½" intelligent microphone (SysCheck2™)

What does SysCheck2™ give you:

   •    remote-controlled verification of  the entire measurement chain (detects variation in sensitivity greater than 0.3 dB)

   •    rapidly check all channels with a single click (via TEDS)

   •    remotely monitor environmental data (temperature, humidity and barometric pressure) - detects temperature change greater than 2ºC

   •    no physical interaction with microphones required (remote control via TEDS)

   •    an intelligent microphone with self-test capability

   •    integral RGB LEDs to locate microphones easily

   •    CCP compatible - no need for expensive cabling

½" pre-polarised/CCP*

Type 146AE - ½" free field 'super' rugged!

Freq range: 3.15 Hz to 20 kHz

Dyn range: 18 dB(A) to 133 dB

Sensitivity: 50 mV/Pa

Polarising Voltage: 0 V

Use: 'rugged' acoustic work, automotive

¼" pre-polarised/CCP*

note:  apart from the Type 46BD-S1, all other GRAS ¼" CCP microphone sets come with a female microdot connector, cable not included.

IMPORTANT: ¼" microphone sets are ideally suited for improved accuracy measurement at higher frequencies, with reduced directional effects relative to ½" units

½" externally polarised, LEMO*

¼" externally polarised, LEMO*

IMPORTANT: ¼" microphone sets are ideally suited for improved accuracy measurement at higher frequencies, with reduced directional effects relative to ½" units

⅛" externally polarised, LEMO*

Type 46DP-1 - ⅛" pressure

(integrated connector)

Freq range: 6.5 Hz to 140 kHz

Dyn range: 52 dB(A) to 178 dB

Sensitivity: 0.7 mV/Pa

Polarising Voltage: 200 V

Use: impulse measurement

IMPORTANT NOTES:

    1.  CCP = constant current power, these microphone sets require a constant current power supply to operate correctly

    2.  ½" CCP sets come with a BNC connector, ¼" and ⅛" CCP sets have a microdot connector (apart from Type 46BD-S1 which is SMB)

    3.  all ½" LEMO microphone sets come with an integral 7-pin 1B LEMO connector, a cable is not included

    4.  all ¼" and ⅛" LEMO microphone sets have a 5-pin LEMO connector on preamplifier (cables for 7-pin 1B LEMO available separately)

    5.  GRAS microphone sets (CCP and LEMO) do not include a cable, cables are available separately

    6.  many GRAS microphone sets (CCP and LEMO) include (pressure) capsules that have front vented option and high temp. preamps

    7.  TEDS = Transducer Electronic DataSheet

    8.  we aim to have all information accurate and current, please be aware that 'correct' specifications/details are as per GRAS website
