2. Input sensitivity knobs

These adjust the input level of the signals input to the front panel combo input jacks (1).

3. Input impedance select switch

Use this switch to select either high impedance (Hi-Z) or low impedance (Lo-Z) as appropriate for the type of device connected to the INPUT 2/R phone type input jack of the combo input jacks (1). Turn this switch on (inward position) to select high impedance (Hi-Z) if a guitar or bass is connected. Turn this switch off (outward position) to select low impedance (Lo-Z) if a microphone is connected.

Combo input jack INPUT 1/L is fixed at low impedance (Lo-Z).

4. Peak/Limiter indicator

This indicates whether the input signal is distorting or the limiter is operating.

Limiter switch	Status
Limiter on	The indicator will function as a limiter indicator. When the input signal exceeds a certain level, the limiter will operate and the indicator will light green.
Limiter off	The indicator will function as a peak indicator. Use the input sensitivity knobs for each input jack to adjust the input level so that the peak indicator does not light red.

5. USB indicator

This will light blue when the UA-25 is connected to your computer via a USB cable and the computer has correctly detected the UA-25.

6. Digital input switch

If you want to record the digital input, turn this on (inward position).

This allows you to synchronize with an external digital device connected to the digital input connector (16).

Digital input switch	Mode Status
	Digital input mode	The input from thedigital inputconnector (16)is sent to the computer.

On and no digital device is connected to the digital input connector	LoopBack mode	The audio signal that is output from your computer via USB will pass through the UA-25 and return to the computer.

* When the digital input switch is on, you will not hear the sound from the computer.
* When the digital input switch is on, the settings of the Direct Monitor section are ignored. In other words, operating the direct monitor switch (8), STEREO/MONO select switch (9), or direct monitor volume (10) will have no effect.

7. Digital input indicator

This indicator will blink when you turn on the digital input switch. When an external digital signal device is connected to the digital input connector, the indicator will change to steadily lit.

8. STEREO/MONO select switch (Direct Monitor section)

This selects whether the signal input via the combo input jacks (1) is to be monitored in stereo (STEREO) or in monaural (MONO).

If you have connected a guitar to only INPUT 2/R, use the monaural setting (inward position). Even if the monaural setting is selected, the audio signal sent via USB to your computer is stereo.

* If the digital input switch (6) is on, operating the STEREO/MONO select switch has no effect.

9. Direct monitor switch (Direct Monitor section)

This selects whether the signal input via the combo input jacks (1) is to be output from the headphone jack (13) and master output jacks (14).

The direct monitor on/off setting can be controlled directly from ASIO 2.0 compliant software such as Cubase.

On(Direct Monitor indicator lit)	The input signal will be output.
Off(Direct Monitor indicator unlit)	The input signal will not be output. Use this setting if the audio signal is being passed through within your computer, or if you are monitoring the input signal directly via an external mixer.

* This setting does not affect the signal input via the digital input connector (16).

10. Direct monitor volume (Direct Monitor section)

This adjusts the volume at which the signal input via the combo input jacks (1) is output from the headphone jack (13) and the master output jacks (14). When this is turned fully clockwise, the signal being monitored will be at +6 dB.

11. Direct monitor indicator (Direct Monitor section)

This indicator will be lit if direct monitor is on, and unlit if direct monitor is off. If the digital input switch (6) is on, the Direct Monitor indicator will be extinguished and the direct monitor function will be off.

12. Output volume

This adjusts the volume of the output from the headphone jack (13) and the master output jacks (14).

13. Headphone jack

Headphones are connected to this jack. This outputs the same sound as the master output jacks (14). Sound will still be output from the master output jacks even if headphones are connected.

Rear Panel

14. Master output jacks (phone type, RCA phono type)

These are analog audio output jacks. The phone jacks and RCA phono jacks output the same sound. You may use whichever type of jack is appropriate for the connected device or the type of cable.

15. Digital output connector (optical)

Use this connector when you want to digitally output an audio signal to a digital audio device such as MD or DAT. Use an optical cable to make connections.

16. Digital input connector (optical)

Use this connector when you want to digitally input an audio signal from a digital audio device such as CD, MD, or DAT. Use an optical cable to make connections.

17. MIDI IN/OUT connectors

You can connect these to the MIDI connectors of your MIDI device to transmit and receive MIDI messages.

* The MIDI IN/OUT connectors are not available if you are using Standard driver mode (p. 13).

18. Limiter switch

This turns the UA-25's hardware limiter on/off.

If a sudden, high-volume sound is input to the combo input jacks (1), the limiter applies mild compression to prevent clipping from occurring at the AD converter.

* Clipping noise will be heard if the input signal exceeds the capacity of the limiter.

19. Phantom power switch

This is an on/off switch for the phantom power supplied to the XLR connectors of the combo input jacks (1) on the front panel.

* You must leave the phantom power turned off (right position) unless condenser mics requiring phantom power are connected to the XLR jacks. Supplying phantom power to a dynamic mic or an audio playback device may cause malfunction. For details on the requirements of your mic, refer to its owner's manual.
(The UA-25's phantom power supply: DC 48 V, 8 mA maximum)

20. USB connector

Use a USB cable to connect the UA-25 to your computer.

