The UA-25, USB bus power source drive, with adoption of low noise/wide range power source, treble quality and the compact 24 bits which actualize the balance input/output of professional specification/USB audio of 96kHz correspondence/is MIDI interface.

Extended information

The UA-25 just connects the USB cable adopted the USB bus power source drive which can be used directly, 24 bits/latest and most powerful USB audio of 96kHz correspondence/it is MIDI interface.
With the adoption of USB bus power source drive, actualizing rapid mobility. If it combines with the note personal computer, it is possible to correspond to the treble quality recording at the place AC power source such as outside, there is no it is possible just to construct the ultimate Mobile recording system.

The high accuracy frequency counter, the high resolution frequency generator is adopted to UA-25 itself, the occasion where the audio clock is formed, by the fact that these are controlled to intelligent, the sound which has the transparent impression the operation which is stabilized is actualized.

UA-25 holds down the clip noise of the digital conversion time even with abrupt passing input, being thing to maintain maximum level, loading the analog limiter circuit of the new development which finishes. It can do the recording where the reliability which always is stabilized, even with the input source which such as vocal volume does not fix and acoustic musical instrument is high.
In addition, the compact body also the fact that the abundant input/output terminal is equipped is the big merit of UA-25.

The driver of UA-25, WDM and ASIO (TM) 2.0, corresponds to CoreAudio. It corresponds to the various applications of Windows/Macintosh widely. In addition, ASIO (TM) the direct monitor is possible even with application other than 2.0. It equips on of hardware direct monitoring & off switch in the front panel, furthermore the stereo of the popular monitor time/mono changes with UA-5 and arranges also the switch.

Technical specifications

The number of audio sound recording playback channels:
The sound recording = 1 systematic stereo and the playback = 1 systematic stereo (the time of DIGITAL IN switch OFF = simultaneous sound recording reproducible < 96kHz is excluded, >, only DIGITAL IN switch ON = sound recording possibility) -

signal processing: PC interface = 24 bits (only ADVANCE switch = ON, at 24 bits enabled), AD/DA conversion = 24 bits - sampling frequency: Digital output = 44.1/48/96kHz and digital input = 44.1/48/96kHz, AD/DA conversion = 44.1/48/at the time of 96kHz

ADVANCE switch OFF 44.1kHz fixing - frequency characteristic: 96.0kHz = 20Hz - 40kHz (+ 0dB/- 2dB), 48.0kHz = 20Hz - 22kHz (+ 0dB/- 1dB), 44.1kHz = 20Hz - 20kHz (+ 0dB/- 1dB) - stipulated input level: Input jack L/R (XLR type) = - 60 - - 20dBu, input jack L/R (TRS standard type) = - 36 - + 4dBu - stipulated output level: Output jack L/R (TRS standard type) = + 4dBu (balance), output jack L/R (RCA pin type) = - 2dBu - residual noise level: Output jack = - below 96dBu (signal-noise ratio = 105dB typ. ) (Input 1k &#937; termination and OUTPUT VOLUME = max. INPUT MONITOR = min. IHF-A and typ. )

Interface: USB and digital input/output (in optical type < IEC60958 conformity >, for national welfare in digital audio equipment format correspondence) - connected terminal: < Front panel > Input jack L/R (XLR type < balance, TRS standard type < balance > * input jack R = high impedance correspondence), headphone & jack (stereo standard type) < Rear panel > Digital in connector (optical type), digital out connector (optical type), output jack L/R (TRS standard type < balance >, RCA pin type), MIDI connector (IN and OUT), USB connector (USB Type B)

power source: From USB terminal acquisition
consumed electric current: 480mA - External size: 164 (W) ×133 (D) ×46 (H) mm - mass: 554g (only substance)

accessory: Guarantee, user's registration card, instruction manual, USB cable, RCA pin type -> standard type conversion plug × 2, CD-ROM: "Sound it! < Windows/Macintosh > (Internet corporation)", driver
(0dBu = 0.775Vrms)

Operating condition (Windows edition)
Correspondence OS: Microsoft (R) Windows (R) XP Home/XP Professional/2000 Professional/Me/98 Second Edition

personal computer: Windows which equips the USB port (R) the corresponding personal computer - CPU/the clock: Pentium (R), Celeron (R), or above interchangeable processor/600MHz - memory: Above 128M byte - necessary hard disk capacity: Above 200M byte

Connecting to the USB terminal which corresponds to USB2.0, you can use. However, performance of the product USB1.0/is not different from the case where you connect to 1.1 terminals even with in that case.
In the Transmeta Crusoe processor on-board type it is verified that the sound being cut off occurs.

In the personal computer which loads the chip set of the VIA corporation we recommend above 1GHz. When it is under 1GHz, at the time of sound recording playback the condition where sound breaks off depending upon the environment of errand is verified.

In regard to the compatibility of the interchangeable processor itself it is unable to guarantee.

Operating condition (Macintosh edition)
Correspondence OS: MacOS 9, 10.2 or more * all Japanese editions - corresponding personal computer: Macintosh which equips the USB port usually (R) the series - CPU/the clock: PowerPC above G3/400MHz - memory: When above the 128M byte (it is Mac OS X, above the 256M byte)

The classic of Mac OS X (Classic) with environment we do not operate. Please use when classic environment has not been started.

With Mac OS 9 you use, after after the OMS 2.3.3 of the OPCODE corporation, or the FreeMIDI 1.35 of the Mark of the Unicorn corporation is necessary. You cannot use with the software which does not correspond to OMS and FreeMIDI.
