e60

The Equitek e60 combines a
condenser capsule design
with advanced electronics.
Typical FET (field effect tran­sistor) condenser micro­phones use discrete de­signs. This means they use
individual transistors that
must be carefully matched
for proper characteristics.
Even with careful matching,
discrete designs are inher­ently nonlinear. Equitek mi­crophones use a different
approach. We do not use
any discrete FETs. Instead,
we use advanced high speed
OpAmps (Operational Am­plifiers). These OpAmps are
individually laser trimmed
for optimum performance
and have very high gain.
This allows a large amount
of negative feedback to be
used to significantly reduce
any non-linearity. In the
past, these OpAmps re­quired more current than
typical phantom power sup­plies can deliver. Some of
our equitek series micro­phones use rechargeable
batteries to compensate for
this heavy power consump­tion, but with advances in
technologies, and extensive
research and development,
CAD has eliminated the need
for the extra batteries. This
allows us to use the same
classic Equitek technology
in a smaller package. The
end result, the e60, a multi
purpose, true condenser mi­crophone featuring all the
benefits of our earlier
equitek microphones yet fit­ting in the palm of your hand!

Description

The Equitek e60 from CAD is an externally biased cardioid condenser microphone.

The Equitek e60 incorporates a number of unique features including:

•16mm, 24k Gold sputtered externally biased condenser capsule.

•10dB non-capacitive pad

•4 position hi-pass filter - flat, 40Hz, 85Hz, and 122Hz

•CAD's proprietary discrete linear power supply for efficient low noise and linear power
regulation, allows greater dynamic range and lower equivalent self-noise

Getting Started

The e60 requires 24-48 volt phantom power for proper operation. Before plugging the
microphone in, make sure the selected channel is turned off.

NOTE: If the microphone is plugged into a hot channel, this will result in a loud “pop”
which can possibly damage your audio equipment.

Next, plug the male end of a standard 3 pin mic cable into a mixing console equipped
with phantom power, then plug the female end of the cable into the microphone.

Make sure all of the gains are turned down, and the pad switch is in the -10 position.

Finally, turn on the channel which the microphone is plugged into, and turn on phantom
power if applicable.

Caution!

Before using the microphone, the circuit needs to stabilize for a period of 2-3 minutes.
Do not switch any of the switches on the back of the e60 until after the initial
stabilization time mentioned above. Failure to do so will result in a “pop” similar to
plugging the mic into a hot circuit, again this could possibly damage expensive audio
gear if done repeatedly.

User T echniques and Applications

The e60 is equipped with a standard 5/8x27 threaded swivel adaptor which fits most microphone stands. Adaptors are widely
available in order to make the e60 fit smaller thread mic stands. The e60 is designed specifically for use as an instrument
microphone for overheads, hi-hats and pianos. The e60 is great for virtually all acoustic, wind, and amplified instruments. One
of the most popular uses for the e60 is in miking drum sets, ideally in an overhead type configuration. The e60 also excels at
miking stringed instruments such as acoustic guitars. The e60 has a four position roll-off which allows for extended “tuning”
of the frequency response at the microphone for your particular application. (See the frequency response chart for more details).
The e60 is also equipped with a -10dB pad switch to reduce the output level of the microphone by 10dB accordingly. If your
board is “clipping” or distorting when using the e60, try switching the pad switch to the -10dB position. Alternatively, if
your are not getting enough signal from the microphone, switch the pad switch to the 0dB position.

The e60 microphone uses a true condenser microphone element. As with any studio condenser microphone, special care should be
taken to keep the microphone clean and dry. It is highly recommended the e60 be stored in its included vinyl pouch in a cool,
dry environment to ensure long life of the capsule when not in use. If the e60 is used in a vocal application, it is very
important to use a fabric “pop” filter such as a CAD EPF-15A positioned between the user and the microphone. Pop filters do
not adversely effect the performance of the microphone in any way.
