The Bartlett Bass Mic is a professional quality, miniature microphone
that attaches to a bass f-hole for sound reinforcement. Specially voiced
to sound best on a bass, the mic provides a full, mellow tone. Applica-
tions include old-time, bluegrass, and jazz groups.
A bass tends to sound boomy when miked in an f-hole. The low-frequen-
cy response of the Bass Mic is rolled off to compensate, resulting in a
natural, non-boomy sound.
The Bass Mic has a tiny mic housing with a rugged 8-foot cable
attached to an XLR connector which houses the electronics. The micro-
phone requires phantom power, available from most mixers.
Type: Miniature omnidirectional condenser microphone.
Transducer: Electret condenser.
Frequency response: 40 Hz to 10 kHz. See Figure 1.
Polar pattern: Omnidirectional. See Figure 2.
Impedance: 200 ohms. Recommended load impedance >1000 ohms.
Sensitivity: 26.6 mV/Pa (-32 dBV/Pa). 1 Pa = 94 dB SPL.
Signal-to-noise ratio: >64 dB at 94 dB SPL. Noise is inaudible in
normal use.
Maximum SPL: 134 dB SPL produces 3% THD. The mic will not audi-
bly distort in normal use.
Cable: Permanently attached, 8-foot, black 2-conductor shielded cable
with XLR-type 3-pin connector.
Operating voltage: 18–48V phantom power.
Current draw: 4.5 mA.
Materials: Rugged brass circuit housing/XLR connector.
Finish: Black mic, silver circuit housing/XLR connector.
Net weight: 2.8 oz (79 g).
Dimensions: XLR connector 2.460” long x 0.747” diameter, mic 0.540”
long x 0.325” diameter.

1. Option 1: Plug the mic connector into a mic cable that is connected to
a mixer mic input. That input should supply phantom power.
2. Option 2: Plug the mic connector into a mic cable that is connected to
a phantom power supply. Then connect the phantom supply output to a
mixer mic input.
3. Turn on phantom power before use.
4. The microphone is very sensitive or “hot”. Be sure to turn down the
input gain trim on your mixer as needed to prevent mixer distortion and
feedback.
5. If you also use a pickup, mix the Bass Mic with the pickup to get a
variety of tones.
