FAQ

1. Double the power:

   • If you use the SA40 and PA40 together, you can double the power of your audio system. This is achieved by each of the two devices supplying only one loudspeaker with its mono output stages. This concentrates the full power of each amplifier on a single speaker.
     
     

2. Improved sound quality:

   • The increased power allows each speaker to be driven more precisely and dynamically. This results in a clearer and more powerful sound reproduction, which is particularly advantageous at higher volumes and in larger rooms.

To utilize the full potential of the SA40 & PA40 set, please connect the components as follows:

1. Set the SA40 to “MONO (Bridged)” using the rear panel “Amplifier Mode” switch.
2. Set the PA40 to “MONO (Bridged)” using the rear panel “Amplifier Mode” switch.
3. Use a mono RCA cable to connect the left RCA output "PRE OUT (L)" of the SA40 to the left RCA input "AMP IN (L)" of the PA40.
4. Connect your right speaker to the two outer speaker terminals of the SA40 using a speaker cable. Please note the polarity (+ and -).
5. Connect your left speaker to the two outer speaker terminals of the PA40 using a speaker cable. Please note the polarity (+ and -).
   
   

An external amplifier offers numerous benefits that can significantly enhance the audio quality and flexibility of your system:

1. Improved Sound Quality:
   External amplifiers are designed to provide high power and excellent sound quality, often with better components and signal processing.
   
   
2. Increased Power:
   External amplifiers typically offer higher output power, leading to more dynamic and powerful sound reproduction.
   
   
3. Reduced Distortion and Noise:
   High-quality external amplifiers minimize distortion and noise, resulting in a cleaner and clearer sound.
   
   
4. Enhanced Reliability and Durability:
   Fewer components and a simpler design reduce the likelihood of faults and increase the lifespan of the devices.
   
   
5. Cost Efficiency:
   By focusing on essential functions and avoiding unnecessary features, production costs are lowered, offering high-quality audio equipment at a more attractive price.

Choosing the right amplifier depends on various factors tailored to your specific needs and audio system. Consider the following criteria:

1. Power (Watts):
   Ensure the output power matches your speaker requirements and room size.
   
   
2. Impedance Compatibility:
   Make sure the amplifier is compatible with your speaker’s impedance.
   
   
3. Number of Channels:
   Select the number of channels based on your setup needs.
   
   
4. Amplifier Class:
   Different classes (A, AB, D) offer different benefits regarding efficiency, sound quality, and heat management.
   
   
5. Signal-to-Noise Ratio (SNR):
   Higher SNR means less noise relative to the useful signal.
   
   
6. Total Harmonic Distortion (THD):
   A lower THD value (<1%) ensures more precise and distortion-free sound reproduction.
   
   
7. Cooling and Build Quality:
   Ensure the amplifier has good cooling and robust design.
   
   
8. Input and Output Options:
   Check for necessary connections like RCA, XLR, or speaker terminals.
   
   
9. Brand and Reliability:
   Opt for a reputable brand with good reviews and reliable customer service.
   
   
10. Value for Money:
    Compare features and performance with the price to get the best value.

Connecting an external amplifier to an AV receiver can significantly enhance your system’s audio performance. Follow these steps:

1. Preparation:
   Ensure all devices are turned off and unplugged.
   
   
2. Connecting Pre-Outs:
   Locate the pre-out connections on your AV receiver and connect them to the amplifier’s inputs using suitable cables (RCA or XLR).
   
   
3. Channel Selection:
   Ensure the correct pre-out connections for the speaker channels you wish to drive with the external amplifier.
   
   
4. Connecting Speakers:
   Connect your speakers to the amplifier’s speaker outputs, ensuring correct polarity.
   
   
5. Check Connections:
   Verify all connections are secure.
   
   
6. Power On:
   Turn on the amplifier first, then the AV receiver.
   
   
7. Receiver Settings:
   Configure the AV receiver to enable the pre-out channels and ensure the speaker configuration is correct.
   
   
8. Calibration and Testing:
   Perform automatic or manual calibration to adjust speaker levels and distances.

Bi-Amping involves using separate amplifiers to independently drive the high and low frequencies of a speaker system, offering several benefits:

1. Improved Sound Quality:
   Reduces distortion and enhances clarity by separating frequency amplification.
   
   
2. Increased Power:
   Provides more dynamic sound by having two amplifiers work in parallel.
   
   
3. Reduced Intermodulation Distortion:
   Minimizes distortion by having each amplifier work in a specific frequency range.
   
   
4. Better Channel Separation:
   Enhances stereo imaging and precise instrument placement.
   
   
5. Efficient Amplifier Performance:
   Reduces thermal stress and increases amplifier efficiency.
   
   
6. Adaptability:
   Allows for different amplifiers for different frequency ranges to suit personal preferences.
   
   
7. Extended Control:
   Offers more control over fine-tuning the audio system.

Using Bi-Amping with multi-channel amplifiers, especially in a 5.1 system with a 7-channel amplifier, can be advantageous. Follow these steps:

1. Check Speakers:
   Ensure your speakers support Bi-Amping.
   
   
2. Wiring the Speakers:
   Remove the metal bridges between the high and low terminals and connect separate cables for each frequency range.
   
   
3. Connecting to the Amplifier:
   Use the remaining two channels of your 7-channel amplifier for Bi-Amping the front speakers.
   
   
4. Receiver Settings:
   Configure the AV receiver to support Bi-Amping and assign the correct channels.
   
   
5. Calibration:
   Perform a calibration to adjust speaker levels and distances.
