NTI ROOM ACOUSTICS OPTION Firmware for XL2 Analyser

NTI AUDIO XL2 ACOUSTIC AND AUDIO ANALYSER

NTi XL2 is a powerful, portable audio analyser, which, when coupled with a suitable microphone, becomes a sound level meter to Class 1 or Class 2 standard and a comprehensive acoustic analyser as well. Supplied with software which connects the instrument to a PC to transfer data or log data it is an all-in-one tool intended for applications such as live sound, sound installations, recording studios, broadcast environmental noise measurements service and repair centres. The analyser is available as a stand-alone test instrument, with a choice of NTI Audio microphones or in kits together with a microphone, signal generator and other accessories. Firmware packages are offered to add reliable measurement of STI, speech transmission index and extended features for sound level and acoustic measurements.

XL2 Analyser

The hand-held instrument has an LCD showing menu options and measured values. It can be used with the rechargeable Lithium-polymer battery supplied for up to four hours. Dry cell batteries will give a similar life, or a external power supply can be used, which will charge the Lithium polymer whilst in operation. An XLR connector on the top offers a high-impedance, balanced connection for the audio input, with 48V phantom powering available for a microphone. Detection of NTI Audio M4261 or M2211 microphones is automatic. An RCA (phono) socket takes unbalanced signals. A 3.5mm headphone socket provides for monitoring the incoming signal. A microphone is built-in, which may be used for polarity and delay measurements as well as voice note recording to a Mini SD card, not supplied, up to 2GB, which can also be used to record screen shots, log measurements and to record WAV files, AD-PCM compressed as standard, but to 24-bit 48kHz quality with the Extended Acoustic Pack option. There is an internal speaker; a USB interface may be used for recharging the internal Li-Po battery as well as transfer of data.

The XL2 has a flexible user interface; the measurement screens may be personalised and ‘only a limited subset of the comprehensive functionalities enabled for simplified operator interfaces. Advanced users may access all menus, settings and store their preferred measurement configurations’. For basic users the XL2 offers ‘audio and acoustic analyser fixed operator interfaces with specific pre-defined settings. The XL2 boots up with exactly the required measurement parameters according the pre-defined instrument configurations. This ensures accurate measurements achieved by advanced and basic users.’

Real Time Analyzer RTA

The RTA perfectly suits tasks such as optimization of sound systems and rooms. The XL2 measures and logs wideband values and the real time spectrum in 1/1 or 1/3 octave-band resolution according to IEC 61260 class 0. The sound level meter results of the wideband and RTA spectrum are simultaneously available. Frequency weighting: A, C, Z (=flat). Time weighting: Fast, slow and optional impulse.

Acoustic Analyzer

FFT Analysis

The real-time FFT is the ideal tool for visualization of comb filters and narrow band effects. It measures the actual level and the averaged level Leq in three ranges over the entire audio band. The optional Extended Acoustic Pack offers an additional high-resolution Zoom-FFT up to 0.4 Hz steps in the frequency range 5 Hz - 20 kHz and adds the linear audio recording (24 Bit, 48 kHz). The Spectral Limits Option extends the FFT Analysis with trace capturing, relative curve display and comprehensive tolerance handling.

Reverberation Time RT60

The XL2 measures the energy decay in the range from 63 Hz to 8 kHz by the Schroeder method in 1/1 octave bands. Automatic triggering and averaging of multiple measurements simplifies the operation and minimizes the measurement time. Use either an impulse source or an interrupted pink noise as the test signal. The optional Extended Acoustic Pack extends the reverberation time measurement to a 1/3 octave resolution.

Polarity

For a stereo sound image, it is important to match the polarities of the left and right speakers. The XL2 measures the polarity of cables, single speakers and speaker cabinets. The detailed result page displays the measured polarity as octave bands from 125 Hz to 8 kHz. This allows in-depth verification of the polarity - frequency relation. The polarity test signal is provided by the NTi Audio Test CD or the Minirator test signal generator.

Delay Time

The delay function supports the accurate setup of delay lines and thus the optimization of the directionality of the signal source. The XL2 measures the delay time between the electrical reference signal and the acoustic signal from the speaker. The required delay settings are displayed automatically, allowing the audio engineer to set the measured delay time directly into the delay device in the rack.

Analog Audio Analyzer

Level RMS / THD+N

The XL2 with balanced XLR and unbalanced RCA inputs offers a comprehensive, high performance audio analyzer. It simultaneously measures balance, level, distortion (THD+N) and frequency. The internal loudspeaker or headphone output offers audible monitoring of either the input signal or just the residual distortion. The optimized low distortion and low noise design enable level measurements down to -112 dBu and residual distortions typically lower than -100 dB, which is unmatched in handheld instruments.

Audio Spectrum

Spectral audio measurements are offered in the units Volt, dBu and dBV within the following measurement functions: Sound Level Meter (1/3 and 1/1 Octave), FFT, 1/12 Octave (optional)

Scope

The scope function visualizes the waveform of the electrical input signal. It triggers to the fundamental frequency and selects the scaling of the X-axis (time) and Y-axis (level) automatically. The fundamental or most dominant frequency is displayed above the scope screen.

Included accessories: Test signal CD, USB cable, Li-Po battery, hand-strap, operating manual.

ACCESSORIES

Power Supply

This powers the analyser and charges the internal Li-Po battery in the XL2 in circumstances where USB charging is inappropriate.


Battery Charger - With battery

This charges the Li-Po battery externally from the XL2. It is supplied with a spare Li-Po battery.


Mounting Adapter

This mechanical adapter piece mounts the XL2 on a microphone stand. Adapters for 3/8 inch or 5/8 inch threaded stands are included. NTI Audio code: 600 000 372.


ASD Cable

This is an five metre cable with male and female 3-pole XLR connectors, used when it is desirable to mount the measuring microphone away from the XL2. Up to four ASD cables may be connected in series. The ASD cable is wired with four connections: the XL2 uses the metal body of the XLR input as an extra conductor. As a result the M4261 and M2211 microphones can be identified automatically. If the microphones are connected with a standard microphone cable, parameters must be entered manually.


System Case

Made from re-enforced plastic and filled with foam, 600 000 701 has dedicated cutouts for an XL2 analyser, a Minirator MR-Pro, and a measurement microphone with spaces for batteries cables and adapters.


SPL Stack Light

This is a tubular lamp fitting, intended for such applications as indicating noise levels at live events or clubs or in noisy industrial environments. The light has three lamp sections, coloured green, amber and red, and connects to the XL2 via the Digital I/O Adapter Box. Connection is via a 5-pin XLR on a two metre captive cable. Fixing holes are provided in the base for permanent applications. Dimensions: 232 x 95 x 95mm. NTI Audio code: 600 000 382.


Digital I/O Adapter Box

This is connected to the digital I/O interface of the XL2 to provide a 'Turnkey solution' controlling an external SPL Stack Light. Limit settings may be customised in the XL2. There is a female 5-pole XLR connector for connection to the Stack Light, a male 3-pole mini-XLR connector to link to the XL2 with the supplied cable (2 metres) and an inlet for the supplied 24V power adapter. Dimensions: 170 x 85 x 35mm. NTI Audio code: 600 000 381.
