gml gml2032 Manual De Usuario

A.  City of Los Angeles, UL, and CE standards require these safety statements.

B.  The Grounds terminal block gives a common point of continuity to the electronics ground (upper) and

the chassis ground (lower).  Normally these terminals are tied together with the Ground Strap.

C.  An IEC-type socket provides connection to AC mains power (50 / 60 Hz) via an external power cable.

A 6-ft. power cable ships standard with all new units.

D.  Protecting both the power supply fuse and a spare, the safety-interlocking Fuse Holder prevents fuse

removal with an IEC plug inserted.  Replace with 500mA (110V) or 250mA (220V) Slo-Blow 250V-
rated fuse (5mm x 20mm package).  NOTICE: Repeated fuse failure may indicate internal fault.
Request service as per Contacts section of this manual.

E.  Allowing worldwide operation, the Voltage Select switch sets the internal power supply for the correct

AC mains line voltage, either 110V or 220V.  Gently rotate the switch using a small flat-head
screwdriver; the voltage setting is indicated by the small triangle.  WARNING – A mismatch between
AC line voltage and setting of the Voltage Select switch may cause permanent damage.

F.  Internal supply voltage regulator mounting screws should NOT be shorted nor loosened, as this could

impair unit performance and/or cause irreversible damage.

G.  Uniquely assigned, the GML Serial Number Tag contains a permanent imprint of the serial number.

H.  The Output XLR provides a professional interconnect to external devices.  DC Servo corrected, direct

coupled, and unbalanced (pin 2 “hot”), this yields the equalizer output.

I.  Active when Insert is engaged, the Insert In XLR is a balanced feed to the equalizer input.

J.  Regardless of Insert status, Insert Out monitors the preamp output, post-filter.  This XLR is DC Servo

corrected, direct coupled, and unbalanced (pin 2 “hot”).

K.  The Input XLR applies signal to the preamplifier when MIC is selected on the Source switch.

L.  CE (European Electromagnetic Compatibility) marking indicates full compliance with EN 55013:1990

(Electromagnetic Disturbance, Sects. 3.2, 3.5) and EN 55020:1988 (Electromagnetic Compatibility,
Sects. 4.3, 5.4, 6.2, 7.0, 8.0).

M.  The Ground Strap normally connects electronics ground and chassis ground; however, in certain

situations it may be advantageous and/or necessary to keep these ground references independent (to
eliminate ground loops in some installations, for instance).

N.  An Output Warning notice reminds users of the inherent danger and permanent damage associated

with shorting the output.  Normally, pin 2 is wired as the “hot” output pin.
