Bruel & Kjaer ZG0350 Highlights
You can use a dual (plus/minus) or single power supply for the preamplifier. When using a balanced power supply, the offset voltage at the output – and at the preamplifier guard ring – will be almost zero. This protects you against electric shocks when you mount or remove the microphone, and gives a faster stabilisation time for a measurement setup. You can use the preamplifier with traditional power supplies with Brüel & Kj_r sockets by means of Adaptor ZG 0350.
