Heritage Audio 2264E

The Heritage Audio 2264E compressor limiter is a diode bridge based dynamics module, engineered to be used in 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.

• Gain Reduction meter: Shows the compression amount up to 20 dB
• Limit switch: Enables limit function
• Compress switch: Enables compression and gain makeup functions
• Limit recovery switch: Switches between 6 time constant options; 50ms, 100ms, 200ms, 800ms, Auto1 (100ms on peaks, 2secs on program material) and Auto2 ( 50ms on peaks, 5secs on program)
• Limit Level Stepped control: Sets the level at what limit begins, from +15 dBm down to +4 dBm in 0.5 dB steps)
• Compress recovery switch: Switches between 6 time constant options; 100ms, 400ms, 800ms, 1500ms, Auto1 (100ms on peaks, 2secs on program material) and Auto2 (50ms on peaks, 5secs on program)
• Compress Threshold Stepped control: Sets the minimum level at what compression happens, from +10 dBm down to -20 dBm in 2 dB steps)
• Compress Ratio Switch: Allows the user to choose between 5 different compression ratios, 1.5" 2, 3, 4and 6:1
• Gain Makeup Stepped control: In 2 dB steps from 0 to 20 dB
• Bypass switch: Switches the module in/out of the signal path
• IND switch: Allows the module to be linked to Buss A, Buss B, or independen.

• Line input impedance: 10 kOhms 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 dBm into 600 Ohms, greater than
• +32dBu into 10 kOhms
• THD: Less than 0.025% at 1 khz, less than 0.05% at 100 Hz
• Frequency response: 20 Hz (+0.3dB) to 20 khz (-0.2 dB)
• Maximum Gain: 20 dB
• Noise: Less than -90 dBm when gain makeup set to 0 dB
• Power consumption: 112 mA @24 VDC
