1 Data Sheet labcore (Code 7700) ACQUAlab modular multi-channel front end for speech and audio quality testing Overview labcore front view (with optional modules) DESCRIPTION labcore is the new front end of the ACQUAlab generation which was started a few years ago with the now well-established front ends MFE VIII.1 and labbgn. With labcore and its new modular concept, the ACQUAlab front end generation is now brought ahead to the next level. Offering multiple channels instead of being limited to two channels, a wide variety of analog and digital inputs and outputs, an improved processing performance and high-performance interfaces, labcore is an all-inone solution for measuring the audio and speech quality of a wide range of devices. labcore is used as primary front end in conjunction with the communication quali ty analysis system ACQUA and can be easily combined with other HEAD acoustics front ends and components. Connected to a notebook or PC via USB (Plug & Play), it is configured and controlled by ACQUA. Via labcore and its optional hardware and software extensions, ACQUA performs auto ma ted measurements according to international, HEAD acoustics or user-defined standards. labcore thus serves for system optimization and development as well as quality control and bench mark testing in all areas where excellent voice and audio quality of telecommunication and audio devices as well as transmission systems plays a decisive role. The front end settings can be easily controlled via the intuitive ACQUA settings manager. They can be stored and assigned to selectable measurement sequences. For mobile use, the HEADlab power box is optionally available as power supply D7700e labcore is equipped with a further developed mainboard based on the established technology of the ACQUAlab front end generation and thus e.g. provides more processing power. The housing of labcore has a height of two rack units, other dimensions are comparable to existing ACQUAlab front ends. Numerous important interfaces are already available in the basic unit, such as: Two analog Input and two analog Output connectors. Headphone output (6.3 mm headphone jack), for measuring as well as monitoring purposes. USB Host Type C connector, for measurements of e.g. USB headsets. By using an adapter (standard delivery item), USB Host Type A is also available. AES In/Out, integrated into a Sub-D 15pin connector. Pulse in- and outputs with TTL levels are available as well. An additional AES digital audio input and output (XLR 3-pin), for audio data exchange, e.g. with other front ends. Two sockets, for general purpose input and output (GPIO) e.g. Pulse, Clocks etc. HEADlink connector, for connecting HEADlink devices such as MSA I is also available. USB port (Type B), for connecting the ACQUA PC for status information, data acquisition and control purposes. ADAT/SPDIF optical, TOSLINK connector I²S Inter-IC Sound on Digital Audio labcore is the new modular multi-channel front end of the ACQUAlab generation by HEAD acoustics. Its wide choice of high-performance analog and digital interfaces as well as its versatility and future-proof technology make labcore the state-of-the-art all-in-one solution for testing speech and audio quality precisely and efficiently. Measuring digital and analog telecommunication and audio devices as well as transmission systems, analyzing headsets or headphones, binaural equalization, setups with two artificial head measurement systems, VoIP reference gateway: labcore is versatile and provides everything in one device depending on the selected configuration and optional extension modules. MODULES & OPTIONS labcore can easily be extended by up to ten hardware modules and by various software options depending on applications and measuring purposes: corebus (Code 7710), I/O Bus Mainboard: corebus is required as bridge between the mainboard and the hardware extension modules. The high-performance bus mainboard is equipped with a Field Programmable Gate Array (FPGA), which ensures a high data transfer rate. coreout-amp (Code 770), Power Amplifier Module: labcore provides two power amplifiers via the optional module coreout-amp. Each amplifier provides 0 Watt RMS (class D technology). Output for both amplifiers is one Speakon 4-pin socket. Thus, test setups with two artificial head measurement systems such as for In-Car Communication testing or acoustic-to-acoustic (end-to-end) testing can be realized easily. The module is also capable of operating e.g. small loudspeakers. labcore can be equipped with up to two coreout-amp modules. corein-mic4 (Code 7730), Microphone Input Module: The module corein-mic4 provides four LEMO 7-pin microphone inputs for externally polarized microphones with TEDS support. With this module, labcore allows concurrent connection of both ears of an artificial head measurement system as well as measurement microphones. Users choose which

