Storing the packing materials After unpacking, store the cardboard box and packing materials in a safe place; do not throw them away. If you are to transport the RDA-7 at a later date, you will need this cardboard box and the packing materials. The RDA-7 is very heavy and may become damaged if it is transported in a different box. Inner carton Outer carton (Shipping carton) Inner carton Pad Pad Poly bag 家电维修资料网 RDA-7 4 On Standby On Power O f f Seven Channel Amplifier RDA-7 Front panel facilities Power On / Off Pressing this switch connects the RDA-7 to the main Power outlet and the On indicator lights blue. Sound will be heard after approximately 9 seconds. If you want to operate the RDA-7 using a 12-volt trigger, connect to the 12V TRIGGER terminal of a control amplifier or pre- amplifier and leave the Power switch of the RDA-7 set to On. For example, to control the RDA-7 while it is connected to the RDC-7 AC controller, connect the 12V TRIGGER A jack of the RDC-7 to the 12V TRIGGER IN jack of the RDA- 7 with a 3.5-mm (1/8-inch) mini-jack cable. If a plug is connected to the 12V TRIGGER IN jack: The signal reaches the 12V TRIGGER, the On indicator lights blue. When there is no signal at the 12V TRIGGER, the Standby indicator lights red. On/Standby The RDA-7 is equipped with two indicators to display its status. If both indicators are off, then the main Power switch on the front panel is turned off. If the Power switch is turned on, then one of these indicators will be lit. On: Lights blue when Power is supplied from the AC mains Power supply. Standby: Lights red when no signal is input from the 12V TRIGGER IN terminal and the RDA-7 is in the Standby state. Note: If the Power switch is pressed and neither indicator lights, check that the Power cord is properly connected and that a fuse has not blown. If the indictors still do not light, turn off the RDA-7, disconnect the Power cord, and contact an Onkyo service station or representative. If the On indicator lights blue and the Standby indicator flashes red, the protection circuitry of the RDA-7 has activated. The protection circuitry activates if a problem such as a speaker cord shorting or the temperature of the RDA-7 rising excessively occurs. Turn off the RDA-7, remove the cause of the problem, and then turn the RDA-7 back on. If the problem is still not solved, turn off the RDA-7, disconnect the power cord, and contact an Onkyo service station or representative. 家电维修资料网 RDA-7 5 INPUT SELECT / This switch is located between the balanced input and single-ended RCA input for each channel. Use this switch to select the input type for its channel. Note: • Do not change the INPUT SELECT switch setting when the RDA-7 is turned on. Rear panel facilities and connections Unbalanced Input (single end RCA input) Connect controllers or pre-amplifiers with single-ended outputs for high-quality sound. Note: • When using this single-ended connection for a specific channel between the pre-amplifier and RDA-7, set the INPUT SELECT switch to the RCA input side to select single-ended input. Next, use high- quality cables and connect the single-ended output from the pre-amplifier to the corresponding single- ended input on the RDA-7. • Do not connect anything to the balanced input jack. Note: • When using this balanced connection for a specific channel between the pre-amplifier and RDA-7, set the INPUT SELECT switch to the XLR input side to select balanced input. Next, use high-quality cables and connect the balanced output from the pre-amplifier to the corresponding balanced input on the RDA-7. • Do not connect anything to the RCA-type audio input jack. The pin assignments for this terminal are given above. This pin assignment conforms to the standard adopted by the Audio Engineering Society. Refer to the instruction manual supplied with the pre-amplifier and verify that its output terminal is compatible with the pin assignments for this terminal. If it does not, wire it so that the output pins connect with the proper input pins. Connector ground terminal: Chassis grounded 2. Disconnecting the input terminal Pull out the connection cord while holding down the lever. Balanced Input (XLR terminal) Connect controllers or pre-amplifiers with balanced outputs for high-quality sound. Precaution for connection This unit comprises 7 independent power amplifiers, each being capable of reproducing the same quality sound through its channel. Note that you should connect an input source and a speaker to each channel in use. For channels that are not in use, we recommend that you do not connect any input source or speaker. 1 2 3 1.

