Parasound Z Amp v3 90W Two Channel Zone AmpManual d'usuari més viu

1. Introducció

The Parasound Z Amp v.3 is a stereo power amplifier designed for custom installations and compact audio systems. It delivers 45 watts per channel into an 8-ohm load, or 60 watts per channel into 4-ohm loads. It can also be bridged to provide over 90 watts mono into 8 ohms. Its compact 'half-width' chassis (1-3/4 inches tall, 9-1/2 inches wide) makes it suitable for various applications, including multi-room audio, PC/desktop audio, and small stereo systems. The Zamp v.3 features fully discrete, direct-coupled DC servo circuitry, high-speed bipolar output transistors, and a high-quality toroid power transformer.

3.2 Connexions del panell posterior

This image displays the rear panel of the Parasound Z Amp v3 amplifier, detailing all input and output connections. Visible features include RCA line-level inputs and loop outputs, speaker binding posts, mono bridge switch, ground lift switch, auto on/manual/12V trigger switch, and independent level controls for each channel.

1. Line-Level Inputs (RCA): Connect your audio source (e.g., preamplifier, multi-room controller) to these inputs.
2. Line-Level Loop Outputs (RCA): Allows you to pass the input signal to another amplifier or audio component.
3. Speaker Binding Posts: Connect your speakers using high-quality speaker wire. Ensure correct polarity (+ to + and - to -). The Z Amp v3 supports 8-ohm and 4-ohm speakers.
4. Interruptor de pont mono: Use this switch to bridge the amplifier for mono operation, providing higher power output to a single speaker (e.g., a subwoofer). Refer to the markings for correct speaker connection in bridged mode.
5. Interruptor d'elevació de terra: Helps eliminate hum caused by ground loops. Try both positions if you experience hum.
6. Auto On / Manual / 12V Trigger Switch:
   • Encès automàtic: El amplifier will automatically turn on when an audio signal is detected.
   • manual: El amplifier is controlled solely by the front panel power button.
   • Disparador de 12 V: El amplifier turns on/off via a 12V trigger signal from another component.
7. Level Controls (L/R): Independently adjust the input sensitivity for each channel to match your source component and achieve ideal gain staging.
8. Entrada d'alimentació CA: Connect the supplied AC power cord here.
9. VoltagSelector: Ensure this is set to the correct voltage for your region (e.g., 115V or 230V).
10. Portafusibles: Contains the main power fuse.

3.3 Speaker Connection Guidelines

For optimal performance and safety, observe the following:

• Ensure speaker impedance is within the amplifier's specified range (4-8 ohms for stereo, 8 ohms for bridged mono).
• Use appropriate gauge speaker wire for your cable length.
• Tighten binding posts securely, but do not overtighten.

4. Instruccions de funcionament

4.1 Engegada/apagada

Depending on the setting of the Auto On / Manual / 12V Trigger switch:

• manual: Press the front panel power button to turn the ampmés viu encès o apagat.
• Encès automàtic: El amplifier will power on automatically when an audio signal is detected at the inputs and power off after a period of no signal.
• Disparador de 12 V: El amplifier will power on or off in response to a 12V trigger signal from a connected component.

4.2 Ajust del volum

La Z Amp v3 does not have a master volume control on the front panel. Volume is controlled by your source component (e.g., preamplifier, receiver) or by the individual Left and Right level controls on the rear panel. Adjust the rear panel level controls to achieve a balanced sound and appropriate gain for your system.

4.3 Ús d'auriculars

Plug your headphones into the front panel headphone jack. When headphones are connected, speaker output will typically be muted.

5. Manteniment

To ensure the longevity and optimal performance of your Parasound Z Amp v3, follow these maintenance guidelines:

• Neteja: Utilitzeu un drap suau i sec per netejar l'exterior ampEviteu netejadors o dissolvents abrasius.
• Ventilació: Ensure adequate ventilation around the unit. Do not block the ventilation slots on the top or sides. Avoid placing the amplifier in enclosed spaces without proper airflow.
• Cable d'alimentació: Comproveu periòdicament el cable d'alimentació per detectar qualsevol signe de dany.
• Connexions: Occasionally check all audio and speaker connections to ensure they are secure.

6. Solució De Problemes

If you encounter issues with your Z Amp v3, consult the following troubleshooting tips:

6.1 Sense poder

• Check if the power cord is securely plugged into the amplificador i la presa de corrent alterna.
• Verify the AC outlet is functional.
• Check the fuse on the rear panel. If blown, replace it with a fuse of the exact same type and rating.
• Ensure the front panel power button is pressed (if in Manual mode) or the Auto On/12V Trigger settings are correct.

6.2 Sense so
