TX-SR600/E 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. Confirm that the speaker relay does not turn OFF when a 3.0 ohm load is connected. Confirm that the speaker relay turns off when a 1.5 ohm load is connected. Caution:Don't continue more than 3 seconds.

Confirmation of voltage sensor 1. Set the unit to Test-3-4. 2. Apply the signal 1kHz, -15dBV to the MULTI-CH input. Confirm that the FM STEREO is displayed. Confirm the all channels except SUBWOFFER. 3. When connect the resistor 2.7 kohm/1 W between the terminals COM and TH1 of P6301, confirm that "FM STEREO" light on. Note: No input signal. 4.When set the unit to "Test-4-30,confirm that the speaker relays of RL6901 and RL6902 turn off. Note: No input signal.
