Heritage HA73 ELITE
Heritage HA73 ELITE: Single-channel mic / line preamp inspired on the legendary 1073.
- Built with the same specifications as the acclaimed 73JR and DMA73 Heritage Audio models with the best price.
- A combination of mass production, lean manufacturing and modern construction techniques.
- Key components to obtain a true vintage sound
- Includes the same exact great sounding JFET DI circuit found in the 73JR and a fully discrete class A high pass filter.
- Made with standard Carnhill transformers, hand wound in St Ives, England.
- Fully discrete, 3-stage Class A mic preamp with 80dB of gain
- Microphone input impedance:
- HI, 1200 Ohm minimum,
- LO, 300 Ohm minimum.
- Higher gain positions gradually have greater impedances
- Optimum for low gain ribbon mics.
- Input is transformer balanced and floating.
- Line input impedance: 10KOhms bridging, transformer balanced and floating.
- Output impedance: Less than 75 Ohms, transformer balanced and floating, to drive a load of 600 Ohms.
- Maximum output: Greater than +26.5dBu into 600 Ohms (internally terminated)
- THD: Less than 0.025% at 1Khz, Less than 0.05% at 100Hz.
- Frequency response :20Hz (+0.3dB) to 20Khz (-0.2dB).
