Heritage Audio 73 Elite - '73 Mic Preamp and DI

The Heritage Audio '73 Elite Elite is an 1073 style pre-amp and DI. The unit includes components found in the original units such as Carnhill transformers enabling the unit to emulate the original 'vintage sound'. The unit also contains the exact same JFET DI circuit found in the HA-'73Jr. With 80dB of available gain, with dedicated mic, line and DI inputs available, the HA73 Elite has everything needed to bring instruments and microphones to life with a classic sound.

Specifications

• 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).
• Maximum Gain: Slightly greater than 80dB.
• Equivalent Input Noise: Less than -125dBu.
• Output stage noise: Less than -100dBu.
• Power consumption: Less than 95 mA @48VDC.
