Front Panel
A INPUT 1/2 jacks
These inputs are intended for microphones with XLR connectors or instruments with 1/4"
jacks. When connecting devices to the INPUT jacks on both the front and rear panels, the
input on the front panel takes precedence and will automatically be active.
B [GAIN 1]/[GAIN 2] knobs
Controls the preamplification of the signal being applied to INPUT 1/2 on the front/rear
panel.
While recording, make sure to record at the highest level possible (without distortion or clipping) to
get the greatest benefit from the wide dynamic range of the 24-bit converter. Always remember
that a properly recorded, clean take is far more valuable than having to use the best corrective
plug-in to fix an inferior take.
C SIGNAL and CLIP LED
Provides visual level monitoring of the signal to be recorded on INPUT 1/2 on the front/rear
panel. The lower blue LED indicates the presence of a signal, while the upper red one indicates
an overload of the input converter.
D [+48V] switch
Supplies +48 V phantom power to INPUT 1/2 on the front panel. Turn this switch on if you are
connecting a condenser microphone that requires external +48 V power.
Connectors and controls
Observe the following precautions when turning on phantom power.
■ Make sure that the PHANTOM switch is off when phantom power is not needed.
■ Make sure that no equipment other than phantom-powered microphones is
connected to the inputs 1 and 2 jacks on the front panel when turning phantom
power on. Applying phantom power to equipment other than phantom-
powered microphones can damage the equipment. The exception to this rule is
balanced dynamic microphones, which can safely be left connected while
phantom power is applied to input jacks 1 and 2.
■ To minimize the possibility of speaker damage, turn phantom power on ONLY
while your power amplifier or powered speakers are switched off. It’s also a good
idea to turn the mixers output controls — [MASTER] knob and HEADPHONE
LEVEL knob — all the way down when turning phantom power on.

Connectors and controls
E [MASTER] knob
Controls the levels of the analog outputs (OUTPUT 1/2 or OUTPUT 3/4). The output pair to be
controlled can be selected via the Push function (OUTPUT 1/2 or OUTPUT 3/4 or both jacks).
The output pair currently being controlled can be monitored by the MAIN/MONITOR LED. In
addition, pressing and holding the knob for 2 seconds or more will mute the channels cur-
rently being controlled. This can be used to switch back and forth between two monitor
speaker sets for a direct comparison. This function is also available via the GO46 Control
Panel. (See page 20.)
F MAIN and MONITOR LED
Indicates the output pair currently being controlled by the master or muted. The MAIN LED
corresponds to OUTPUT 1/2 jacks, MONITOR LED to OUTPUT 3/4. The following overview
describes the operation and displays:
G HEADPHONE LEVEL knob
Adjusts the output level of the PHONES jack.
H PHONES jack
Output for a 1/4" stereo headphone jack. The signal from OUTPUT 3/4 on the rear panel is
always available at the PHONES jack. The actual signal available there depends on the routing,
which you can set up to suit your needs in the GO46 Control Panel. (See page 20.)

Connectors and controls
Rear Panel
I INPUT 1/2 jacks
The GO46 System features two high-quality analog mono inputs. The connections have been
designed for balanced/unbalanced phone 1/4" jacks. The gain for these inputs can also be set
using the GAIN knobs on the front panel. When connecting devices to the INPUT jacks on
both the front and rear panels, the input on the front panel takes precedence and will auto-
matically be active.
J INSERT 1/2 jacks
These are 1/4" stereo headphone jacks for channel insert ins and outs. External effects such as
compressors and effect processors can be inserted into the recording path before the signal is
sent to the A/D converter.
K OUTPUT 1/2 jacks
The connections have been designed for balanced/unbalanced phone 1/4" jacks for main out-
put. You can connect mixers, powered speakers, or amplifiers. The analog outputs operate
with instrument-compatible levels of 2.0 Vrms.
L OUTPUT 3/4 jacks
The connections have been designed for balanced/unbalanced phone 1/4" jacks for monitor
output.
M DIGITAL IN jack
This digital audio jack is for the digital input of audio signals. The interface can receive sample
rates of up to 24-bit/96 kHz. The input signal can be adjusted in the Digital Mixer of the GO46
Control Panel. (See page 20.)
When recording from a digital source, make sure that the sampling rates of both devices (e.g.
DAT recorder and laptop) are synchronized. The S/PDIF protocol contains a signal called
wordclock for this purpose. If the Master Clock switch is set to “EXTERNAL” in the GO46 Con-
trol panel, the GO46 will automatically synchronize to it and the “DIGITAL IN” channel will be
available in the mixer.
ASIO applications such as Cubase often have an option to switch the hardware from an inter-
nal to an external (sometimes also called S/PDIF) clock source. This changeover currently has
no effect on the GO46.

