VANDERSTEEN M5-HPA Preliminary Owners Manual

-If the amplifier came in from the cold (less than 50 degrees Fahrenheit) let the entire assembly come to room temperature to
minimize condensation. FOR STABILITY REASONS USE SPEAKER WIRES THAT ARE 4 FEET OR LESS IN LENGTH!
-Do not move the amplifier or power it up without the cover on with all screws in place or the PCB could be damaged.
-UNPLUG THE M5-HPA FROM AC FOR 3 MINUTES BEFORE CHANGING THE ROTARY HIGH-PASS SWITCH TO A DIFFERENT FREQ!

UNPACKING THE M5-HPA

-You have obviously opened the carton to find this owners manual.
-Remove the power cord and remove the top tray.
-Using the Speaker Output connector and the Logo Recess on the Front Panel lift the M5-HPA out of the shipping carton.
-Remove the Plastic Bag.
-Install the HRS footers with the ones marked with the Yellow Dot in the front two threaded inserts and the ones marked with Light
Blue Dot into the rear threaded inserts hand tight (it is very important to get the color coding correct).
-Locate the M5-HPA near the speakers directly on the floor without amplifier base except for a piece of 1 inch granite if desired.

PREPARING THE M5-HPA FOR OPERATION

-Remove the 14 screws attaching the cover and lift straight up and off (not necessary if the M5-HPA will be used in the 100Hz high
pass mode as they come set to 100Hz).
-Set the High-Pass Rotary Switch located approximately in the middle of the main circuit board (comes preset to 100Hz) for the
high-pass frequency desired. Example: QUATRO / QUATRO CT, MODEL 5, 5A,5A CARBON, SEVEN, SEVEN Mk II = 100Hz. Any
speaker while using the 2W, 2Wq ,SUB THREE or any other application requiring 80Hz high pass = 80Hz. A total of five settings are
available: 20, 40, 80, 100 and 200Hz. DO NOT CHANGE THIS SWITCH SETTING WHILE THE M5-HPA IS PLUGGED INTO AC POWER!
Reinstall the cover and its 14 screws. DO NOT TRY TO MOVE THE M5-HPA WITHOUT THE COVER INSTALLED AS IT IS AN
INTEGRAL PART OF THE CHASSIS' INTEGRITY AND DAMAGE TO THE PCB COULD RESULT.
-Hook up speaker cable maintaining proper polarity. A few words about speaker cables as they can be very expensive,
using the M5-HPA near the speaker sounds better because ones budget will allow a higher quality cable and bi-wiring if
applicable. Long Balanced interconnects cost less and cause less signal degradation as the input impedance is 200k. When doing
true bi-wiring it is best to connect both positive wires and both negative wires into one set of a sufficiently large Ring Lug
Connectors (available from your VANDERSTEEN DEALER). By removing the Knob of the Cardas speaker connector used on the M5-
HPA the Pressure Block can be removed allowing appropriate 1/4 inch Ring Lug to be installed. Reinstall the Pressure Block which
is indexed and will only go on one way.
-Plug in the provided power cord IEC-C20.
-Turn on the Circuit Breaker/Power Switch on the back of the M5-HPA. The left LED on the Front Panel should flash red and turn
green. If the M5-HPA has been off for any time, wait 20 minutes before trying to go to operate.
