Controls and Functions

AUDIOGRAM 6 Owner’s Manual

COMP Control

Adjusts the amount of compression applied to the chan-
nel. As the knob is turned to the right, the interface
automatically raises the compression ratio while adjust-
ing the output gain accordingly. The result is smoother,
more even dynamics because louder signals are atten-
uated while the overall level is boosted.

Avoid setting the compression too high, as
the higher average output level that results
may lead to feedback.

MONO/STEREO Switch

This switch allows channels 1 and 2 to be used either
as separate mono channels or as a stereo pair. When
set to MONO (

), channels 1 and 2 function as inde-

pendent mono channels feeding both the L and R STE-
REO OUT jacks

. When set to STEREO (

), input

channels 1 and 2 function as a stereo pair: the channel
1 signal feeds the L STEREO OUT jack and the chan-
nel 2 signal feeds the R STEREO OUT jack.

PEAK Indicators

The PEAK indicators light when the channel signal
reaches or exceeds clipping level. Note that signal lev-
els as indicated by the PEAK indicators are affected by
both the GAIN and LEVEL controls.
If a PEAK indicator lights, adjust the GAIN

and

COMP

controls to lower the level so that the indica-

tor goes out.

LEVEL Controls

Adjusts the level of the channel signal. Use these con-
trols to adjust the balance between the various chan-
nels.

POWER Indicator

This indicator lights when power is applied to the
AUDIOGRAM interface via the USB cable (supplied)
that connects it to the computer.

P48V (CH1) Switch/Indicator
(only for channel 1)

This switch toggles phantom power on and off. If you
set the switch on (

), the AUDIOGRAM supplies

phantom power to channel 1 MIC/INST jack (XLR-type)

. Turn this switch on when using a phantom-powered

condenser microphone.

• Be sure to leave this switch off (

) if

you do not need phantom power.

• When turning the switch on, be sure that

only a condenser microphone is con-
nected to the channel 1 MIC/INST input
jack. Other devices may be damaged if
connected to phantom power. This precau-
tion does not apply to balanced dynamic
microphones or instruments with the
phone jack, however, as these will not be
affected by phantom power.

• To prevent damage to speakers, be sure to

turn off power amplifiers (or powered
speakers) before turning this switch on or
off. We also recommend that you set the
MASTER LEVEL control to the minimum
position. Neglect of these precautions may
result in large noise bursts that may dam-
age your equipment, your ears, or both.

Level Indicators

These indicators show signal levels prior to the MASTER
LEVEL control

. The SIGNAL LED lights when a signal

is present, and the PEAK LED lights when the signal
reaches or exceeds clipping level. Adjust the input chan-
nel LEVEL controls

so that the PEAK LEDs flash only

briefly on occasional high-level peaks or not at all.

DAW Control

Adjusts the level of the signal received from Cubase AI
sent to the AUDIOGRAM STEREO OUT jacks

MASTER LEVEL Control

Adjusts the signal level sent to the STEREO OUT jacks

. This allows you to adjust the overall volume without

changing the relative volume balance among the chan-
nels.

USB Connector

Connects the AUDIOGRAM interface to a USB port on
your computer via the supplied USB cable. In addition
to transferring audio data between the AUDIOGRAM
interface and the computer, the USB cable supplies
power from the computer to the AUDIOGRAM interface.

When connecting or disconnecting the USB
cable be sure to turn the DAW control and the
MASTER LEVEL control all the way down.

Yamaha recommends that you use a USB
cable with a length of 1.5 meter or less.
