Endevco® model EM26CB
¼” microphone preamplifier
Typical features / applications

Description

•t Isotron® inputs
•t Prepolarized microphones
•t ¼” precision microphones
•t High levels and high frequencies

The Endevco ¼” preamplifier model EM26CB is a generalpurpose preamplifier optimized for use with prepolarized
condenser microphones. It is a small, robust unit and uses
an Endevco Isotron® power supply, eg. model 4416B. It has
a very low inherent noise level, a large dynamic range and a
frequency response from below 2 Hz to above 200 kHz.
Its small ceramic thick-film substrate has a very high input
impedance and is shielded by a guard ring to minimize the
influence of stray capacitance and microphonic interference.
The model EM26CB is delivered with a built-in TEDS1 chip
and can be programmed as a single unit with a microphone
fitted. It can be used with all Endevco prepolarized
microphones, namely:
t •t ¼” microphones models EM40BE and EM40BD
t •t ½” microphones models EM40AE, EM40AD and
t t EM40AQ, using the included ¼”-to-½” adapter
t •t It has an integrated Microdot output connector.
t t A 10-foot (3 m) Microdot-to-BNC cable is included.
The casing is made of stainless steel for maximum strength
and durability.
