The Rotel RC-1572MKII is a high-performance stereo control amplifier. Before making any connections, ensure all components in your system are turned off. Always turn the volume control down before turning the amplifier on or off to protect your speakers. Ensure the unit has at least 10 cm of unobstructed clearance for ventilation. Do not use extension cords; connect the unit directly to a wall outlet.
Controls and Connections
The front panel features the Power switch, headphone output, source selection buttons, volume control, and menu navigation buttons. The rear panel contains a comprehensive array of inputs and outputs:
- Analog Inputs: Phono (with ground terminal), CD, Tuner, Aux, and Balanced (XLR) inputs.
- Digital Inputs: Coaxial 1 & 2, Optical 1 & 2, and PC-USB.
- Outputs: Mono Subwoofer out, Preamp out, and Balanced (XLR) output.
- Control/Data: Rotel Link, EXT REM IN, 12V Trigger, RS232, and Network connection.
Setup and Installation
For optimal performance, place the unit on furniture designed to house audio components to reduce vibration. Keep power cords, digital cables, and analog signal cables separated to minimize interference. Use high-quality shielded cables for all connections. When connecting a turntable, use the Phono input and connect the ground wire to the ground terminal. For PC-USB, Windows users may need to install the provided driver for USB Audio Class 2.0 support.
Operation
The unit can be operated via the front panel or the supplied RR-AX93 remote control. The display shows the selected source, volume level, and tone settings. You can adjust volume, balance, and tone controls (Bass/Treble). Tone controls can be bypassed for the purest sound. The display and power LED brightness can be adjusted via the Dimmer control.
Settings Menu
Access the settings menu by pressing the MENU button on the front panel or SETUP on the remote. Key settings include:
- Tone Control: Adjust Bass and Treble levels or enable Tone Bypass.
- Power Option: Configure for Normal or Quick power modes.
- USB Power: Set the rear USB port to provide power in standby mode.
- Auto Power Off: Set a timer for automatic standby.
- Fixed Gain: Configure a fixed volume level for specific inputs.
- Network: View status and configure IP settings.
- Main: Check software version and perform updates.
Troubleshooting
If you encounter issues, follow these steps:
- Power Indicator Not Illuminated: Check the power outlet and ensure the power switch is on. If it still fails, the internal fuse may be blown; contact your dealer.
- No Sound: Verify all cable connections between the source, amplifier, and speakers.
- Cannot Connect via Bluetooth: Delete the previous connection memory on both the amplifier and your device, then attempt to pair again.
