Chapter 2:

Connecting up

Making cable connections

Caution

• Before making or changing the connections, switch off the power and disconnect the power cord from the AC outlet.
• Connect the power cord after all the connections between devices have been completed.

Caution

• The SIGNAL GND terminal is provided to reduce noise when connecting the unit to components such as an analog turntable.
• The PHONO IN terminals are factory equipped with short pin plugs. These should not be removed except when connecting a turntable. Be sure to save the short pin plugs in a safe place.
• Do not insert the short pin plugs in any connectors other than the PHONO IN terminals. Connecting them to any other terminals may cause malfunctions.
• Do not connect the PHONO IN terminals to any component other than a turntable; also, do not connect to a turntable equipped with built-in equalizer. An excessively high sound output may be produced, resulting in damage to your speakers or other devices.
• The A-50's PHONO IN terminals are designed to be used only with turntables equipped with MM (moving-magnet) type cartridges. Turntables equipped with MC (moving-coil) cartridges cannot be used.
• Make sure not to bend the cables over the top of this unit (as shown in the illustration). If this happens, the magnetic field produced by the transformers in this unit may cause a humming noise from the speakers.

• The unit's POWER AMP DIRECT terminals should never be connected to any other component's connectors except PRE-AMP OUT.
• If your turntable has a grounding wire, secure it to the ground terminal on this amplifier.

Note

• When connecting a tape cassette deck, playback noise may be heard, depending on the installation location. This noise is caused by leakage flux from the amplifier's transformer. In this event, change the installation location, or move the deck farther from the amplifier.

• iPod is a trademark of Apple Inc., registered in the U.S. and other countries.

About "Bi-wiring"

This unit can be used with speakers that support biwiring. Be sure to connect the high-frequency and low-frequency connections correctly.

• During playback, be sure that both the SPEAKERS A button and SPEAKERS B button are set to ON (page 8).

Caution

• When using bi-wiring to connect speakers, avoid adverse affects on the amplifier by being sure to remove the HIGH and LOW short bars provided with the speakers. For detailed information, consult the instructions provided with the speakers.

• When using speakers with removable network circuits, note that if the network is removed, no effect will be produced and damage may be caused to the speaker.

• Another method of connection is to connect the SPEAKERS A terminals to HIGH and the SPEAKERS B terminals to LOW (reverse that shown in the illustration).

Connecting speaker cables

1 Twist the cable cores.
2 Loosen the nut on the SPEAKERS terminal, and insert the speaker cable into the exposed hole in the terminal shaft.
3 Retighten the terminal nut.

Caution

• When using only one set of speaker terminals (SPEAKERS A or SPEAKERS B), or when utilizing bi-wiring connections, the speaker used should have a nominal impedance between 4 Ω and 16 Ω. When using both sets of terminals, the connected speakers should have nominal impedance between 8 Ω and 32 Ω. Consult the instructions accompanying your speakers for details regarding the impedance value.
• Make sure the positive and negative (+/-) terminals on the amplifier match those on the speakers.
• These speaker terminals carry HAZARDOUS live voltage. To prevent the risk of electric shock when connecting or disconnecting the speaker cables, disconnect the power cord before touching any uninsulated parts.
• Make sure that all the bare speaker wire is twisted together and inserted fully into the speaker terminal. If any of the bare speaker wire touches the back panel it may cause the power to cut off as a safety measure.

Connecting audio cables

Connect the white plug to the left (L) jack, and the red plug to the right (R) jack. Be sure to insert the plugs fully into the jacks.

Using centralized control with other Pioneer components

Multiple Pioneer components equipped with CONTROL IN/OUT jacks can be connected to the unit, allowing centralized control of the components via the remote sensor on the unit. This also allows remote control of components not equipped with a remote sensor, or installed in places where the component's remote sensor cannot be accessed.

Note

• For connections use a commercially available monaural miniplug cord (without resistor).
• When connecting the CONTROL IN/OUT jacks, commercially available audio cords must also be used to make analog connections. Merely connecting the CONTROL IN/OUT jacks alone will not allow proper system control.
• When a control cord is connected to the unit's CONTROL IN jack, the unit cannot be controlled by pointing the remote control at the unit (the remote sensor is automatically disabled).

Wipe off any dirt from connectors and pin plugs. •Confirm that the unit's input selector is set to the desired playback component. Set selector correctly (page 11). •Press MUTE on the remote control to turn muting off (page 10).
No sound from one speaker.	•Are the connection cables or speaker cables disconnected on one side? Reconnect securely (page 5).
Can't operate the remote control.	•Replace the battery (page 4). •Operate within 7 m, 30° of the remote sensor on the front panel (page 4). •Remove the obstacle or operate from another position. •Avoid exposing the remote sensor on the front panel to direct light. •Is the control cord for one component connected improperly? Confirm correct connections (page 6).
Can't change input source.	•Check whether POWER AMP DIRECT function is ON. If so, press the front panel's POWER AMP DIRECT button to turn the function OFF (page 11).
No sound is heard when a linear PCM signal with frequency of 96 kHz or more is input to the DIGITAL IN COAXIAL terminal.	•Sound may not be output properly depending on the digital coaxial cable used; try replacing the cable (sold separately) with another.
When the DIGITAL IN USB port is connected to a computer via USB cable, audio files on the computer cannot be played.	•Has the proper device driver been installed on the computer? When using a USB cable to connect the unit's DIGITAL IN USB port to a computer in order to play audio files on the computer, the proper device driver must be downloaded from the Pioneer website and installed on your computer. Consult the Pioneer website for instructions on installing the driver.
No sound is produced when attempting to play files on a computer.	•Are volume settings correct for the OS and application program? Raise the volume settings as required.
	•Is the OS audio output set to MUTE? Cancel the MUTE setting.
	•Are multiple applications running simultaneously? Try closing applications that are not in use.
	•Has the audio output been set properly within the OS or application used? For audio device select "Pioneer USB Audio Device".

Cleaning the unit

• Use a polishing cloth or dry cloth to wipe off dust and dirt.

• When the surface is dirty, wipe with a soft cloth dipped in some neutral cleanser diluted five or six times with water, and wrung out well, and then wipe again with a dry cloth. Do not use furniture wax or cleansers.

• Never use thinners, benzine, insecticide sprays or other chemicals on or near this unit, since these will corrode the surface.
