Owner’s Manual
ARCHITECT SPECIFICATIONS
The headset microphone shall be a pre-polarized condenser type with an omni-
directional polar pattern. The microphone diameter shall be 5.4 mm (0.21 in).
The frequency response shall be 20 Hz to 20 kHz with an effective frequency
range within ±2 dB from 40 Hz to 20 kHz and with a 3 dB soft boost at 8 – 20
kHz. The sensitivity shall be 6 mV/Pa (-44 dB re. 1V/Pa) at 1 kHz within a
tolerance of ±3 dB. The equivalent noise level shall be 26 dB(A). The
microphone shall not exceed 1% THD at 137 dB SPL peak. The microphone shall
have a dynamic range of 111 dB. The Max. SPL (10 % THD) shall be 144 dB SPL
peak. The rated output impedance shall be 30 – 40 Ω and the connector type
shall be LEMO 3-pin. The cable length shall be 1.2 m with a cable diameter of
1.6 mm and in brown color. The microphone boom and detachable cap shall be
brown inclusive the stainless-steel grid of the cap. The microphone shall be
protected against water and dust to an IP58 rating. The operating temperature
shall range from -40°C to 45°C (-40°F to 113°F) and the microphone shall
function in humidity levels up to 90%. The polarity of the signal on pin 3
shall be positive going for a positively increasing sound pressure.
The microphone shall be the DPA 4066 Omnidirectional Microphone type
