TOA ER-1000A-BK Personal PA System


The ER-1000A-BK is a compact, lightweight, hands-free portable public address system with a rated power output of 6 W (9 V DC when used with six AA-type batteries). The system can be wrapped snugly around the waist and using the supplied headset microphone allows both hands to remain free, making it ideal for such applications as conducting factory tours, directing traffic, instructing in sports facilities, and security-and-safety-related applications.


Power Source :

  • Alkaline battery (LR6): 6 pieces (9 V DC) or 4 pieces(*1) (6 V DC)
  • Rechargeable nickel metal hydride (Ni-MH) battery (HR15/51): 6 pieces (7.2 V DC) or
  • 4 pieces(*1) (4.8 V DC)

Output :

  • 6 W (rated) and 10 W (max) when 6 AA batteries (9 V DC) are used.
  • 3 W (rated) and 4 W (max) when 4 AA batteries(*1) (6 V DC) are used.

Battery Life :

  • Voice operation (*3): Approx. 8 hours (when 6 or 4(*1) alkaline batteries are used)
  • Approx. 7 hours (when 6 or 4(*1) Ni-MH batteries are used)
  • AUX stereo input operation (music reproduction)(*4):
  • Approx. 9 hours (when 6 or 4(*1) alkaline batteries are used)
  • Approx. 9 hours (when 6 or 4(*1) Ni-MH batteries are used)

Audible Range(*2) :

  • Voice operation: Approx. 100 m (when 6 alkaline batteries or Ni-MH batteries are used)
  • Approx. 80 m (when 4(*1) alkaline batteries or Ni-MH batteries are used)

Frequency Response : 300 Hz – 14 kHz (deviation: -26 dB)

Headset Microphone :

  • Ear-on type, electret condenser microphone,
  • sensitivity: -47 dB (0 dB =1 V/1 Pa, 1 kHz)

(*1) when the supplied battery spacers are used.
(*2) Audible range is measured on a quiet street with the Personal PA System loaded with fresh batteries
Range varies depending on surrounding environmental conditions, such as battery consumption, ambient noise levels, wind direction and obstacles. Reference standard: JEITA (Japan Electronics and Information Technology Industrial Association) TT-4501D
(*3) Battery life during voice output usage represents the period of time when the Personal PA System is continuously used with the volume control set to a position that does not cause feedback. Reference standard: JEITA TT-4501D
(*4) Battery life during AUX stereo input represents a value actually measures when music is continuously reproduced with a commerical audio player connected to the AUX input terminal. It varies depending on the connected external equipment’s volume output or the type of music source.
(*5) 0 dB = 1V
(*6) Adjust the volume or the AUX input at the connected external device.
(*7) Volume during monaural operation is smaller than during stereo operation.
(*8) The 120cm length is when the Belt is stretched out to its maximum extent. When worn, consider a Belt length of 100cm (of waist size when clothes are worn) as a rule-of-thumb standard.

Note: Prepare batteries separately, as they are not supplied with the product.