Push 家电维修资料网 RDA-7 6 Rear panel facilities and connections Fuse The RDA-7 uses a 250V AC slow-blow (time lag) main fuse. To replace the fuse, insert a coin or similar object into the groove, turn it to the left, and remove the fuse. Replace only with the same type and same rating. The correct fuse rating will differ depending on the voltage of your set as given here. 120V:T15A/250V 220V/230V/240V:T10A/250V AC INLET Plug the supplied Power cord into this AC INLET and then into the Power outlet on the wall, Caution • Do not connect any devices other than speakers to these terminals. Also, never short-circuit the output from these terminals. • Be sure not to mistake the positive and negative outputs or the left and right speakers. Doing so will result in an unnatural sound space. • Only connect speakers with an impedance of 4 ohms or greater. If a speaker with an impedance of less than 4 ohms is connected, it may damage the RDA-7. • Do not connect more than one speaker cable to one output terminal. Doing may damage the RDA-7. Be sure to read “Phasing your speaker system” and “Speaker ratings” on the following page. • Do not use a Power cord other than the one supplied with the RDA-7. The Power cord supplied is designed for use with the RDA-7 and should not be used with any other device. • Never have the Power cord disconnected from the RDA-7 while the other end is plugged into the wall outlet. Doing so may cause an electric shock. Always connect by plugging into the wall outlet last and disconnect by unplugging from the wall outlet first. Ground If connecting the unit to another equipment causes noise such as a hum, you may improve the reproduced sound quality by connecting this terminal to the grounding terminal of the connected equipment with a lead wire. 5-12 volts, positive tip polarity 1 3 4 5 2 15 mm (5/8 inch) Warning Before replacing the fuse or making any electrical connections, always turn off the Power and disconnect the Power cord. 12V TRIGGER IN/OUT Connect the 12V TRIGGER IN jack to control amplifiers that have a 12V TRIGGER output jack, such as the RDC- 7. This jacks works on between 5 to 12 volts DC. With the Power switch of the RDA-7 set to On, you can switch the RDA-7 between the on and Standby states with operations at the control amplifier. If you want another component to be activated by turning on and off the control amplifier connected to the 12V TRIGGER IN jack of the RDA-7, then connect the 12V TRIGGER input jack of that component to the 12V TRIGGER OUT jack of the RDA-7. In this state, even if the RDA-7 is turned off, the signal from the control amplifier passes through the RDA-7 and goes out the 12V TRIGGER OUT jack. Daisy chaining is also possible using these jacks. Use φ3.5-mm (1/8-inch) monaural-type mini-jack connectors. The tip polarity of the connectors are as shown below. 1. Strip away 15 mm (5/8 inch) of wire insulation. 2. Twist wire ends very tight. 3. Unscrew 4. Insert wire 5. Screw + OUTPUT – (Speaker output and binding post) The RDA-7 is equipped with high-current binding posts for use at output terminals to the speaker system. To obtain the best in sound quality from the RDA-7, we recommend the use of high-quality speaker cables. For each channel, connect the negative (or black) output post to the negative (or black) input terminal of the speaker and the positive (or red) output post to the positive (or red) input terminal of the speaker. Make the connections following the procedure given below. • Make sure that connections have been made only to the inputs selected with the INPUT SELECT switches and nothing is connected to the other ones.

