BMU1500 Mk.II Balanced Mains: Russ Andrews

Russ Andrews Accessories’ BMU1500 Balanced Mains Unit provides 1.5kVA of clean power and is individually tailored to each installation

The BMU1500 mkII splits the 230v mains signal into two separate 115v supplies. One is carried on the live and the other on the neutral and as each is a different polarity (negative or positive) the noise on one is cancelled out by the noise on the other.

Where the new BMU1500 mkII differs most from its predecessor, is in the personalised nature of its set up. The electricity supply in the UK by law has to be 230V +10% -6%, giving a minimum of 216.2V and a maximum of 253V, which means the balanced mains unit will not always be working at its optimum efficiency if set to 230v and the user’s domestic voltage differs from this.

Prior to installation of a customer’s BMU1500, Russ Andrews will supply a simple to use, plug in, mains voltage checker. The customer will be asked to measure their house mains voltage over a period of seven days, particularly at the times of day they are most likely to use their hi-fi system and then supply Russ Andrews with the readings. Before shipping the BMU to the customer, the unit will be factory set to the average of the seven days readings. This ensures the BMU will work as efficiently as is possible to provide the maximum audible benefit.

The unit is equipped with a newly-designed balanced mains transformer, “…which is quieter in operation than conventional transformers, to provide the total 1.5kVA of power,” said the company. Russ Andrews UltraSocket mains outlets on the rear enable connection of the hi-fi or home cinema equipment directly to the unit – thereby acting as a mains extension as well as the balanced mains supply. Mains input is via a 16A IEC socket and is protected by use of a two-pole (live and neutral) circuit breakerand the unit is encased in a bespoke ABS case with black anodized front panel. Price is £2,550
