Setup

1. Initial Connection

Before connecting any devices, ensure the receiver is powered off and unplugged from the wall outlet.

• HDMI Connections: Connect your source devices (e.g., Blu-ray player, gaming console, cable box) to the HDMI IN ports on the rear panel. Connect your TV or projector to the HDMI OUT (TV ARC) port. The STR-DH740 features 4 HDMI inputs and supports 4K pass-through and 3D pass-through.
• Audio Return Channel (ARC): If your TV supports ARC, connect the HDMI OUT (TV ARC) port on the receiver to the ARC-compatible HDMI input on your TV. This allows audio from your TV to be sent back to the receiver through the same HDMI cable.
• Speaker Connections: Connect your speakers to the corresponding terminals on the rear panel. The receiver supports a 7.2 channel configuration. Ensure correct polarity (+ to + and - to -) for all speakers.
• Antenna Connection: Connect the FM and AM antennas for radio reception.
• USB Connection: For iPod/iPhone music and video playback, connect your device to the USB input on the front panel.

2. Digital Cinema Auto Calibration (DCAC)

The Digital Cinema Auto Calibration (DCAC) system automatically optimizes sound settings based on your room acoustics and speaker placement. This ensures the best possible sound experience.

1. Connect the supplied auto calibration microphone to the AUTO CAL MIC jack on the front panel.
2. Place the microphone at your primary listening position.
3. Follow the on-screen instructions (via the graphical user interface) to start the calibration process. The receiver will emit test tones to measure speaker distances, levels, and frequency responses.
4. Once calibration is complete, disconnect the microphone.

3. Power On and Initial Settings

After all connections are made, plug in the receiver and power it on. Use the on-screen graphical user interface to adjust initial settings such as input assignments, audio modes, and network settings (if applicable).

• Advanced Blu-ray Disc Audio Decoding: Experience sound closer to its original recording with LPCM, Dolby TrueHD, ProLogic IIz, and DTS-HD Master Audio codecs.

3. Video Features
