To enable the rear speakers for movie playback on the Onkyo TX-SR800, follow these steps:

1. Enter Speaker Setup Menu:
- Go to the “1. Speaker Setup” menu.

2. Set Surround Back Speakers:
- In the speaker configuration (Speaker Config), set “Surr Back” to “Small” (or “Large” if applicable) to enable the rear speakers.

3. Verify Surround L/R Settings:
- Ensure “Surr L/R” is also set to “Small” or “Large”.

4. Set Speaker Distance:
- Go to “2. Speaker Distance” and input the correct distances for the surround and surround back speakers.

5. Level Calibration:
- Go to “3. Level Calibration” to adjust the volume level of the surround back speakers for balanced playback.

6. Select Appropriate Listening Mode:
- Choose a mode like “Enhanced 7” or “THX Surr EX” (set to On or Auto) to make use of rear speakers during movie playback.

These steps will configure the TX-SR800 to use the rear speakers for movies.

Page 74: Adjustment And Confirmation Procedures
TX-SR800 ADJUSTMENT AND CONFIRMATION PROCEDURES 1 Idling current adjustment Before Idling current adjustment, turn the trimming resistors R6040 to R6046 to counter-clockwise. Connect the DC voltmeter at the sockets P6080 to P6086. After turn POWER to ON, adjust the trimming resistors R6040, R6041 and R6042 so that the reading of voltmeter becomes 11 mV.
Page 75 TX-SR800 ADJUSTMENT AND CONFIRMATION PROCEDURES 2 3. Confirmation of Current detection circuit Set the unit to "TEST-1-00". Connect the differentiating circuit and apply the 200Hz square signal to MULTI CHANNEL INPUT terminal. of each channel. Adjust the attenuator or Volume so that the output level becomes 35V p-p.
Page 76 TX-SR800 ADJUSTMENT AND CONFIRMATION PROCEDURES 3 Test Mode 1. Turn POWER button on. 2. Press and hold down CD button, then press DISPLAY and STANDBY/ON buttons. 3. After "TEST " on the FL tube is displayed, press CD button to set the unit to the test mode of FL tube.
