GRAS 26CC 1/4" CCP Standard Preamplifier with SMB Connector
Freq range: 2.5 Hz - 200 kHz
Noise: 1.8 µV Gain: -0.35 dB
Special feature: General purpose
The GRAS 26CC 1/4" Preamplifier is a general purpose preamplifier optimized for use with prepolarized condenser microphones. It is a small, robust unit and uses a GRAS CCP power supply, e.g. GRAS 12AL. It has a very low inherent noise level, a large dynamic range and a frequency response from below 2 Hz to above 200 kHz.
Technology
Typical applications and use
- CCP inputs
- Plugs into Array Module PR0001(-1)
- Prepolarized microphones
- 1/4" precision microphones
- High levels and high frequencies
Design
The GRAS 26CC 1/4" Preamplifier's small ceramic thick-film substrate has a very high input impedance, and is shielded by a guard ring to minimise the influence of stray capacitance and microphonic interference.
The 26CC is delivered with a built-in TEDS chip, and can be programmed as a single unit with a microphone fitted. It can be used with GRAS 40BE and 40BD ¼-inch prepolarized microphones and 40AE, 40AD and 40AQ ½-inch microphones using the included GRAS GR0010 Adapter for 1/4" preamplifier and 1/2" microphone.
SMB-to-BNC cables in standard and customized lengths are available. The casing is made of stainless steel for maximumstrength and durability.
