Häufig gestellte Fragen - CA140Q HARMAN KARDON

Wie schließe ich den Harman Kardon CA140Q an die Autobatterie an?

Verbinden Sie das rote Stromkabel mit der Klemme +B des Verstärkers und dem Pluspol der Autobatterie. Das schwarze Massekabel kommt an die GND-Klemme und direkt an die Karosserie. Den Remote-Anschluss mit dem Remote-Ausgang des Radios verbinden. Achten Sie darauf, dass der Sicherungshalter nahe der Batterie angebracht ist.

Welche Lautsprecherimpedanz ist am CA140Q erlaubt?

Der Verstärker arbeitet mit 4-Ohm- oder 2-Ohm-Lautsprechern. Der Schalter 2Ω/4Ω muss entsprechend eingestellt werden. Im Brückenbetrieb sind nur 4-Ohm-Lautsprecher zulässig.

Wie stelle ich den Eingangspegel am CA140Q richtig ein?

Drehen Sie den Input Level-Regler zunächst auf Minimum. Spielen Sie Musik mit mittlerer Lautstärke ab und erhöhen Sie den Regler langsam, bis die gewünschte Lautstärke erreicht ist. Vermeiden Sie Übersteuerung.

Was bewirkt der 50-Hz-Boost-Regler?

Der 50 Hz Boost hebt die Bassfrequenzen um bis zu 12 dB an, um schwache Tieftonwiedergabe auszugleichen. Stellen Sie die Equalizer am Radio auf Neutral und justieren Sie den Regler nach Wunsch.

Kann ich den CA140Q im Brückenbetrieb (Bridged) verwenden?

Ja, schalten Sie den 2Ω/4Ω-Schalter auf 2Ω. Verbinden Sie einen 4-Ohm-Lautsprecher mit den linken Plus- und rechten Minus-Klemmen eines Kanalpaars. Achten Sie auf korrekte Polarität.

Was bedeutet die Schutzschaltung (Protection) und wann wird sie aktiv?

Der Verstärker schützt sich bei Übertemperatur, Verpolung oder Kurzschluss. Bei Aktivierung wird die Ausgangsleistung stummgeschaltet. Nach Beseitigung der Störung schaltet er sich automatisch wieder ein.

Wie wechsle ich die Sicherung am CA140Q?

Verwenden Sie ausschließlich eine 30-A-Auto-Sicherung vom gleichen Typ. Ziehen Sie vor dem Wechseln das Netzkabel ab.

Der Verstärker wird sehr heiß. Ist das normal?

Ja, es ist normal, dass der Verstärker warm wird. Sorgen Sie für ausreichende Belüftung. Bei Überhitzung schaltet die thermische Schutzschaltung ein. Reinigen Sie das Gehäuse regelmäßig von Staub.

Wie schließe ich zwei Lautsprecher pro Kanal an?

Stellen Sie den 2Ω/4Ω-Schalter auf 2Ω. Verbinden Sie die Lautsprecher parallel an den Klemmen. Achten Sie darauf, dass die Gesamtimpedanz nicht unter 2 Ohm fällt.

Welche Art von Cinch-Kabeln sollte ich verwenden?

Verwenden Sie hochwertige, abgeschirmte Koaxialkabel mit fest sitzenden RCA-Steckern, um Störungen zu vermeiden.

FEATURES

■ 30 Amperes of HCC (High Instantaneous Current Capability) maintains a wide dynamic range and low distortion when driving low impedance or reactive loads.
■ High Power Output of 35 watts per channel into 4 Ohms, 35 watts per channel into 2 Ohms and 70 watts bridged into 4 Ohms.
■ Ultrawide Bandwidth is achieved by the use of inherently fast open-loop circuitry. This improves transient accuracy and phase linearity.
■ Low Negative Feedback Highly linear circuitry produces low distortion with only 25dB of negative feedback. This further improves dynamic accuracy.
■ Discrete Component Audio Circuitry is used because it was found to be the only way to provide HCC, Ultrawide Bandwidth and Low Negative Feedback.
■ A High Capacity Power Supply enables stable operating voltages even under high power conditions. This results in improved low frequency sound quality.
■ High Heat Dissipation Capability is provided by a large heatsink, efficient circuitry and rugged circuit components.
■ Protection Circuitry assures reliability under high temperature, reverse-voltage and short-circuit conditions, without degrading the sound quality during normal high power operation.
■ Simultaneous Stereo/Bridged Operation provides operating flexibility, system simplicity and added value.

