The Burmester 948 is a high-end power conditioner designed to enhance the audio quality of hi-fi systems by isolating them from power line noises. It incorporates several advanced features to ensure optimal performance and protection for connected audio components.
The primary function of the Burmester 948 is to provide complete isolation for a hi-fi system from both high and low-frequency power line noises. This is achieved through its active DC compensation, a patented technology that effectively eliminates low-frequency line noise. Such noise typically causes transformer hum and can significantly impair sound quality. By removing these disturbances, the 948 ensures a cleaner and more transparent power supply to your audio equipment, leading to an improved listening experience.
The device is equipped with eight AC outlets, divided into four groups, to connect various hi-fi components. These outlets are categorized into four filtered and four unfiltered outputs, allowing for flexible power distribution based on the specific needs of your audio setup. Furthermore, the 948 features two separate power filters, enabling the user to keep the power supplies for digital and analogue components distinct. This separation helps prevent interference between different types of devices, further enhancing sound purity.
Beyond noise reduction, the Burmester 948 offers comprehensive system control and protection features. It allows for remote switching of the entire hi-fi system, providing convenience and integration with other Burmester components. The system's star-shaped earthing design offers effective protection against earth loops, which can introduce unwanted noise and hum. An extremely robust additional equipotential bonding conductor ensures optimum earthing, contributing to both safety and performance.
For protection against power fluctuations, the 948 includes highly effective overvoltage protection. This safeguards both the power conditioner itself and all connected devices from power surges, which can cause significant damage to sensitive audio equipment. The device also features a switching display that provides real-time information on the current mains voltage or the DC component present in the mains grid, allowing users to monitor power conditions.
The Burmester 948 is built with precision and robust construction, reflected in its physical dimensions and weight.
In terms of power consumption and output, the 948 is designed for efficiency and high performance:
The device is available in different nominal voltage ranges and models to accommodate various international power standards:
The maximum output per AC outlet must not exceed 2,000 W @ 230 V, 1,550 W @ 120 V, and 1,300 W @ 100 V. The total output for all connected devices must not exceed the maximum power output specified for the respective model.
The Burmester 948 is intended for use in home audio systems and is designed for straightforward operation. All connection terminals are located on the rear of the device, while operating controls are on the front panel, with the exception of the AC mains switch.
Before connecting, ensure the AC mains switch (13) is set to OFF. Connect the power cable's device plug to the AC input terminal (14) and then plug the mains plug into a wall outlet. For optimal listening, connect the side of the mains plug marked with a dot to the 'hot' phase of the wall outlet, which is also marked on the 948's AC outlets. An equipotential bonding conductor is required for safe operation and discharge of overvoltages; it connects to the 948's earth connection (20) and then to a wall outlet.
The eight AC outlets are grouped as follows:
The REMOTE input terminal (19) allows the 948 to be switched on and off remotely from a preamplifier or digital-to-analogue converter. This requires a suitable remote cable, which is not included due to varying length requirements. Devices connected to "SWITCHED" AC outlets will turn on simultaneously with the power conditioner.
The 948 includes various protection circuits.
It is recommended to read the operation manual in full and keep it in a safe place. The original packaging should be kept for future transport or moving.
Never clean the housing with a wet cloth or chemical cleaning agent. Ensure no liquid enters the device.
A three-year warranty is provided, valid if the device has been connected and operated properly without overloading, its mechanical integrity has not been compromised, and the warranty application has been submitted correctly. Opening the device, modifying it, or dismantling outlets will void the warranty.
If the unit does not respond to front panel controls, it can be reset by switching it off and back on using the AC mains switch on the back.
For the cleanest power supply, the use of the triple-shielded BURMESTER-POWER cable is recommended. This cable features three high-purity copper wires with minimal resistance and triple shielding for outstanding electrical and magnetic insulation, promising a clear and detailed sound for the entire hi-fi system.
It is illegal to dispose of this device with household waste. It must be handed over to a municipal collection point or a voluntary returns system.
