SYSTEM COMPONENTS
F-101 C/F-101 CM
F-121 C/F-121 CM
High Ceiling Speaker
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.
Ceiling Speaker is equipped with a specially designed
sound diffuser, housed in a mesh cone, and uses the AC120 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 installations in public spaces, restaurants, offices, or shopping
malls while requiring fewer units.

APPEARANCE AND DIMENSIONAL DIAGRAM
*F-101C and F-121C transformer not included
F-101C/F-101 CM POLAR RESPONSE
OVERLOAD PROTECTION
To prevent damage from excessive low frequencies, the
F101C has a built-in overload protection circuit. During operation, 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 approximately 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
18,000Hz (-10dB).
Power handling capacity for the F-101C 8Ω impedance unit
shall be 40W continuous pink noise or 120W continuous program.
The F-101 C/F-101 CM shall have 5 transformer taps. The taps
shall be 20W, 10W, 5W, 3W and 1W. The F-101C also shall
have a built-in protective circuit that prevents low-mid frequency overload by reducing only the low-mid frequency signals.
The enclosure shall be a tuned, ported, bass-reflex type molded 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, respectively. It shall include a 24" safety cable with spring clip for
easy anchoring to support structure. It shall also accommodate separately supplied T-bars and is sized to fit inside an
appropriate metal back can, if desired.
The finish shall consist of an off-white front grille. Front grille
dimensions shall be 10.24" outer diameter. The ceiling hole
shall be 8.58" in diameter.
Required ceiling space shall be at least 6.30" in height, and
ceiling tile thickness shall range from .02"-1.4".
The assembly’s weight shall not be more than 5.5 Ibs. for the
F-101C and 6.2 Ibs. for the F-101CM with a transformer.
