TECHNOLOGY NEWS Sony Brings the PCM-D100 to Europe

FIRST LAUNCHED back at AES in New York, Sony has announced that its newest PCM recorder will be making its way to Europe early this year. The flagship of Sony’s portable digital recorder

range, the PCM-D100 is compatible with 2.8MHz/1-bit direct stream digital DSD, a format that records source sounds using digital signals, but in a format that closely resembles analogue waveforms. It is also compatible with recording and playback in 192kHz/24-bit linear PCM High Resolution Audio. “This new model is Sony’s highest-quality

portable digital recorder, designed to faithfully reproduce sound sources such as instrument performances and sounds of nature, as closely to the original as possible,” said James Leach, marketing manager, professional audio, Sony Europe. “The PCM-D100 recorder is part of our High- Resolution Audio initiative, a complete series of

products designed to help music lovers conveniently access and enjoy the digital music they love in the best playback quality available.” The recorder features a highly sensitive

directional microphone that incorporates a newly- developed 15mm unidirectional mic unit. This enables the user to adjust the sound collection range of the mic to suit various sound, from performances with a small number of people, through to concert halls with a much larger group of performers. In comparison to conventional 24-bit D-A

converters, the PCM-D100 has adopted a higher- class 32-bit converter to achieve accurate playback of the sound. The headphone amp incorporates a high-capacity, ultra-low impedance 0.33F (330000µF) electric double-layer capacitor (EDLC), equivalent to 750 times the capacitance of conventional capacitors.

PreSonus Adds Miniature Version to Eris Line-up

contour, a four-position Acoustic Space switch controls a second-order shelving filter, centred at 1kHz, that provides three attenuation points (no attenuation, -2dB, and

ROUNDING OUT its latest studio monitor offering, PreSonus has revealed the smallest version of its Eris line – The Eris E4.5. Designed for home studios and

situations where space is at a premium, the E4.5 features a 4.5in Kevlar low-frequency transducer, a 1in silk-dome, high-frequency tweeter with protective grille, and a rear bass-reflect port. Each speaker is powered by a 25W Class AB amplifier with peak SPL rated at

-4dB), giving users control of the bass response. A high pass switch sets the low-frequency cut-off (second- order slope, -12dB/octave) to be flat, 80Hz, or 100Hz. You also get continuously adjustable (±6dB) high frequency and midrange controls. For connections, the E4.5 features a balanced 0.25in TRS and unbalanced 0.125in TS, RCA inputs, as well as a 0.125 stereo headphone output.

WaveDynamics Amps to Make a Splash

THE NEW Audac SMA and SMQ Series of two- and four-channel power amplifiers include the new WaveDynamics digital signal processor in combination with a 2.5in LCD display that is claimed to give “an unmatched user experience with intuitive functions overview for easy configuration”. Acoustics can be optimised using

the filters selectable between Low/High & Band Pass and the seven-band equaliser, which both have adjustable frequencies and Q-factor. Other provided functions are delay (for time-alignment of different speakers) and dynamic bass boost. These settings can be custom- configured using the amplifier’s front panel, whereby access can be given in two different levels (User and Administrator) using password or

New Developments from RTW

THIS YEAR will see a raft of new developments from German manufacturer RTW for its TouchMonitor range of audio metering and monitoring products. Following the recent release of the DPP’s

recommendations that UK audio should be compliant to the EBU R128 Audio Loudness specification by October 2014, demonstrating compliance will be essential and the first of RTW’s developments, the Loudness Quality Logger (LQL), addresses this problem. LQL is a software module for loudness

logging, true peak data analysis, and reporting for the TM9, TM7, and TMR7 meters. Data from an LQL-enabled TouchMonitor will be delivered via an IP connection to a PC installed with RTW’s free downloadable software where the loudness information will be logged and stored. R128-compliant loudness metering tools available

for the TouchMonitor series include loudness and SPL display, loudness range (LRA), true peak, moving coil, and a loudness radar display. RTW is releasing a Timecode Reader module to

decode and display SDI- embedded or LTC timecode. In addition, the Timecode

Reader is available for the LQL logging application. The third innovation is a 16-channel AES3 I/O

interface for the TouchMonitor TM7 for all digital environments.

USB-key protection. Loudspeaker protection is provided by an output power limiter where maximum output power (in Watts) for every channel can be configured. Full system configurations can be selected from a library, which includes loudspeaker performance parameters, and uploaded with a USB drive. The lightweight Class D amplifiers

are available in 350W, 500W, and 750W versions and incorporate flexible input and output configuration, XLR and terminal block source compatibility, and RS-232 control.
