| Notes | Electrostatic headspeaker. This is the first Lambda that came in 1978. It had/has a 230 Volt bias, where the later "pro" models (introdused around 1992/93) is driven by 560 Volt in stead. The easiest way to see the difference is that the "normal" 230V models have a six pin connector, where the "pro" models employs a five pin... The pro models can be driven from a "normal" energizer, at redused gain. - While the "normal" headsets cant be plugged in a pro energizer. |
