The Heritage Audio 2264E compressor limiter is a diode bridge based dynamics module, engineered to be used in the restoration process of vintage 80 Series consoles.

It can also be installed in the Heritage Audio Frame 8 and Rack 2, where there is provision for linking up to 8 units in 2 different buses.

It is fully Class A, including the same output stage found in the HA1073, which reacts in a much nicer way to compression than class A/B amplifiers.

It is completely handmade and wired in the same fashion as the rest of the Heritage Audio 80 Series modules.

Features:

• 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 +26dBu into 600 Ohms,
• 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.
• Noise: Less than -100dBu.
• Power consumption: Less than 110 mA @24VDC.
