1.1 Product Info and Compatibility
The EPS2116 is a necessary accessory that provides complete protection for
your ½-inch microphone and preamplifier against wind, rain, snow, humidity,
and physical damage.
In high humidity environments, the optional desiccant cartridges preserve the
performance of your environmentally certified preamp/mic (See Table 1.1 for
environmentally certified models). It is especially effective for back-vented
microphones. It this scenario, moist air is absorbed by the desiccant before
reaching the preamplifier and the back of the microphone. Additionally, the
built-in birdspike effectively deters birds from perching on the device.
The EPS2116 is intended to be connected on a threaded ¾-inch conduit, or a
1½-inch (38mm) speaker stand, or fastened on a mounting screw and applied to
a tripod in the field.
When used with an environmentally certified preamplifier, the EPS2116 protects
your microphone and preamplifier from the environment. However, it is only
effective if the preamplifier in use has a waterproofing o-ring installed.
Refer Table 1.1 to ensure your device is ready for use with the EPS2116.
Table 1.1 Larson Davis Preamplifiers and Compatibility
Environmental Certification service for your qualifying preamp is available by
contacting your Larson Davis representative.

1.2 Assembling the EPS2116
Complete each step in this section in the order it’s presented. Once assembled, the
EPS2116 can be left in place during calibration or transport.
The EPS2116 is shipped with the base and adapter in one assembly. The top cap,
windscreen, and birdspike are combined in a second assembly, as shown in Figure 1-1.
FIGURE 1-1 EPS2116 As shipped
Step 1. Follow the steps associated with Figure 1-2 to prepare the EPS2116 for use.
FIGURE 1-2 Overview of EPS2116 assembly
CAUTION DO NOT pull the
windscreen (W) upward over the
birdspike (BS).
If you need to separate the
birdspike (BS) and windscreen (W),
be sure to pull the windscreen
down and the birdspike up.

Step 2. Thread the included cable upward through the mounting adapter (MA) and
base (B) as shown in Figure 1-2, step 2.
When using the PRM831 preamplifier, complete Installing Desiccant
Cartridges (steps a–c). Alternatively, if you are using the PRM2103, desiccant is
not required. Instead, refer to the SoundAdvisor 831C Manual, section 9.13 to
choose preamp heater options.
Installing Desiccant Cartridges
a. Insert five desiccant cartridges into four of the desiccant chambers in the base.
b. Insert desiccant indicator (clear tube) into the fifth chamber.
FIGURE 1-3 Inserting desiccant indicator
TAKE NOTE When the desiccant indicator crystals change color, replace the
cartridges. Replacement cartridges are available to order from LarsonDavis.com (Part
#DSC003)
Step 3. Connect the preamplifier to the cable. (See Figure 1-4)
Step 4. Slide the preamplifier partially through the top cap, and then screw the top cap
to the base.
TAKE NOTE You should expect some resistance pushing the preamplifier partially
through the top, especially for preamplifiers with a built in o-ring.

Step 5. Screw the 1/2-inch microphone onto the preamplifier, and then carefully push
the preamplifier back down into the top cap until it stops and the microphone
is seated properly in the EPS2116. If your model includes a weatherproofing O-
ring, install over the preamp before screwing the microphoneas shown in
Figure 1-5.
FIGURE 1-5 Installinga weatherproofing O-ring
Step 6. Screw the birdspike (with attached rainscreen) onto the top cap.
Step 7. If the windscreen is not already in place, slide it over the birdspike until the
bottom of the windscreen is seated on the EPS2116 top.
CAUTION If you need to remove the windscreen, do not pull it off the birdspike with an
upward motion. First, unscrew the birdspike by twisting the top, then pull the
windscreen down over the bottom of the unscrewed birdspike.
1.3 Calibrating a Microphone in the EPS2116
You may calibrate a microphone without removing it from the EPS2116 as shown in this
section.

step 1. step 2. step 3. step 4. 5.
Step 1. Remove windscreen/birdspike by unscrewing the windscreen/birdspike
assembly from the top cap.
Step 2. Place the calibrator (CAL 200 shown) on the microphone by gently pushing
down while twisting slightly clockwise.
TAKE NOTE If needed, pull the mic/preamp upward out of the top cap, so the
microphone seats fully inside the calibrator.
Step 3. Calibrate the microphone as described in the microphone manual. When the
calibration is complete, remove calibrator by pulling up and slightly twisting
counter-clockwise.
Step 4. Replace the windscreen/birdspike assembly.
