Audionics 3000 Series Line Amplifiers

The 3000 series line amplifiers are designed to interface land lines with studio equipment, providing galvanic isolation, impedance and level conversion. Both amplifiers are 160mm Eurocards and can be mounted in a 1U, 19" rackmount case or a standard 3U card frame.

3150 Line Receiver

The 3150 line receiver has one transformer isolated input with DC protection and four low impedance transformer isolated outputs designed to feed bridging loads. The input impedance matches a 600ohm land line and gain adjustment of ±6dB is available. This card can be additionally used as a transformer isolated distribution amplifier by removal of the input load resistor. Audio inputs, outputs and power are via a 32 way DIN 41612 connector. The card requires a dual rail ±15V to ±18V power supply.

3154 Line Driver

The 3154 line driver has a high impedance electronically balanced input and a transformer isolated output to drive a 600 ohm land line. The level trim will give ±6dB of gain adjustment and there is an additional preset to adjust output balance. Audio input, outputs and power are via a 32 way DIN 41612 connector. The card requires a dual rail ±15V to ±18V power supply.

3000 Series Rack Case

A 1U, 19" rackmount case with integral power supply. This will accept two line amplifier cards. Line drivers and receivers can be mixed within one unit. Audio inputs and outputs are via a rear panel mounted 56 way Varicon connector.

Pre Assembled Systems

A maximum of twelve line amplifiers can be supplied pre-wired in a 3U, 19" rackmount card frame with integral modular power supply. All audio inputs and outputs are wired to rear panel mounted 56 way Varicon connectors
