Positive Grid RIFF User manual

OUTPUT JACK
This stereo jack provides a mix of the audio being
played back along with the input signal – depending
on the input volume set by the RIFF DIRECT parameter.
Use the appropriate cabling to connect this output to
your monitoring system, if desired. This signal is
identical to the jack signal.
USB
The USB connection establishes a two-way audio
connection between RIFF and your computer, and also
provides RIFF with the power it needs. The display will
indicate RIFF is connected and ready to use.

Meet RIFF.
Your RIFF is a handy recording interface designed specifically for the guitarist and
bassist. It connects directly to your PC, Mac, or Apple iOS device via USB. The design
is intuitive and uncluttered, providing quick access to all features. Extras include direct
signal monitoring that allows latency-free recording. Plus, you’ll even find a variety of
preset guitar tones. So let’s get started.

Getting Connected.
HEADPHONE OUTPUT
The audio signal present at this jack is identical to the
OUTPUT jack signal. This 3.5mm (1/8") stereo jack can
accommodate headphones rated from 16 Ohms to 64
Ohms.
INPUT
Plug your guitar or bass directly into this jack.
Selecting RIFF as the Input on your
Computer.
In general, if you connect RIFF to your computer before
launching your recording software, it will automatically
recognize RIFF and select it as the audio input source. If
not, you will have to choose it manually. For Mac, open
System Settings and select Sound. Click on the Input tab
and choose RIFF (Positive Grid). PC users will need to
open the Control Panels and select Sound. Click on the
Recording (input) tab and select RIFF (Positive Grid).
Selecting RIFF as the Output.
Depending on your setup, you may or may not want to use RIFF as the output device. If you have an existing
computer music rig that is already connected to your studio monitoring system, you may want to continue to use
that system. Using RIFF is ideal if you are working with headphones or a personal monitoring system.

• TONE 1: MODERN
This option adds a mild amount of compression to
the Direct signal for a more consistent sound.
• TONE 2: TRANSPARENT
Selecting this option will enhance the low and high
frequencies to create an authentic full-range sound.
• TONE 3: OLD SCHOOL FAT
This option adds a boost to the midrange
frequencies, creating a chunkier, fatter sound.
• 0: OFF
No TONE is applied.
Using the Controls.
1. DISPLAY
The display shows the current parameter (indicated by a box
around the parameter name) and its value (shown by the two
digit display in the center of the screen). The left side of the
screen shows a vertical Input Level meter; the right side of
the screen shows a vertical Output Level meter.
2. INDICATOR LIGHTS
Just below the display are three indicator lights.
• CLIP: When an input signal is present, this LED will be
green. Red indicates that the maximum level has been
exceeded and clipping has occurred. Lower the input level
if this indicator is frequently red.
• DIRECT: This blue LED is a visual reminder that the value
of the DIRECT parameter is set to a value other than 0 (O).
• TONE: This amber LED is a visual reminder that one of the
preset TONEs is selected.
3. CONTROL KNOB
RIFF is operated completely via the Control Knob. Pushing
down on the Control Knob will advance the selected
parameter from INPUT to OUTPUT to DIRECT to TONE
and back to INPUT in a continuous loop. Rotating the
Control Knob changes the value of the selected parameter,
as indicated in the display.
Parameters.
INPUT (0 to 50)
This parameter sets the volume of the input signal. There is a
vertical Input Volume meter along the left edge of the display.
Remember that the CLIP warning LED can be aected by the
value of this parameter.
OUTPUT (0 to 50)
This parameter sets the volume of the output signal. There is
a vertical Output Volume meter along the right edge of the
display. Keep this level somewhat high to minimize noise.
Use the volume controls on your external monitoring system
to set a safe listening level.
DIRECT (0 to 10)
This parameter mixes the Direct, or dry, input signal with the
wet output of your recording software. By mixing in the direct
signal, you can record with zero latency when recording or
overdubbing new parts. While some software packages may
do this on their own, this is very convenient when using RIFF
alone with a laptop and headphones, for example. If the
DIRECT parameter is set to a value other than 0 (O), the
DIRECT indicator will light.
TONE (0, 1, 2, 3)
RIFF relies on DSP technology to create a number of preset
TONEs. These built-in TONEs were created to replicate some
of the most popular guitar eect pedals, making it simple to
get a great sound as you record (TONEs are only applied to
the input / Direct signal). Select the TONE parameter and
rotate the wheel to choose a TONE. When a TONE other than
0 (O) is selected, the TONE indicator will light.
