Very often we specify our high capacity ‘off-grid’ battery power system to further optimise the performance of the complete audio system.
This is of benefit even in countries with a stable and dependable grid network.
However in countries with an irregular grid supply it becomes less of a luxury and more of an essential.
The Living Voice Pure Music BPS is a rugged and maintenance-free system designed to be located at a distance from the listening room. It can be housed as far away as an outbuilding.
It can be supplied either as an ‘appliance’ that simply plugs in and plays, or in a format to be installed by your electrician. It can be switched on and off remotely and monitored using your smartphone.
The battery capacity is specified according to the power consumption of the audio system, as well the patterns of usage and the space available. It regulates the mains frequency to whatever you select – usually 50Hz, and it regulates the selected AC voltage to whatever the equipment requires.
There are two ways to use the system: one is with the charger permanently switched on, and the other is with the charger temporarily switched off. Either way the sonic benefits are comprehensive and once heard, hard to forget. There is also the compound benefit of improved reliability and longevity of audio equipment which likes a stable operating environment – constant voltage, precise frequency conditions, and freedom from mains-borne ‘hash,’ dirt and spikes.
With the charger permanently switched on the battery pack behaves like a large capacitor between the national grid and your system. Used in this way the battery life is expected to be around 20 years.
With the charger switched off the performance improves further. We normally specify a battery capacity that retains 70% of its charge after ten hours of listening ‘off-grid’. Used in this way the battery life is 2500 charge & discharge cycles.
If you wish to electrically separate your digital and analogue electronics, as well as your Class ‘A’ and Class ‘B’ components this is accommodated on the integrated consumer unit and power outlet sockets – something we highly recommend. Interestingly amplifiers that are free from complicated power supply regulating circuits tend to sound more natural, colourful and free – they simply sound more believable. It seems that complicated regulation circuits in amplifiers often create as many problems as they solve. When using the battery power supply system, amplifier regulating circuits become largely redundant because their job has been done for them by having a global AC supply which is stable.
