1073/500 FEATURES1073/500 SPECIFICATIONS

• 70dB Class A Microphone preamplier, HI-LO

selectable minimum input impedance, balanced and

oating. High gain positions show a higher impedance,

ideal for old ribbon mics.

• 10dB Class A Line Amplier, Bridging input

impedance, balanced and oating.

• Class A, single ended, 2N3055 driven high headroom

output stage.

• High Frequency: +/-16dB shelving at 12 kHz,

Baxandall type.

• Low Frequency: +/-16dB with selectable frequency

shelving of 35Hz, 60Hz, 110Hz & 220Hz ,Baxandall

type.

• Mid Frequency: +/-18dB peaking, xed ‘Q’ , selectable

center frequencies of 0.36kHz, 0.7kHz, 1.6kHz, 3.2kHz,

4.8kHz , and 7.2kHz , dual inductor based.

• High Pass Filter: 18dB per octave slope, switchable

between 50Hz, 80Hz , 160 Hz & 300Hz, inductor

based.

• EQ Button: Switches the equalizer on or off.

• Phase Button: Flips phase 180º.

• 1073 Module available. 19” Convertible format

available Winter 2012.

• Microphone input impedance: HI, 1200 Ohm

minimum, LO, 300 Ohm minimum. Higher gain

positions gradually have greater impedances, optimum

for lo gain ribbon mics. Input is transformer balanced

and oating.

balanced and oating.

• Output impedance: Less than 75 Ohms, transformer

balanced and oating, to drive a load of 600 Ohms.

• Maximum output: Greater than +26dBm into 600

Ohms, greater than +32dBu into 10KOhms.

• 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 -100dBm.

• Power consumption: 78 mA per rail @+-16VDC.
