The properties of the HMS IV.1 allow for high flexibility for aurally accurate binaural recordings. Recordings can be saved directly to a CompactFlash card, which is installed in an easily accessible slot located on the front of the HMS IV.1. Aurally accurate playback directly from the CompactFlash card via a headphone, such as the dynamic headphones HD IV.1 or HD IV.2, is possible thanks to the addition of an integrated headphone output. With the RC VI remote control system, consisting of a Bluetooth® adapter and a PDA, all functions of the HMS IV.1 can now be controlled remotely. Furthermore, the HMS IV.1 is prepared for mounting various additional equipment, such as the laser pointer TLP. Extension Options ·· HEADRecorder software (via note book/PC) ·· High-end headphones 12.2014 D1501e8 Subject to change The HMS IV.1 can be connected directly to the controller module of a HEADlab system. With the HSM V seat mount adapter, the entire hardware can be safely mounted in a car. Features CompactFlash Recordings can be saved directly to a Compact Flash card and played back from the card. The CF slot in the front side of the shoulder unit is easily accessible, so the card can be easily replaced. Wireless Remote Control RC VI All functions of the HMS IV.1 can be remotely controlled with the RC VI system, consisting of a PDA (Personal Digital Assistant) and a Bluetooth® adapter attached directly to the HMS IV.1. The RC VI has a range of about up to 10 meters (30 ft). Triaxial Laser Pointer TLP In order to position the HMS IV exactly and repro ducibly, the TLP can be mounted easily on the top mounting platform of the artificial head. With its three laser beams, the position and orientation of the HMS IV.1 can then be adjusted exactly. Playback Via the headphone output on the back side of the HMS IV.1, a direct playback of audio signals for monitoring or playback from the CompactFlash card is possible, e.g. with the optional dynamic headphones HD IV.1 or HD IV.2. USB Interface Alternatively, recordings can be saved directly to a notebook or PC via the USB 2.0 interface. Analog Output With its analog output, the artificial head can also be operated in combination with analog measurement systems. Since the analog output signal is generated from the digital signal, the advantages of the digital signal equalization are maintained. 12.2014 D1501e8 Subject to change Pulse Inputs The HMS IV.1 electronics allows RPM pulses to be recorded on to the digital signal via two pulse inputs. For electrical isolation, an adapter contained in the scope of supply is available. For the signal conditioning, auxiliary devices can be used. Dynamic Range The artificial heads of the HMS IV generation are characterized by a dynamic range comparable to that of the human ear. This allows sound events to be recorded just as a person would hear them if the person was in the same position as the artificial head during the recording. Battery The mains-independent power supply via a rechargeable battery allows for high mobility and makes the HMS IV.1 ideal for mobile use. The battery level can be polled at any time, for example, via the RC VI remote control. Equalization Five different equalization types can be selected: linear (LIN - no equalization), independent-of-direction equalization (ID), free field equalization (FF), diffuse field equalization (DF) as well as a user-defined equalization setting (USER), which can be tailored to specific needs. External Synchronization Via the AES/EBU input, the artificial head can be synchronized to an external sampling rate. This function is essential for combining several digital artificial head measurement systems or for the connection to other digital systems supported by HEAD acoustics. Automatic System Check The HMS IV.1 automatically performs an extensive system check, during which all components in the signal path are checked for proper function. This makes sure that possible errors or failures in the measurement chain are detected. Deviations from predefined tolerance ranges are corrected automatically. Four-channel Recordings With two HMS IV units, four-channel recordings are possible with sampling rates up to 88 kHz. The compatibility of the HMS IV.1 also allows fourchannel recordings in connection with other front ends. Like all other functions of the HMS IV.1, four-channel recordings in stand-alone operation can be (remotely) controlled via the RC VI and saved to a CompactFlash card. Extensions (optional) HSM V The HSM V seat mount adapter is a stable and convenient platform for mounting an artificial head and other devices on a car seat ® Bluetooth Adapter BTA In combination with the HEAD Remote Control App for Android smartphones or tablets the Bluetooth® adapter allows to control remotely artificial heads from a distance of up to 10 meters (30 ft). The HEAD Remote Control is available via the Download Center on the homepage of HEAD acoustics and can be used in combination with the Bluetooth® adapter of the RC VI, too. HMS IV.1 and HEADlab The modular multi-channel front-end system HEADlab is ideal for the use of one or more HMS IV.1 units. The controllers labCTRL I.1 and labCTRL I.2 have one HMS interface each, and in combination with an input module labHMS, up to four artificial heads can be used. In addition, the input module labDX has one HMS interface, too. Various HEADlab modules are available with which user can customize their systems with up to 360 channels (artificial heads, CAN, OBD-2, FlexRay, pulse, line, ICP sensors, condenser microphones, etc.). HMS IV.1 and SQuadriga II SQuadriga II has an HMS interface for recording artificial head signals via adapters and adapter cables in digital form. Furthermore, with SQuadriga II GPS, CAN respectively OBD-2 and pulse channels and also up to six ICP or other channels can be recorded, both in stand-alone mode as well as in front-end mode.
