Heritage Audio HA-73 Elite

The HA-73 Elite mono channel microphone preamp is made to the same specifications as the acclaimed 73 JR II and DMA 73 Heritage Audio models at a price never heard before.
Leveraging the expertise and reputation obtained with its popular hand wired, extremely time-consuming hand soldered series, HA is able to offer a zero compromise, high quality yet very affordable alternative to the growing entry-level brands.
A combination of mass production, lean manufacturing and modern construction techniques, minimizes hand labor and therefore its high associated costs when manufacturing takes place in Western Europe. By passing the savings straight into the end users´ pockets, Heritage Audio releases the most affordable outboard preamps and equalizers in its class up to date.

• Microphone input impedance: HI=1200 Ω minimum, LO=300 Ω minimum. Higher gain positions gradually have greater impedances, optimum for low gain ribbon mics. Input is transformer balanced and floating.
• Line input impedance: 10 kΩ bridging, transformer balanced and floating.
• Output impedance: Less than 75 Ω, transformer balanced and floating, to drive a load of 600 Ω.
• Maximum output: Greater than +26.5 dBu into 600 Ω (internally terminated).
• THD: Less than 0.025 % at 1 kHz, Less than 0.05 % at 100 Hz.
• Frequency response: 20 Hz (+0.3 dB) to 20 kHz (-0.2 dB).
• Maximum Gain: Slightly greater than 80 dB.
• Equivalent Input Noise: Less than -125 dBu.
• Output stage noise: Less than -100 dBu.
• Power consumption: Less than 95 mA @48 V DC.