GENERAL INSTRUCTIONS

• Be sure that metal objects or other foreign materials do not enter the unit. This can cause immediate trouble or reduce the unit's long-term reliability.
• It is natural for this unit to become warm while operating. It incorporates thermal protection circuitry to shut off the unit when operating abnormally.
• It is recommended that this unit be operated in a vehicle only while the engine (and electrical charging system) is running. At high power output, it typically draws about as much current as an automobile's headlights, and therefore can eventually discharge the battery.
  ● The speaker output terminals are protected from damage due to short-circuited speakers or speaker wires. When this protection circuitry is momentarily activated, the power output is muted for several seconds and is then restored. When the terminals are continuously short-circuited, the power output will remain muted. Should the latter occur, shut off the unit and check the speakers and speaker wires.
• The heat generated by this amplifier is dissipated into the air by the entire chassis. If it is covered, or becomes dirty so that the circulation of the air around it is reduced, the unit's ability to dissipate heat will also be reduced. Under most conditions, the heat dissipating capability of this unit is more than enough to provide uninterrupted operation. However, when full power is drawn in an already hot environment, any loss in heat dissipating capability is likely to result in activating the thermal protection circuits.
• When replacing the fuse, be sure to use an identical value (CA140Q: 30 ampere, CA70: 15 ampere) auto fuse.
• If your unit behaves abnormally, turn it off immediately and consult an authorized Harman Kardon Service Station.

JACKS, TERMINALS AND CONTROLS

INSTALLATION INSTRUCTIONS

Locate and drill 4 holes corresponding to those in the chassis. Securely mount the amplifier to the surface with the four 5 mm tapping screws. Drill undersized holes in the car chassis so that the 5 mm tapping screws fit tightly. We recommend 3.5 mm or 1/8 inch diameter holes.

CONNECTIONS

General

Caution 1: The ignition key switch should be turned off before any connections are made to the car electrical system.

Caution 2: Use a flat-bladed screwdriver with a blade width of less than 5 mm to connect the cables. Using a screwdriver with a blade width of more than 5 mm can damage the screw slot.

Caution 3: The last connection to be made should be to the positive terminal of the car battery.

Caution 4: Do not connect any of the CA70 or CA140Q speaker terminals to the car chassis or to a common ground. Also, do not connect the speaker terminals of the CA70 or CA140Q to the input terminals of another amplifier or signal processor.

Connect the CA140Q/CA70 to the car electrical system and to the other components in the audio system as per the following instructions:

Remote

This terminal enables the power switch of the car tuner/CD or tuner/deck to also turn on the CA140Q/CA70. Connect one end of the accessory yellow cord to the appropriate lead (power amplifier remote) on the car tuner/CD or tuner/deck and the other end to the remote terminal on the CA140Q/CA70.

If a specific wire for this purpose is not provided on the tuner/deck, use the wire for controlling the power antenna. If that wire is already connected to the power antenna, the CA140Q/CA70 can be connected in addition.

+B

The +B terminal is the positive power input terminal. It should be connected to the positive (+) terminal of the car battery using the accessory red cord. The cord should be installed such that the attached fuse holder is located near the car battery.

GND

This is the negative power input terminal. It should be connected directly to the car chassis using the accessory black cord. It is not necessary to connect this terminal to the negative battery terminal.

Input Jacks

These input jacks are for connection to the line (preamplifier) output jacks on the car stereo or tuner/deck. It is recommended that high quality shielded coaxial cables with tight-fitting RCA plugs be used for this connection.

If the car in-dash unit has a built-in power amplifier and does not have line (preamplifier) output jacks, connect the speaker wires to these input jacks. Male phone plugs (not provided) are required. If the built-in amplifier is the "High Power" type (rated 12 watts per channel or more), a power-line adaptor (not provided) must be used.

