EAR 822 Tube Equalizer #01071 (Used)

The EAR 822 EQ Pultec type equaliser has been designed to be highly flexible and thus useful in a wide range of applications. Passive equalisation networks combined with valve input and output buffers are used in order to minimise disturbing side effects such as phase shift and ringing. The audio circuitry conforms to the EAR principles of simplicity and subjective 'transparency', with low distortion at all normal signal levels. A "clickless" bypass switch allows easy comparison between the processed and direct paths. Variations in response include low pass, high pass, band pass and high or low frequency shelf with variable Q and turnover frequency.

• Low boost & cut frequencies - 20, 30, 60, 100Hz; 0, +14, - 18dB variable
• High boost frequencies - 3k, 5k, 7k, 10k, 12kHz; 0, +18dB variable
• Maximum output level (1% distortion) - +25dBm
• Input and output impedance - 600 ohm nominal, balanced and floating
• High cut frequencies - 6k, 10k, 20kHz; shelf 0, - 18dB variable
• Bypass switch - no level change, clickless
• Operation - passive equaliser with balanced tube output
