2. To initialize the unitThis device employs a microprocessor to perform variousfunctions and operations. If interference generated by an external power supply, radio wave, or other electrical source results in accident which causes the specified operations and functions tooperate abnormally.To perform a result, please follow the procedure below.

1.Press and hold down the VIDEO-1 button, then press the STANDBY/ON button.2.After "CLEAR" is displayed, the preset memory and each mode stored in the memory, such as surround, are initialized and will return to the factory setting.3. Unplug the power supply cord.

3. Safety-check out(U.S.A. model only)After correcting the original service problem, perform thefollowing safety check before releasing the set to the customer.Leakage Current CheckMeasure leakage current to a known earth ground(water pipe,conduit, etc.) by connecting a leakage current tester between the earth ground and exposed metal parts of the appliance(input/output terminals, screwheads,metal overlays, etc.).Plug the power supply cord directly into a 120V AC 60 Hz outletand turn Standby switch on. Any current meausred must not exceed 0.5mA.

1. Replacing the fuses

This symbol located near the fuses indicates that thefuse used is fast operating type. For continued protection againstfire hazard, replace with same type fuse. For fuse rating refer tothe marking adjacent to the symbol.

Ce symbole indique que le fusible utlise est a rapide.Pour une protection permanente, n'untiliser que fusibles dememe type. Ce darnier est la qu le present symbol estappse.

4.Setting the voltage selector (Worldwide modelsonly)

Worldwide models are equipped with a voltage selector to conformwith local power supplies. Be sure to set this switch to match thevoltage of the power supply in your area before plugging in the unit.

Determine the proper voltage for your area: 220-230 V or 120 V. Ifthe preset voltage is not correct for your area, insert a screwdriverinto the groove in the switch. Slide the switch all the way to theupper (120 V) or to the lower (220-230 V), whichever is appropriate.

5.Setting the AM tuning step frequency(Worldwide models only)

If you are using the Worldwide model (i.e., your TX-SR501/TX-SR501E has a VOLTAGE SELECTOR on the rear panel), you need to set the AM tuning interval for compati-bility with AM broadcasts in your particular country. The ini-tial setting is 9 kHz.

North America: 10 kHz

Other countries: 9 kHz

Note:All presets are deleted when you change this setting.

To set the AM tuning interval, while holding down the [TUNER] button, press the [MEMORY] button.

A COMPONENT VIDEO (10, 12, 14, 16)These RCA/phono connectors can be used to connect a TV, DVD player, or other AV component with component video inputs and outputs.

B AM ANTENNA (22, 23)These push terminals are for connecting an AM antenna.

C FM ANTENNA (22, 23)This connector is for connecting an FM antenna.

D FRONT SPEAKERS B (21)These push terminals are for connecting speaker set B.

E FRONT SPEAKERS A, SURROUND SPEAKERS, CENTER SPEAKER & SURROUND BACK SPEAKER (21)These terminal posts are for connecting speaker set A, includ-ing the front, surround, center, and surround-back speakers. They accept bare wires or banana plugs (European models don’t accept banana plugs).

F AC OUTLET (11)This switched AC outlet can be used to supply power to another AV component. The connector type depends on the country in which you purchased your TX-SR501/TX-SR501E.

G DIGITAL INPUT OPTICAL 1, 2 & COAXIAL (10, 13, 14, 16–18)These optical and coaxial connectors can be used to connect a CD, DVD, or LD (laser disc) player, or other AV component with digital outputs.

H SUBWOOFER PRE OUT (21)This RCA/phono connector can be used to connect an active subwoofer.

I CD IN (10, 17)These RCA/phono connectors can be used to connect a CD player with analog outputs.

J TAPE IN/OUT (10, 17, 18)These RCA/phono connectors can be used to connect a cas-sette recorder, MiniDisc recorder, or other recorder with ana-log inputs and outputs.

K (19)This (Remote Interactive) connector can be connected to the connector on another Onkyo AV component, for example, a CD player, DVD player, or cassette recorder. The TX-SR501/TX-SR501E’s remote controller can then be used to control that component. To use , you must make an ana-log RCA/phono connection between your TX-SR501/TX-SR501E and the other AV component, even if they are connected digitally.

L VIDEO 1 IN/OUT & VIDEO 2 IN (10, 14–16, 39)These connectors can be used to connect a VCR or other AV component. There are RCA/phono connectors for connecting to stereo analog audio inputs and outputs, and S-Video and composite video (RCA/phono) connectors for connecting to video inputs and outputs.

M DVD IN/MULTI CH INPUT (10, 12, 13)The FRONT, SURR, CENTER, and SUBWOOFER RCA/phono connectors can be used to connect AV components with multiple analog audio outputs, including DVD players with individual 5.1 surround analog outputs. There’s an S-Video input and composite video (RCA/phono) input for connecting the video signal.

N MONITOR OUT (10, 12)These S-Video and composite video (RCA/phono) outputs can be connected to the video input on your TV or projector.

O VOLTAGE SELECTOR (Worldwide model only) (5)This voltage selector provides compatibility with power sys-tems around the world.

Tip:A turntable with a built-in preamp can be connected to a pair of unused TX-SR501/TX-SR501E analog inputs. To connect a turntable without a built-in preamp, you’ll need a commer-cially available phono preamp. See pages 17 and 18 and the instructions supplied with your phono preamp and turntable for more information.

After adjustment, attach the top cover.voltmeter becomes 1.5 mV. (Surround and surround back channels)

Confirm the voltage of points above after about five minutes.Front and center channelsWhen less than 7.0 mV, readjust the resistors above so that the voltage becomes 7.0 mV.When 7.0 mV to 9.0 mV, you are not necessary to adjust.When more than 9.0 mV, readjust the resistors above so that the voltage becomes 9.0 mV.Surround and surround back channelsWhen less than 4.0 mV, readjust the resistors above so that the voltage becomes 4.0 mV.When 4.0 mV to 6.0 mV, you are not necessary to adjust.When more than 6.0 mV, readjust the resistors above so that the voltage becomes 6.0 mV.Note: No load and No signal

Confirmation of protection circuit

1. Confirmation of operation of speaker relay Confirm that the speaker relays turn ON approximate. 5 seconds after the power switch is turned ON. Confirm that the speaker relays turn OFF immediately after the power switch is turned OFF.

2. Confirmation of DC detection circuit Press and hold down CD button, then press STANDBY/ON and DVD buttons to set the unit to "TEST-1" mode. After "TEST-1" on the FL tube light on, press SPEAKER B button to set the unit to "TEST-1-00". Apply DC 1.5 to 3V to DVD INPUT terminal with no load. Confirm that the speaker relay turns OFF. Apply DC -1.5 to -3V to DVD INPUT terminal with no load. Confirm that the speaker relay turns OFF. Caution: Don't apply DC voltage more than 1 sec..Note: When surroun back channel, confirm at "TEST-1-01".

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 DVD 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 turn on when a 1.5 ohm load is connected. Caution:Don't continue more than 3 seconds.
