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.

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.

The F-121 C/F-121 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-121C/F-121CM 8 shall be 40W continuous pink noise or 120W continuous program. The transformer taps on the F-121 C/F-121 CM shall be 20W, 10W, 5W ,3W and 1W. The F-121C 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 mold-
ed from a flame-resistant polymer. It shall incorporate four 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 be sized to accommodated mounting