2 inputs should be used via the ACQUA software. Thus, labcore enables fully automated measurements, as a manual swap of microphones is no longer necessary. corebeq (Code 7740), Binaural Equalization: The software option corebeq extends labcore to a binaural equalizer. Thus, labcore allows the digital equalization of artificial head signals, all in real time. For this purpose, individual equalization filters for use with the corresponding artificial head are determined by HEAD acoustics and stored in the front end. These filters are then available in ACQUA for the following digital equalization types: Linear, Independent-of-Direction (ID), Freefield (FF), Diffuse-field (DF), User-specific. coreout-a (Code 7750), Analog Output Module: The module coreout-a provides two analog two-channel /XLR outputs. The connectors are switchable and can be used in balanced and unbalanced mode. The outputs are high-precision and low noise, thus perfectly suitable for demanding electro-acoustic measurements. corein-a (Code 7760), Analog Input Module: The module corein-a provides two analog two-channel /XLR inputs. The connectors are switchable and can be used in balanced and unbalanced mode. The inputs are high-precision and low noise, thus perfectly suitable for demanding electro-acoustic measurements. coreip (Code 7770), labcore I/O Module, Voice over IP Reference Gateway: This module replaces the measurement front end MFE VIII.1 (Code 6484). Using the coreip module, labcore serves as reference gateway for voice quality measurements of digital communication devices and transmission systems. The module supports the main features according to RFC 361 and offers an integrated SIP-VoIP client with numerous voice codecs. labcore supports the same protocols and codecs as MFE VIII.1. coreip-imp (Code 7771), labcore VoIP Impairment Option: This software option replaces MFE VIII.1-IMP (Code 6496). coreip-imp provides optional network impairment for labcore. It allows reproducible measurements under impaired network conditions (jitter, delay, packet loss) even with activated DTX (Discontinuous Transmission). The impairment option requires the module coreip (Code 7770). coreip-amr (Code 777), labcore VoIP AMR Codec Option: This hardware codec option replaces Cod-AMR (Code 6485). coreip-amr provides the additional codecs AMR-NB, G.7. AMR -WB, GSM Enhanced Full Rate and G.79 Annex A and Annex B for use with labcore. coreip-amr requires the module coreip (Code 7770). coreip-evs (Code 7773), labcore VoIP EVS Codec Option: This codec option replaces Cod-EVS (Code 6495). coreip-evs is the EVS (Enhanced Voice Services) software codec option for labcore. It supports all specified bandwidths from narrowband to fullband and with all bit rates and modes (incl. AMR-WB interoperable mode). coreip-evs features static jitter buffer for accurate delay conditions instead of EVS s adaptive jitter buffer. The EVS codec option requires the module coreip (Code 7770). A hardware extension (cf. MFE VIII.1-SPE) is no longer required. coreip-opus (Code 7774), labcore VoIP OPUS Codec Option: This codec option replaces Cod-OPUS (Code 6494). coreip-opus provides the optional labcore front panel (with optional modules) labcore back panel (with optional modules) 1.17 D7700e software codec Opus (Audio, -Channel) for use with labcore. It requires the module coreip (Code 7770). corebt (Code 7780), labcore I/O Module, Bluetooth Reference Access Point: This module replaces the measurement front end MFE XI (Code 648). corebt means the complete integration of MFE XI into labcore. With corebt, labcore serves as universal access point for acoustic and electrical measurements of voice and audio devices (mobile phones, headsets, headphones, hands-free devices (head unit), Bluetooth loudspeakers) with Bluetooth wireless technology. The module supports the same profiles as MFE XI. corebt-ext (Code 7781), labcore Bluetooth Extended Codec Option: This module replaces MFE XI-EXT (Code 649). corebt-ext is an optional extension pack for the corebt module. The extension includes the wideband capability for handsfree profiles (msbc codec) and the aptx codec for ADP profiles. The Bluetooth extended codec option corebt-ext requires the module corebt (Code 7780).
