Vibraphone® – ASB8

Vibraphone® – ASB8
Electronic P listening equipment: Geo-stereophone
The ASB8 Vibraphone®, known by rescue teams all over the world, enables to
detect a victim buried under rubble after a catastrophe and to locate him precisely.
The slightest noise the victim makes can be detected by this device, whose
sensitivity is exceptional.
The Vibraphone® is fitted with an adjustable filter which deadens the effect of dull
noises like pneumatic drills, trucks passing, etc.
The national reference guide specifies that at least two electronic listening packs
should be carried in vehicles or with ‘rescue / clearance’ teams.
Specifications:
• Operating temperature : - 10°C to + 60°C
• Storage temperature : - 25°C to + 70°C
• Total weight : 2 kg (in use)
7.9 kg (with carrying case)

Vibraphone® – ASB8
Components:
• 1 IP66 housing with bar-graph for adjustment
• 2 very high gain, low noise amplifiers
• 2 frequency filters ‘ high pass and band pass’ infinitely variable, filters
activated by F1 or F2 key (the chosen frequency is infinitely variable
using the + and - keys) :
- Filter 1: ‘High pass’ filter, significantly reduces all frequencies
below its adjustment point, which may be between 50Hz and
5 kHz which correspond respectively to the low and the high
points of the scale. It eliminates bass sounds such as lorry
movements, dull noises, etc.
- Filter 2: ‘Band pass filter’ significantly reduces low and high
frequencies on either side of its tuning point. It filters an
incoming signal.
• 2 ultra-high sensitivity vibration sensors with 8m of cable with
20% more sensitivity than the previous version
• 1 sound sensor incorporating a microphone and a loud speaker, with
8m of cable
• 1 stereo head-set with microphone
• 1 pack of 6 rechargeable Ni/Mh batteries type LR6 / AA
(operating life 30h)
• 1 accumulator charger (usable at 50/60Hz 100v to 240v)
• 1 cigarette lighter charger plug with wire for use in a vehicle
• 1 carrying cordura housing with strap
Important:
• 1 shock-proof carrying case, dimensions L475 x D415 x H215mm
Each time you start using the Vibraphone®, it is necessary to adjust the operating threshold.
In order to do this, increase the gain progressively, leaving the two contacts on the ground until noises produce
a reaction from the sensors, then decrease the gain one level on the scale.
The operating threshold is now defined.
