SYSTEM COMPONENTS
F-101 C/F-101 CM
High Ceiling Speaker
F-121 C/F-121 CM
Uniform Directivity Ceiling Speaker
AC-120 Dedicated Equalizer
DESCRIPTION
Two new speaker systems from TOA provide extensive
sound coverage for a variety of sound applications.
The F-101C/F-101 CM High Ceiling Speaker is designed to
provide full-range sound in areas with high ceilings at a low
cost.
The F-121 C/F-121 CM Uniform Directivity Ceiling Speaker
System is designed to provide a much wider dispersion
angle than standard ceiling speakers. Conventional 4" or 8"
ceiling mounted speakers have a severe sound quality and
intelligibility drop off outside the area directly underneath
the speaker. The F-121 C/F-121 CM Uniform Directivity
Ceiling Speaker is equipped with a specially designed
sound diffuser, housed in a mesh cone, and uses the AC-
120 Dedicated Equalizer that ensures optimal frequency
response. The F-121CM is transformer equipped with mul-
tiple line taps for loudness selection. This speaker provides
higher sound quality for low ceiling mounted speaker instal-
lations in public spaces, restaurants, offices, or shopping
malls while requiring fewer units.

OVERLOAD PROTECTION
To prevent damage from excessive low frequencies, the
F101C has a built-in overload protection circuit. During oper-
ation, if the overload circuit senses excessive low frequency,
it will attenuate the low frequency output of the speaker.
Once activated, the protection circuit will reset in approxi-
mately 10 seconds after turning the system volume down to
prevent reoccurrence.
ARCHITECT’S AND ENGINEER’S
SPECIFICATIONS
The speaker shall be the compactly designed TOA bass-reflex
full-range ceiling mount speaker, the F1O1C at 8 ohms low
impedance/F-101 CM with 70V/100V high impedance line
transformer. The speaker shall provide smooth frequency
response and high power handling capacity.
The F-101C/F-101 CM shall have a ceiling mount assembly
incorporating a 4.7" full-range speaker. Sensitivity shall be
90dB (1W, 1m) with a frequency response of 80Hz to

quency overload by reducing only the low-mid frequency sig-
nals.
The enclosure shall be a tuned, ported, bass-reflex type mold-
ed from a flame-resistant polymer. It shall incorporate four
spring swing arms and two spring-loaded clips to facilitate
easy installation of both the enclosure and front grille, respec-
tively. It shall include a 24" safety cable with spring clip for