Adjusting Input Level and 50 Hz Boost Controls

Input level - This continuously variable control allows the amplifier's sensitivity to be matched to the output level of the in-dash unit. Initially, set this control to a low position. Turn on the car audio system and attempt to play it at a comfortable listening level. If the volume control on the in-dash unit cannot increase the level sufficiently, increase the input level control setting accordingly.

50 Hz boost - This continuously variable control can add up to 12 dB of boost to low frequencies in the 50 Hz range. This can be used to compensate for the poor low frequency response from some car speaker systems. Set the bass and treble controls on the in-dash unit to their center positions. Defeat or bypass an equalizer, if used. While the car audio system is playing at a comfortable listening level, increase the setting of the 50 Hz boost control until the desired low frequency effect is achieved.

Stereo (CA70) and 4-channel (CA140Q) Systems

CA70

The following instructions and illustration as shown left apply to typical 2 and 4 channel systems, where one 4 Ohm speaker system is used per channel, and 2 or 4 line output connectors are provided by the in-dash unit.

Note: CA140Q only – The input 1 jacks and the controls on their right side correspond to the speaker 1 terminals. The input 2 jacks and the controls on their left side correspond to the speaker 2 terminals.

CA140Q - Connect two pairs of signal leads from the in-dash unit to the input jacks on the CA140Q. Connect the left and right front leads to the input 1 jacks, and the left and right rear leads to the input 2 jacks. If the in-dash unit has only one pair of output leads, "Y" connector may be used so that the left lead can connect to the left jacks for both input 1 and input 2, and the right lead can connect to the right jacks for both input 1 and input 2.

- Set the 2 / 4 switch to the 4 position.

CA70 - Connect one pair of signal leads from the in-dash unit to the input jacks on the CA70. Connect one pair of speaker systems to the left and right speaker terminals. Set the 2Ω/4Ω switch to the 4Ω position.

- If two 4 Ohm speaker systems are to be connected to each channel, set the 2/4 switch to the 2 position.

In this mode of operation, two channels work together so that their combined power can be driven into one speaker system. Only 4 Ohm speaker systems can be used in this way.

CA140Q - The left input signal must be fed to both input 1 jacks, and the right input signal must be fed to both input 2 jacks. Two "Y" connectors (not provided) are required. Connect the left loudspeaker from the left "+" to the right "-" terminals of speaker 1. Connect the right loudspeaker from the left "+" to the right "-" terminals of speaker 2. Be sure to connect each speaker's positive terminal to the left "+" terminals.

- Set the 2Ω/4Ω switch to the 2Ω position.

CA70 - The same input signal must be fed to each channel. This can be done by connecting a "Y" connector (not provided). One 4 Ohm speaker system should be connected with its positive terminal connected to the left "+" terminal, and its negative terminal connected to the right "-" terminal.

● The 2/4 switch should be set in the 2 position.

When passive crossover networks are available, both mid-high speaker systems and woofers can be connected to the same terminals.

First, connect the mid-high speaker systems and their high-pass networks to the left and right speaker terminals. Be sure to maintain the correct polarities. Also, be sure to connect the amplifier's speaker terminals to the network inputs and the speaker systems to the network outputs.

Next, connect the low-pass network and woofer from the left "+" to the right "-" terminals, with the network's "+" input connected to the left "+"

Two such systems can be used with the CA140Q.

Three Channel Operation - CA140Q Only

This system configuration can be used to drive one stereo pair of speakers in the mid-high frequency range and one mono woofer. An active crossover network (not provided) is required.

Note: * If only one mono jack is provided, a "Y" connector can be used.

Connect a pair of signal leads from the in-dash unit to the active crossover. Connect the mid-high crossover output jacks to the left and right input 1 jacks. Connect the mono low output jacks to the left and right input 2 jacks.

- If only one mono jack is provided, a "Y" connector can be used.

Connect the left and right mid-high speaker systems to the left and right speaker 1 terminals. Connect the woofer from the left "+" to the right "-" terminal of speaker 2. Connect the speaker's positive terminal to left "+"

- Set the 2Ω/4Ω switch to the 2Ω position.
