Campbell Associates supply a full range of preamplifiers which are small and robust and optimised for your acoustic measurements. They are the highest quality and supplied with a two year warranty.

Type 26CA Pre-polarised Microphones

A 1/2" preamplifier for connection to CCP1 input channels , e.g. see Type 12AL. The Type 26CA has a standard BNC output connector and is for use with pre-polarised microphones.

Type 26AK General Purpose

General-purpose preamplifier with an integrated 7-pin LEMO connector. A 3m cable AA0008 (not included) is available with 7-pin to 7-pin LEMO connectors. Other lengths are available on request.

Type 26AA Intensity Measurements

Preamplifier with 30 cm lightweight cable terminating in a 4-pin LEMO 0B connector.

Code Description
Type 26AC General Purpose
General-purpose preamplifier with an integrated 3m,lightweight cable terminating in a 7-pin LEMO connector.,A 1/4" to 1/2" adapter, GR0010, is included, so that it can also be used with 1/2" microphones.
Type 26AL Built-in SysCheck
General-purpose preamplifier with an integrated 3m,lightweight cable,terminating in a 7-pin LEMO connector.,Includes built-in SysCheck facility for enabling,easy system checks to be made. A 1/4" to 1/2" adapter, GR0010, is,included,,so that it can also be used with 1/2" microphones.
Type 26HG Intra-sound
Similar to Type 26AC but with 40 GOhm input,impedance to enable low-level noise measurements at very low frequencies,(infra-sound).
Type 26AB General Purpose
General-purpose preamplifier with an integrated,7-pin LEMO connector. A 1/4" to 1/2" adapter, AF0008, is included, so,that it can,also be used with 1/2",microphones. Cable not,included.
Type 26AN Insert-voltage
Preamplifier with an integrated 7-pin LEMO,connector. Configured to permit use of the insert-voltage technique for,determining,the open-circuit sensitivity of a microphone. A 1/4",to 1/2" adapter, GR0010, is included, so that it can also be used with,1/2" microphones. Cable not included.
Type 26TC Built-in TEDS
Preamplifier with an integrated 3m,lightweight,cable terminating in a 7-pin LEMO connector. Includes built-in TEDS,chip which enables it to be programmed with,calibration data as a complete unit together with a microphone. A 1/4",to 1/2",adapter, GR0010, is included, so that it can also be,used with 1/2" microphones.
Type 26AS/AR Small Dimensions
It is a small robust unit short enough for use in,confined spaces, e.g. for binaural measurements with the KEMAR Manikin,Type 45BA or the Hearing-protector Test Fixture Type,45CA
Type 26CC CCP Type Preamplifier
Similar to the Type 26CB but with an integrated SMB connector which allows it to be used directly on,Array Modules PR0001 and PR0002.
Type 26CG CCP Type Intra-Sound (for Microphone type 40AZ)
The CCP1 Type 26CG has been designed for,measurements at very low frequencies (infra-sound), below 1 Hz. It has a,very,wide bandwidth (from below 1 Hz to above 200 kHz),and a low inherent noise level, owing to the 40Gohm input impedance, and is thus applicable for use at very low sound,pressure levels. Used with 1/2" Free-field Microphone Type 40AZ, Infra-sound.
Type 26CS CCP Type Preamplifier
Type 26CS is a very small preamplifer. The 26CS is,integrated with a Microdot connector and is delivered with a 3 m,Microdot-BNC cable for direct connection to CCP1,input channels with a standard BNC socket, e.g. see Type 12AL.
Type 26CB CCP Type Preamplifier
A 1/4" preamplifier for use with prepolarised,microphones such as those listed below. The 26CB is integrated with a,Microdot connector and is delivered with a 3m,Microdot-BNC cable for direct connection to CCP1 input channels,with a standard BNC socket, e.g. see Type 12AL. The,built-in TEDS2 chip enables it to be programmed as a complete unit,together with a microphone.
Type 26AJ General Purpose
General-purpose preamplifier with an integrated,7-pin LEMO connector. A 3m cable AA0008 (not included) is available,with 7-pin to 7-pin LEMO connectors. Other lengths,are available on request.
Type 26AM General Purpose
General-purpose preamplifier with an integrated 3m,cable terminating in a 7-pin LEMO connector.
Type 26AH General Purpose
General-purpose preamplifier with an integrated 3m,cable terminating in a 7-pin LEMO connector. Includes SysCheck,facility for enabling easy system checks to be made.
Type 26AG General Purpose
Preamplifier with an integrated 7-pin LEMO,connector. Configured for use with the insert-voltage technique for,determining,the open-circuit sensitivity of,a microphone,cartridge. A 3m cable AA0008 (not included) is available with 7-pin to,7-pin,LEMO connectors. Other lengths are available on,request.
Type 26TK General Purpose
Preamplifier with an integrated 7-pin LEMO,connector. Includes built-in TEDS chip which enables it to be programmed,with,calibration data as a complete unit with a,microphone cartridge. A 3m cable AA0008 (not included) is available with,7-pin,to 7-pin LEMO connectors. Other lengths are,available on request.
Type 26CF General Purpose
Is for connection to CCP1 input channels, e.g. see,Type 12AL. It has a standard BNC output connector and is for use,with prepolarised microphones. It is delivered,without a cable. It also has two flush-mounted switches for selecting,various,combinations of gain (0 and +20dB) and filtering,(A-Weighting, Linear, High-pass).