21. ADVANCE (mode select) switch

This switches the driver operation mode.

If you change the setting of this switch, you must close all software, disconnect the USB cable that connects the UA-25 to your computer, and then re-connect the USB cable.

On (Advanced mode)

You can use the included UA-25 driver to record, play, and edit audio from your sequencer software or audio editing software with high quality and stable timing.

Off (Standard driver mode)

Choose this mode if you are using software that uses the standard audio driver included with your operating system.

* The sample rate will be fixed at 44.1 kHz/16 bit regardless of the setting of the UA-25's sample rate select switch.
* The MIDI IN/OUT connectors are not available when using Standard driver mode.

For details on these operating modes, refer to "About the driver modes"

(Windows, p. 14; Macintosh, p. 32).

22. 96 kHz REC/PLAY select switch

When using the UA-25 at 96 kHz, this switches between 96 kHz REC (recording) or 96 kHz PLAY (playback). If you change the setting of this switch, you must disconnect the USB cable that connects the UA-25 to your computer, and then reconnect the USB cable.

23. Sample rate select switch

This specifies the sample rate at which audio data is recorded and played back. If you change the setting of the Sample Rate select switch, you must close all software, disconnect the USB cable that connects the UA-25 to your computer, and then reconnect the USB cable.

* 96 kHz can be used only in Advanced mode. Also, you will need to set the 96 kHz REC/PLAY select switch to either REC (recording) or PLAY (playback) in order to record or play back successfully.
* If you are using Standard driver mode (the ADVANCE switch turned off), the sample rate is fixed at 44.1 kHz regardless of the Sample Rate select switch setting.

About the driver modes

A “driver” is software that transfers data between the UA-25 and application software running on your computer, when your computer and the UA-25 are connected by a USB cable. The driver sends data from your application to the UA-25, and from the UA-25 to your application.

The UA-25 has two operating modes, Advanced mode and Standard driver mode, and a different driver is used by each mode.

Advanced mode

This is the operating mode when the rear panel ADVANCE (mode select) switch is ON. You can use the native driver included on the UA-25 Driver CD-ROM to record, play, and edit audio with high quality and stable timing. In Advanced mode, audio signals are transferred between the UA-25 and the computer at a bit depth of 24 bits and a sample rate of 44.1/48/96 kHz. Choose Advanced mode if you are using software that supports 24-bit audio, such as the Cakewalk series or Cool Edit; or ASIO-compatible software that can record, play, and edit high-quality audio, such as Cubase VST or Logic Audio. Normally, you should use Advanced mode.

* You must use Advanced mode if you want to use MIDI.

Standard driver mode

This is the operating mode when the rear panel ADVANCE (mode select) switch is OFF. The standard USB audio driver provided by Windows will be used. In Standard driver mode, audio signals are transferred between the UA-25 and the computer at a bit depth of 16 bits and a sampling rate of 44.1 kHz. Choose this mode if you are using software that uses the standard functionality provided by Windows, such as software that uses the CD-ROM drive of your computer to play CD audio, or that uses the software synthesizer included with Windows.

* The driver included with Windows does not support ASIO.
* The MIDI IN/OUT connectors are not available when using Standard driver mode.

If the sample data plays correctly, the UA-25 is correctly connected to your computer, and the driver has also been installed correctly.

Use of the song data supplied with this product for any purpose other than private, personal enjoyment without the permission of the copyright holder is prohibited by law. Additionally, this data must not be copied, nor used in a secondary copyrighted work without the permission of the copyright holder.

About the driver modes

A “driver” is software that transfers data between the UA-25 and application software running on your computer, when your computer and the UA-25 are connected by a USB cable. The driver sends data from your application to the UA-25, and from the UA-25 to your application.

The UA-25 has two operating modes, Advanced mode and Standard driver mode, and a different driver is used by each mode.

Advanced mode

This is the operating mode when the rear panel ADVANCE (mode select) switch is ON. You can use the native driver included on the UA-25 Driver CD-ROM to record, play, and edit audio with high quality and stable timing. In Advanced mode, audio signals are transferred between the UA-25 and the computer at a bit depth of 24 bits and a sample rate of 44.1/48/96 kHz. Choose Advanced mode if you are using software that supports 24-bit audio such as the Cubase VST or Logic Audio; or ASIO-compatible software that can record, play, and edit high-quality audio, such as Cubase VST or Logic Audio.

Normally, you should use Advanced mode.

* You must use Advanced mode if you want to use MIDI.

Standard driver mode

This is the operating mode when the rear panel ADVANCE (mode select) switch is OFF. The standard USB audio driver provided by Mac OS will be used. In Standard driver mode, audio signals are transferred between the UA-25 and the computer at a bit depth of 16 bits and a sampling rate of 44.1 kHz. Choose this mode if you are using software that uses the standard functionality provided by Mac OS, such as software that uses the CD-ROM drive of your computer to play CD audio, or that uses the software synthesizer included with Mac OS.

* The driver included with Mac OS does not support ASIO.
* The MIDI IN/OUT connectors are not available when using Standard driver mode.

The installation procedure will differ depending on your system.

Please proceed to one of the following sections, depending on the system you use.

• Mac OS X users....(p. 33)
  • Mac OS 9 users .....(p. 36)
