radio frequency interference, contributing to clear, uninterrupted sound.
