Emotiva XPA-1 manual Other Probable Causes of Noise, Problems with the whole A/V System

Ground loop isolators are available for audio lines and video devices. If you need assistance, contact Emotiva. Although this is not always an ideal solution, the grounding differences between

certain home entertainment components sometimes require ground loop isolators. This is the exception rather than the rule.

Other Probable Causes of Noise

Speaker noise may also be caused by interference or noise on your AC line. Make sure there are no large appliances sharing the line, or halogen lamps or light-dimming Triac devices.

•Try connecting your system to another AC socket on a separate line.

•If the hum is heard from within the XPA-1, and not through the speakers, this may also be caused by

interference on the AC or DC lines. The power transformers may turn this interference into an audible noise. Internal hum can be made worse by a shelf or cabinet resonating, so try moving the XPA-1 to another shelf.

•Try moving your components further away from the TV, especially if you ever notice the screen has changed color in the area closest to the component.

•If you have very high efficiency speakers, these may tend to reveal noises which other speakers do not.

One or more RED lights on the Front Panel are Blinking

Each RED light indicates a fault condition for the corresponding power module. A fault condition is one or more of the following:

•Excessive Operating Temperature

•Excessive Current (Short Circuit)

•DC on the Outputs

An excessive temperature fault can be reset by allowing amplifier to cool and cycling power on/off button on the front panel. Excessive current (short circuit) can be reset by removing the cause of the short and cycling power on/off button on the front panel. DC at output is a possible fault condition that is equipment related and requires technical assistance. Please contact Emotiva if you have repeated problems causing the RED front panel light to flash that are NOT thermal or short circuit related.

Problems with the whole A/V System

If you are having more complex problems in your overall home entertainment system (not just with the XPA-1 amplifier), please contact Emotiva for XPA-1 professional installation assistance. These professionals have years of experience with a wide range of home entertainment and lifestyle products and can offer you assistance in troubleshooting and rectifying problems.

XPA-1 specifications

The Emotiva XPA-1 is a powerful and sophisticated monoblock amplifier designed for audiophiles who demand high performance and exceptional sound quality. With a power output of 1000 watts per channel into 8 ohms, and doubling the power to 2000 watts into 4 ohms, the XPA-1 is engineered to drive even the most demanding speakers with ease.

One of the key features of the XPA-1 is its fully balanced design. This configuration minimizes distortion and improves dynamic range by reducing the noise floor, allowing for a cleaner and more detailed sound. The amplifier employs a Class A/B topology, ensuring that sound quality remains pristine while delivering the high power needed for demanding audio applications. This hybrid design combines the efficiency of Class B operation with the low distortion characteristics of Class A amplification.

Thermal management is another critical aspect of the XPA-1. The amplifier is equipped with a robust heat sink and thermal protection circuitry, ensuring that it operates safely and efficiently even during extended listening sessions. The design allows for quiet operation, minimizing the impact of fan noise, a common concern with high-power amplifiers.

The XPA-1 features high-quality components, including custom-wound toroidal transformers, which provide a stable power supply. This contributes to the amplifier's impressive transient response and dynamic capability, allowing it to handle complex musical passages and peak demands effortlessly. Additionally, the use of high-grade capacitors further enhances performance, ensuring that audio playback is not only powerful but also accurate and lifelike.

Another notable feature is the XPA-1's RCA and XLR inputs, providing versatile connectivity options for various audio sources. This enhanced flexibility allows users to integrate the amplifier seamlessly into their existing audio systems, whether for home theater setups or high-end stereo configurations.

Emotiva's attention to detail extends to the build quality of the XPA-1. With a sleek and sturdy chassis, the amplifier is designed to endure the rigors of everyday use while complementing any high-end audio environment. The front panel features a unified design with neatly arranged controls, making it user-friendly and aesthetically appealing.

In summary, the Emotiva XPA-1 is a high-performance monoblock amplifier that combines advanced technology, exceptional power output, and robust build quality. Its fully balanced design, powerful Class A/B amplification, and high-quality components make it an attractive option for audiophiles looking to elevate their sound systems to new heights. Whether for music or home theater applications, the XPA-1 delivers an uncompromising listening experience that truly captivates.
