Setting up your turntables
1. Set the tone arms to the specific recommendations of the
cartridge used, such that the needle never leaves the record, but
not heavy enough that it heats up significantly. Both produce
poor tracking.
2. If the track plays backwards, try swapping the left and right
cables. The inputs from your turntables might be the wrong
way around. Left=white, Right=red.
3. Grounding is extremely important when using Scratch
LIVE
.
Make sure you have good connections from the ground wires
of your turntables to the grounding post of your DJ mixer.
All DJ mixers with turntable inputs have built in grounding
points for this purpose. If you do not ground your turntables
properly, the control signal will be noisy and the tracking of
the record position will be erratic. (See
signal threshold
on
the next page.
Tip: We recommend Shure M44-7 needles for use with Scratch
LIVE
, due to their high output volume, excellent tracking
and low record wear.
Starting the software
Close all other programs on your Mac or PC. When you load
Scratch
LIVE
for the first time, you will see the screen below.
Troubleshoot: The TTM 57SL mixer is not recognized
It takes five seconds for Scratch
LIVE
to detect the TTM 57SL.
The mixer can be unplugged at any time; you do not need to exit
Scratch
LIVE
before disconnecting the hardware. In some situa-
tions you might need to “wake up” your USB port by unplugging
and re-plugging in the TTM 57SL for Scratch
LIVE
to recognize
it. Use the supplied USB cable — longer lengths are not recom
-
mended. On some Windows machines each USB port is treated
separately, so you will need to install the driver separately for each
USB port.