N DIGITAL OUT jack
This digital audio jack is for the digital output of audio signals. The interface can transmit sam-
ple rates of up to 24-bit/96 kHz.
For playback, set the routing in the Control Panel to the digital output. AC3 and DTS can also
be played back via the digital output. Select “NON AUDIO” for the digital output in the Con-
trol Panel under “ROUTING”. (See page 22.) The non-audio signals are not sent to the analog
outputs.
O IEEE1394 (FireWire) port
Connects the GO46 system to your computer using the included IEEE1394 (FireWire) cable.
P MIDI IN jack
Connects MIDI devices such as MIDI keyboards and DAW controllers. For connecting MIDI
devices, connect the MIDI OUT terminal of the MIDI device to this jack using a MIDI cable.
Q MIDI OUT jack
Connects to MIDI devices such as synthesizers and tone generators. For connecting MIDI
devices, connect the MIDI IN terminal of the MIDI device to this jack using a MIDI cable. Con-
ventional DAW applications usually allow you to route incoming MIDI data through the OUT
jack, using the Thru (or MIDI Echo) function.
R DC IN jack
Connects the AC power adaptor to this jack.

Windows drivers
The GO46 audio interface features two kinds of audio drivers that support a variety of
applications. The audio drivers support all bit rates between 8 and 24 bits with all common
sample rates between 32 and 192 kHz. (Supports digital I/O up to 96 kHz)
MME driver
The Windows MME driver is a multi-channel driver that supports all six outputs (4 analog and 2
digital). The specific routing options for these drivers can be found in the GO46 Control Panel. In
most Windows programs, you will encounter MME drivers with the designation “GO46(GO46
(1)) In 1” for input channel and “GO46(GO46 (1)) MC Out” for output channel.
ASIO driver
ASIO (Audio Streaming Input Output) is an audio transfer protocol developed by Steinberg. The
advantage of the ASIO driver is the extremely low audio recording and playback delay times, also
known as latency. Values of around 5 ms on fast, cleanly configured systems — at sample rates
exceeding 96 kHz — are quite realistic. The format also supports sound cards with multiple
inputs and outputs — so-called multi-I/O cards, as well as direct monitoring and multi-client
mode (ASIO 2.0 or later). In the programs that make use of Steinberg’s ASIO interface, the ASIO
driver for the GO46 is listed as “ASIO GO4x.”

For Cubase, the inputs are called “Line 1/2 left GO46”, “SPDIF left GO46”, etc. Also, the outputs
(generally called “busses” or “channels”) available in the individual programs are generally called
“Multichannel 1 GO46”, “SPDIF/AC3 left GO46”, etc.

MIDI driver
This driver is for using the GO46 MIDI IN and MIDI OUT ports. The driver is designated as
“GO46(GO46 (1)) Midi In 1” (MIDI input) and “GO46(GO46 (1)) Midi Out 1” (MIDI output).
MIDI files, which can be played back using Windows’ media players, are also to be transferred to
externally connected devices such as synthesizers and tone generators. Open the “Sounds and
Audio Devices Properties” window from the Windows Control Panel, go to “Audio” and set the
“MIDI music playback” device to the driver mentioned above.

Drivers
Mac OS X drivers
In Mac OS X, the GO46 system is supported completely by Apple CoreAudio and CoreMIDI.
Device-specific drivers are not required. If you would like to use the GO46 for the default system
sound output, select the GO46 audio driver in [System Preferences] → [Sound] → [Output].
The CoreAudio/MIDI driver can also be selected in DAW applications such as Cubase. Buffer sizes
generally can also be configured there to accelerate access to the audio system.

The GO46 Control Panel is quite intuitive and should not present beginners with major problems.
Here, depending on the requirements of each situation, you can have total control of the audio
interface, reduce levels, route inputs to any output or set the Master Clock values. The GO46
Control Panel has several windows. You can change windows by using the tabs in the upper left
of the Control Panel.
The functions and the positions of the control elements are generally identical between the two
platforms, Windows and Mac OS. The following example illustrations have been taken from the
Windows version of the Control Panel.
Digital Mixer
In the Digital Mixer page, you can control the digital mixer of the GO46.
If you are working with common DAW applications, you should also use the DAW for level control.
The advantage for doing this is that the settings are usually saved together with your project (song,
arrangement etc.)
ANALOG IN / DIGITAL IN
Here you can control the levels of analog input channels in the ANALOG IN column and digital
input channels in the DIGITAL IN column. Use the faders to control the levels of corresponding
channels. The [MUTE] buttons can be used to mute the individual channels.
A separate fader is available for each mono channel. The individual channels can be joined using
the switchable stereo link function. To turn on/off the stereo link function, click the [PAIR] button.
While the stereo link function is active, faders and mute operations are linked.
When recording a mono input signal such as a guitar, the [MONO] button is useful. When this
button is active, the input signal will remain in mono, but the monitor sound will be in stereo.
DIGITAL IN is grayed out until a signal is applied to the digital input and the MASTER CLOCK
under “Output & Settings” (page 21) is set to [EXTERNAL].