Connect the assembled channel to the power transformer and turn it ON. 2. After about 9 seconds the two green LED's should turn ON 3. Measure the following voltages and make sure they are within the specifications: For all these measurements connect the DC voltmeter negative lead to the bottom lead of the VR8 zener diode. C7 (+) 70V +/- 3V C9 (-) -70V +/- 3V L1 0V +/- .1V 4. Connect a DC voltmeter to the test points TP1 and TP2 and adjust the voltage to 4mV using the R46 BIAS adjustment trimpot. 5. Allow the channel to warm up for 30 minutes, adjusting the bias every ten minutes. 6. Measure the output DC voltage and adjust it as close to zero as possible using the R24 trimpot. Main Chassis Test 1. Assemble the chassis/power supply and configure it for right line voltage. 2. Plug it into the power line. 3. Turn the unit ON. The blue ON LED should come ON. 4. Red Fault/Standby LED should be flashing. 5. Turn the unit OFF and plug a remote control plug into the Remote IN jack. 6. Turn the unit ON. The Red Standby LED should be ON. 7. Apply 12V to the remote control plug. The unit should turn ON, the blue LED should be ON and the red LED flashing. 8. Measure the secondary voltages on all power cables going to the channels. Each secondary should read 50VAC +/- 2VAC. Final Assembly Test 1. Install all channels in the chassis and turn the unit ON. All green LED's should come ON after about 9 seconds. 2. Check bias currents on all channels and adjust if necessary. 3. Allow the unit to warm up for 30 minutes, adjusting the bias currents every ten minutes. 4. Adjust the DC output voltage as close to zero as possible on each channel. 家电维修资料网 RDA-7 19 Pcboard Component side view from circuit side Circuit side view from component side 家电维修资料网 RDA-7 20 RDA-7 Primary Connections For Different Voltages AC Board Jumpers For voltages in the 100V - 120V range, install the two jumpers marked L For voltages in the 200V - 240V range install the single jumper marked H Main Transformer Jumpers The following connections should be made for different line voltages: 100V: K1-3 to BL1-4, P7 to BL1-3 P2 to BL1-2 K2-3 to BL1-12, P8 to BL1-11 P3 to BL1-10 110V: K1-3 to BL1-6, P7 to BL1-5 P2 to BL1-2 K2-3 to BL1-14, P8 to BL1-13 P3 to BL1-10 120V: K1-3 to BL1-8, P7 to BL1-7 P2 to BL1-2 K2-3 to BL1-16, P8 to BL1-15 P3 to BL1-10 200V: K1-3 to BL1-4 BL1-2 to BL1-3 K2-3 to BL1-12 BL1-10 to BL1-11 220V: K1-3 to BL1-6 BL1-2 to BL1-5 K2-3 to BL1-14 BL1-10 to BL1-13 230V: K1-3 to BL1-6 BL1-2 to BL1-7 K2-3 to BL1-14 BL1-10 to BL1-15 240V: K1-3 to BL1-8 BL1-2 to BL1-7 K2-3 to BL1-16 BL1-10 to BL1-15 家电维修资料网 RDA-7 21 Inrush Current Limiter Board (RDA-7-030) AC PCB Module (RDA-7-020) P2 BL1 P3 P7 P4 P9 P1 P10 P8 K1-3 K2-3 K2-4 K1-4 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 Low L L H High Jumpers 家电维修资料网 RDA-7 22 POWER SUPPLY SCHEMATIC DIAGRAMS 家电维修资料网 RDA-7 23 DRIVER CIRCUIT 家电维修资料网 RDA-7 24 OUTPUT STAGE AND PROTECTION 家电维修资料网 RDA-7 25 PROTECTION 家电维修资料网 RDA-7 26 AC BOARD 家电维修资料网 RDA-7 27 PROTECTION WIRING 家电维修资料网 RDA-7 28 Printed in Japan 0M3646 N0600 Integra Research Division of ONKYO CORPORATION Sales & Product Planning Div. : 2-1, Nisshin-cho, Neyagawa-shi, OSAKA 572-8540, JAPAN Tel: 072-831-8111 Fax: 072-833-5222 http://www.onkyo.co.jp/ Integra Research Division of ONKYO U.S.A.
