New Products

We have expanded our 3 stage battery chargers from Victron Energy to include a 20 to 60 Amp range. Flooded, gel and AGM batteries can be charged form an input voltage of 90 – 265 Volts. View all our battery chargers.

We have also introduced a range of Victron inverter chargers. These have a huge range of features – too many to even highlight a few here.

Energy Consumption of a Home Theatre Sound System

I have bought myself an early Christmas present – a Sony Blu-Ray DVD Home Theatre System. It has many features including 1000W total output power, 5.1 Surround Sound, and 3D capability. Two of the 6 speakers are operated by a separate wireless surround amplifier rated at 50W according to the compliance label. The main amplifier is rated at 130 watts.

So I was fearing the worst – that my sound system would use more power than my 80cm LCD television (120W).

I am pleased to report that it used substantially less than what the compliance labels read. The wireless surround amplifier used about 2 watts on standby and 9 – 10 watts when operating. The main player/amplifier used 2 – 3 watts on stand-by and between 27 - 30 watts powering the sound from the television (from soft to loud).

When playing a DVD, it used between 27 watts and 60 watts. At 60 watts the sound level was unbearably loud in my small lounge room. All in all, I would suggest that it uses a total of about 40 watts at a normal sound volume.

I am also happy yo say I am very pleased with my new present – a recent magazine review rated the Sony as their first choice based on several factors.

All the best ‘til the new year.

Cheers from Dave and all the RPC crew.
