LINE MATCHING TRANSFORMERS

Atlas/Soundolier Models T-10, T-11, T-20 and T-18 are line matching U-frame, varnish-impregnated transformers. High efficiency units reduce line loss when long transmission cables interconnect amplifier and loudspeakers and when two or more loudspeakers are connected to a common amplifier source. Each unit features element-resistant components and clearly identified terminals for solder connection. Model T-11 features a unique external "power reminder" indicator to reference the setting in use and includes a weatherproof metal housing with baked epoxy finish. All models offer a wide selection of primary and secondary impedance and power taps. See charts below for model specifications and dimensions.
