K Series step-up procedure
How to use Powersoft K Series Step-Up card to upgrade the amplier power output
Powersoft K4 to K10 share the same hardware platform: the
power output is rmware limited. A Step-Up card allows to
upgrade a K4, K6, K8 to the closer higer model (from K4 to K6,
from K6 to K8, from K8 to K10).
K3 and K20 have dedicated hardware platforms and can not
be upgraded.
Each Step-Up card can upgrade just one step per K Series (K4,
K6, K8) amplier; once the procedure is performed the Step-
Up card is useless and can not be re-used. It is not possible to
downgrade an upgraded K Series amplier nor transfer an upgrade
to another amplier.
It is possible to upgrade an amplier until K10 top performances
are achieved, so more than a Step-Up card is necessary to upgrade
K4 or K6 to K10; please remember that any subsequent upgrade
can be performed only after having nalized the rst step-up
through the K Series website, as detailed below here.
Step-Up process must be nalized through registering the
upgrade on http://www.powersoft-audio.com/en/k-series-step-up.
If the upgrade is not registered within 50 working hours after
the Step-Up has been used – the so called temporary Step-Up
period – the amplier will automatically return to the original
setting, losing the upgrade: a new Step-Up card have to be
purchased in order to newly upgrade the amplier.
The Step-Up functionality is available for any existing K Series
amplier hardware revision, however a proper rmware version
(3.8.5 or higher) is strictly required.
For this reason, please check if your amp is running a compatible
rmware revision, following these simple steps:
f Power on the amplier
f Press the MENU button
f Scroll down to SETUP and conrm with OK
f Press OK to enter the HARDWARE INFO
f Display will show amplier model and serial number
f Press MORE and the following info will appear:
KFRONT: X.Y.Z–B
KCNTRL: X.Y.Z–B
KDSP: X.Y.Z–S [if KDSP optional board is NOT
installed on this row you will
read KDSP: N.A. (not available)]
where X.Y.Z is the rmware version, B is build number and S
(4 digits) is the SHARC rmware version in case the KDSP op-
tional board is installed.
If either KFRONT or KCNTRL versions are older than 3.8.5
you need to perform a rmware update via a dedicated Firmware
Update Smart Card. Please refer to your local distributor/dealer
to receive a rmware update Smart Card.
1 Step-Up Procedure
1. Power on the amplier; if the amp is brand new keep it on for
at least 15 minutes before proceeding to next step.
2. Hold the Step-Up card with the Powersoft logo faceing up
and the electrical contacts faceing down: insert the Step-Up
card softly into the smart card slot just above the display of
the amplier. Be sure to completly insert the card reaching
the end of the slot. “Checking upgrade card” should appear
on the display; if no messages are displayed, please consider
that either the card does not ll completly the slot or the
electrical contacts could be dirty: try to extract and insert
the card again.
3. After checking the Step-Up card, the amplier’s display
shows the message “Upgrade available!” and requests
to conrm the upgrade. Depending on the model the
message “K4 K6?”, “K6 K8?” or “K8 K10? ” is shown.
Push the OK button or cancel by pressing the BACK button.
4. Conrming the Step-Up with OK will start the upgrade: after
few seconds “Upgrade Complete” appears on the display.
The amplier automatically restarts: it switches off and then
back on.
At the end of this process the amplier behave as the closer
higher model – K4 will become a K6, K6 will become a K8,
K8 will become a K10 – offering immediatly larger power handling
(temporary Step-Up period).
