Warranty
We guarantee our products for a period of
twenty-four months. The warranty period
begins on the date of purchase.
Please provide your bill of sale in all cases
as proof of warranty; without it, repairs will
be undertaken only at the owner’s expense.
We reserve the right to satisfy all warranty
requirements regarding defects of workman-
ship or materials by means of repair or partial
or complete replacement of the product, at
our sole discretion.
Excluded from this warranty are defects due
to misuse (e.g. incorrect operation; mechanical
damage), abuse or “acts of God”. This war-
ranty becomes void in the event of tampering
by unauthorized persons or agencies.
To secure your rights under this warranty,
send the product with proof of purchase and
a precise description of the malfunction, at
your expense, either to SCHOEPS (if you are a
customer in Germany), or to our representa-
tive (if you are a customer outside Germany).
Prior to sending your defective product for
repair, please contact your local dealer or dis-
tributor for instructions. In exceptional cases
you can, by prior arrangement with SCHOEPS,
send the product directly to us from a foreign
country.
This warranty does not affect any contrac-
tual agreements which may exist between the
buyer and seller of the equipment.
This warranty is world-wide.
Declaration of Conformity
The CE-mark guarantees that all products con-
form to relevant standards approved by the
European Community. The products described
in this User Guide comply with current, relevant
standards when used with cables from SCHOEPS.
Relevant directives:
EMC Directive: 2004/108/EC
Relevant standards:
EN 55 103-1, -2 and those referred to by
them.
Verifying correct 48 V phantom powering
These measurements should be made at an
unused input. Reduce the channel gain to the
minimum to protect loudspeakers, etc. If micro-
phones are connected to other inputs at the
same time, no substantial difference should
occur in the results.
There are three methods:
Method 1
Measure the open-circuit voltage between
ground (pin 1) and either pin 2 or pin 3 of the
XLR input. Given the permitted tolerances,
this voltage should be between 44 and 52 VDC
for P48. Then, measure the short-circuit current
between ground (pin 1) and either pin 2 or
pin 3 of the XLR input. Given the permitted
tolerances, this current should be between
5.9 and 8.5 mA DC for P48.
Note: Well-designed phantom power supplies
must tolerate at least a temporary short circuit
without damage; an unbalanced connection
(which is occasionally necessary) would cause
the same current to be drawn. To be safe,
however, do not leave the short circuit in place
any longer than necessary.
Method 2
Measure the DC voltages on the modulation
leads with a microphone connected, e.g. by
opening the connector shell of the cable. The
two voltages (from pin 2 and pin 3 to pin 1)
must be identical. They should fall in the range
from 33.5 Volts to 40 Volts.
Method 3
Use a SCHOEPS PHS 48 tester. Plug it in; if the
LED glows and stays lit, all is well.
