Impedance
LO Z: Microphone rated impedance is 150 Ω (270 Ω actual)
for connection to microphone inputs rated low impedance
HI Z: Microphone impedance is "High" for connection to
high-impedance microphone inputs
Sensitivity (at 1,000 Hz)
Open Circuit Voltage*
*1 Pascal=94 dB SPL
Phasing
Positive pressure on the diaphragm produces positive
voltage on pin 2 relative to pin 3 in both HI Z and LO Z
modes
Switch
Built-in ON/OFF switch, lockplate to lock switch ON
Connector
Three-pin professional (male XLR) type
Cartridge Shock Mount
Internal rubber vibration-isolator
Swivel Adapter
Positive action, break-resistant, adjustable through 180_,
slip-out removal for handheld use, designed for mounting

IMPEDANCE SELECTION
The microphone is shipped connected for low impedance
operation. To change to high impedance, refer to Figure 4 and
proceed as follows:
1.
Remove plug element by turning slotted setscrew in
(counterclockwise). Use long-nose pliers to pull plug ele-
ment from case, but be careful not to stretch or break
wires.
2.
Disconnect 2-terminal impedance selection socket from
rear of plug element by pulling it off pin 3.
3.
Reconnect impedance selection socket so that pin 3 of
plug element is now connected to RED (high-impedance)
lead.
4.
Swivel socket so that it does not extend beyond edge of
connector (see inset in Figure 4).
5.
Reinsert plug element into microphone; then tighten set-
screw by turning it clockwise.
