| When running a recording with an HMS III, HMS IV or a BEQ II while synchronously online monitoring the recording, there might occur strong overloads during a range shift (reduction of the recording range). |
| The occurring overloads injure the sense of hearing seriously. |
Using the current firmware for the afore-mentioned recording devices prevents overloads during the range shift by means of a delayed fading.
We strongly recommend all our customers to keep all existing HMS III, HMS IV and BEQ II recording systems updated to the latest firmware and thus to protect yourself from a possible danger and to benefit from the continuing improvements of the products. |
The firmware can be downloaded from the download area of our website:

Binaural, digital equalizer with
24 bit technology and USB interface |
|
|
The digital equalizer BEQ II.1 combines
the characteristics of an equalizer, a two-channel
front end and an A/D converter into one mobile and
very versatile measurement tool. |
|
|
Binaural, aurally-accurate recordings
can be conducted easily with BEQ II. The AES/EBU
interface allows a quick and easy expansion into
a four-channel system, e.g. with the HMS III or
HMS
IV. Via the ADAT interface, up to four BEQ II
units can be connected, allowing for eight-channel
recordings. |
|
|
Integrated signal conditioning allows
common measurement sensors (Microphone, Line, ICP®)
to be directly connected to the front end. In addition,
separate pulse inputs are available e.g. for RPM
data acquisition. |
|
|
Thanks to the high-performance built-in
battery - external DC power supply is also possible
- and its low weight, BEQ II.1 is the ideal tool
for either mobile or stationary operation. |
