1 DESIGNATIONS AND FUNCTIONS OF PANEL CONTROLS

ENGLISH Power switch (POWER) When the POWER switch is turned ON (¢ ), the Power indicator w lights. When the Power switch is turned ON, power is supplied to the unit. It takes a few seconds after the power is turned on for the unit to warm up. This is due to the built-in muting circuit that eliminates noise during the on/off operation. Power indicator This indicates the set’s operating status. The indicator flashes red for several seconds when the power is turned on and when the position of the EQ POWER switch e and BALANCED INPUT switch y is changed, indicating that the muting circuit is activated (interrupting the speaker output). In the normal operating mode, the indicator is orange when the EQ POWER switch e is set to the OFF (£) position, green when it is set to the ON (¢) position. Also, if the protective circuit is activated (due to a shortcircuit in the speaker output, DC output to speakers, abnormal temperature rise, etc.), the indicator flashes red and the speaker output is interrupted. In this case, turn the power off immediately, then check the connections, etc. Phono equalizer power switch (EQ POWER) When set to the ON (¢) position, the power of the phono equalizer circuit turns on, and when set to the OFF (£ ) position, the power of the phono equalizer circuit turns off. When this switch is operated, the muting circuit is activated for several seconds, interrupting the speaker output. After flushing red, the Power indicator w is green when this switch is turned on, orange when it is off. Set this switch to the ON ( ¢ ) position when playing records (analog discs). (Also set the INPUT SELECTOR i to the PHONO position.) For sources other than records, we recommend setting this switch to the OFF (£) position for higher sound quality. Balance control knob (BALANCE) This knob is used to adjust the balance between the left and right channels. When it is set to the center position, the amplitude of the amplifier is equal on both sides. If the volume on the right side is too low, turn the knob to the right (,). If the volume on the left side is too low, turn the knob to the left (.). This will achieve an even balance on the left and right sides. Volume control knob (VOLUME) This knob controls the overall volume level. Turn the knob to the right (,) to raise the volume and to the left (.) to lower it. BALANCED INPUT switch (BALANCED INPUT) When set to the ON (¢) position, the source connected to the BALANCED INPUT terminals on the rear panel is selected, regardless of the position of the INPUT SELECTOR i. When set to the OFF ( £ ) position, the source is set to the source selected with the INPUT SELECTOR i. When this switch is operated, the muting circuit is activated for several seconds, interrupting the speaker output.

Recording output selector switch (REC OUT SELECTOR) Use this to select the output source for recording onto a tape deck, etc.

• SOURSE: Set to this position when recording. The recording output is the source selected with the BALANCED INPUT switch y and the INPUT SELECTOR i. In case of recording from turntabel, set the EQ POWER switch e to the ON (¢) position.
• OFF: In this position, the recording output is turned off. For higher quality playback sound, we recommend keeping the selector at this position when not recording.
• TAPE-1 1 2: Use this position when making copies of tapes etc., using two recorders. The input signal from the recorder connected to the TAPE-1/CD-R input terminals is fed to the TAPE-2/MD REC OUT terminals, regardless of the position of the BALANCED INPUT switch y and the INPUT SELECTOR i.
• TAPE-2 1 1: Use this position when making copies of tapes etc., using two recorders. The input signal from the recorder connected to the TAPE-2/MD input terminals is fed to the TAPE-1/CD-R REC OUT terminals, regardless of the position of the BALANCED INPUT switch y and the INPUT SELECTOR i. ENGLISH

ENGLISH Use these to select the program source.

• TAPE-2/MD: Use this position when using the tape deck, etc., connected to the TAPE-2/MD terminals.

• PHONO: Use this position when using the record player connected to the PHONO terminals. Pin 2 : Cold

NOTE: Set the EQ POWER switch e to the ON (¢) position.

NOTE: The PMA-SA1’s speaker output has a BTL configuration, so inverted phase signal is fed to the “>” terminal same as noninverted phase signal is fed to the “<” terminal. Do not use these terminals to connect a device (such as an audio channel selector) for switching between multiple amplifiers or for any type of connection (speaker matrix connection, etc.) other than the normal speaker connections (see page 9). Such connections may result in damage.

• DVD/AUX: Used to play a component such as a HiFi video player, TV tuner or tape deck that is connected to the DVD/AUX terminals.

Speaker system terminals (SPEAKER SYSTEMS) Connect the speaker systems here.

• TUNER: Used to play a component such as an FM/AM tuner or a TV tuner that is connected to the TUNER terminals. Input terminals (INPUTS) These are input terminals for CD players, turntables, AM/FM tuners, tape decks or other playback components. NOTE: The PHONO input terminals are equipped with a short pin-plug. Remove this plug to connect a record player. Store the removed short pin-plug in a safe place so as not to lose it.

• CD-2: Used to listen a CD player or other component that is connected to the CD-2 terminals.

BALANCED INPUT terminals (BALANCED INPUT) These are cannon input terminals for connecting a CD player or other playback component equipped with balanced outputs. The polarities of the pins are as follows:

• TAPE-1/CD-R: Use this position when using the tape deck, etc., connected to the TAPE-1/CD-R terminals.

• CD-1: Used to listen a CD player or other component that is connected to the CD-1 terminals. Recording output terminals (REC OUT) These are recording output terminals for connection to tape decks or other recorders.

AC inlet receptacle (AC IN) Connect the included power supply cord here. Do not use any other cord than the provided power supply cord. Ground terminal (SIGNAL GND) Connect the turntable’s ground wire here. NOTE: This terminal is used to reduce noise when a turntable, etc., is connected. It does not provide grounding.

ENGLISH ENGLISH 2 CONNECTIONS CAUTION Connecting the speakers

• Use speakers with an inpedance of 4 to 16 Ω/ohms.
• The protective circuit may be activated if speakers with other impedances are connected.
• Be sure to connect the cords between the speaker terminals and speaker systems with the same polarities (< to <, > to >). If not, the central sound will be weak and the position of the different instruments will not be clear, diminishing the stereo effect.
• When connecting the speakers, be sure that the conductors of the speaker cords do not stick out from the terminals and touch other terminals, each other or the rear panel.
• Connecting the speaker cords q Peel off the sheathing from the end of the cord. w Twist the conductors. e Turn the speaker terminal counterclockwise to loosen it. r Insert the conductors of the cord entirely, then turn the terminal clockwise to tighten it. Twist the conductors or terminal processing is carried out. Speaker terminal Speaker cord

Protective Circuit This set is equipped with a high speed protective circuit. This circuit protects the internal circuitry from damage due to large currents flowing when the speaker terminals are not completely connected or when an output is generated by a short circuit. This protective circuit’s operation cuts off the output to the speakers. In such a case, be sure to turn the power off and check the connections to the speakers. Then turn the power on again. After muting for several seconds, the set will operate normally. NOTE: NEVER touch the speaker terminals when the power is on. Doing so could result in electric shocks. ENGLISH ENGLISH Cautions on Connections

• Do not plug in the power supply cord until all connections are completed.
• Be sure to connect the left and right channels properly.
• Insert the plugs securely. Incomplete connections can result in noise.

• The PHONO input terminals have an extremely high sensitivity, so avoid turning up the volume when no pin plug cords are connected. Doing so may result in induction humming (booming) from the speakers. When pin plug cords are not connected, insert the included short-circuit pin plug.
