Description

The Heritage Audio 73EQJR is a fully featured Line Input module for the 500 Series. It not only shares the 3-band equalizer of its big brother, the Heritage Audio 1073, but also shares the same transformer coupled line preamp and Class A transformer balanced output stage.

This makes the 73EQJR unique on its class, being able to capture a full transformer based, Class A sound without relying on external preamps. The EQ features the same Baxandall type High and Low shelf found in the HA1073, with the addition of a high frequency selector switch. 4 different frequencies are possible instead of the fixed 12 kHz one.

The mid band is the same exact dual inductor one, thick low and sweet high midrange boosts without becoming muddy or brittle. The line preamp has a range of +6 to -20 dB, allowing heavy EQ boosts without overloading A/D converters.

Finally, special care has been taken with power handling, implementing internal +24 V slow turn on regulation (about 20 seconds to reach full voltage). This makes your 73EQJR independent of the rest of the slots and makes your lunchbox's PSU happier.

Specifications:

  • Input Impedance: 10 kOhms bridging, transformer balanced and floating
  • Output impedance: Less than 75 Ohms, transformer balanced and floating, to drive a 600 ohms load
  • Maximum output: Greater than +26 dBu into 600 Ohms
  • THD: Less than 0.025% at 1 kHz, less than 0.05% at 100 Hz
  • Maximum gain: 6 dB
  • Power consumption: Less than 85 mA per rail at ±16 VDC
