APPLICATION For driving a balanced 600 ohm line from a desk or distribution amplifier with a high signal level. 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 1:1 or 1:2 or 2:1 voltage ratio. Low dc resistance to minimize insertion loss and output impedance.
RATIO 1+1:2
MAXIMUM LEVEL 0.5 % THD at 50 Hz (40 ohm source, primary windings in series) +34 dBu
DISTORTION at 50 Hz (40 ohm source) 0.1% at +28 dBu
INSERTION LOSS 100 ohm source 1K2 ohm load 0.52 dBu
INPUT/OUTPUT BALANCE >60 dB
DC RESISTANCE Total referred to secondary 65 ohms
FREQUENCY RESPONSE 40 ohm source 1K2 ohm load +/- 0.25 dB 10 Hz to 30 kHz
