APPLICATION For driving a balanced 600 ohm line from a transistor or valve amplifier with an ac coupled cathode follower, SSRP  output.   May be driven balanced or unbalanced. Ideal for building into a distribution amplifier or adding to existing equipment. Provides electrical isolation to minimize most kinds of noise caused when equipments are connected.
FEATURES High grade Grain Oriented Silicon Iron core for high level capability. Internal Electrostatic Screens to ensure optimum output balance. Twin primaries may be connected in series or parallel permitting a 4:1CT or 8:1 voltage ratio.  Low dc resistance to minimize insertion loss and output impedance.
VOLTAGE RATIO 8:1+1
MAXIMUM LEVEL (on 600 ohm winding)    0.5 % THD at 50 Hz  +34 dBu
DISTORTION at 50 Hz (40 ohm source) 0.1% at +28 dBu
INPUT/OUTPUT BALANCE >60 dB
DC RESISTANCE Total referred to secondary 53 ohms
FREQUENCY RESPONSE 1k ohm source 600 ohm load +/- 0.25 dB 10 Hz to 45 kHz
