OMICRON ISSUE 2 DEC ‘98 CLASSÉ AUDIO OMICRON POWER AMPLIFIER OMICRON OWNER'S MANUAL
OMICRON ISSUE 2 DEC ‘98 CLASSÉ DESIGN PHILOSOPHY 1. REPEATED LISTENING DESIGN SESSIONS: Fine tuning of sound by exchanging and mixing of parts (transistors, capacitors, wiring, PCB boards etc.), and adjusting many specific operating voltages within proper engineering ranges, producing an overall sonic recipe giving the most natural harmonic realism of music typical of instruments in a live performance. 2.

OMICRON ISSUE 2 DEC ‘98 UNPACKING & SET-UP Your CLASSÉ OMICRON power amplifier is packed in high density, semi-rigid foam placed in a special Fiberglas case. To remove the unit, put the fibreglass case with the Classé lettering right side up. Unlock the four (4) case locking devices by first lifting the tabs, and turning them fully counter clockwise. Then, pull the tabs; the locking devices will pivot downwards. You can now remove the large top portion of the case.
OMICRON ISSUE 2 DEC ‘98 GENERAL CONNECTIONS A.C. LINE Insert the 2 linecords into the A.C. receptacle on the rear of the unit. PLEASE MAKE SURE YOU HAVE PREVIOUSLY HOOKED UP THE SPEAKERS AND PREAMPLIFIER TO YOUR AMPLIFIER BEFORE CONNECTING THE AC POWER CORD TO THE AMPLIFIER. IMPORTANT NOTE CAUTION: SAFETY INSTRUCTIONS DISCONNECT THE 2 AC LINE CABLES BEFORE MAKING ANY OTHER CONNECTIONS. "FLOATING THE GROUND” OR DEFEATING THE GROUND ON A 3-PRONG LINECORD MAY CREATE A SHOCK HAZARD.
OMICRON ISSUE 2 DEC ‘98 STEREO (CONTINUED) DO NOT OVERTIGHTEN the output connectors. When powering up the OMICRON in stereo mode, the left channel LED will blink for approximately 20 seconds, when the sequence is completed, the LED will turn SOLID RED. Then, the right channel LED will also blink for approximately 20 seconds and will also turn solid red once it has completed its turn on sequence.
OMICRON ISSUE 2 DEC ‘98 MONO OPERATION As stated above, either the regular or balanced inputs can be used in stereo or mono. Connect a single interconnect, either regular or balanced, to the left channel input of each amplifier. See the "Mono" section above for complete details. NOTE: Neither the Stereo-Mono switch nor the REGULAR/ BALANCED switch will operate while the amplifier is turned on.
OMICRON ISSUE 2 DEC ‘98 CONNECTIONS FOR REGULAR OR BALANCED INPUTS: The CLASSÉ OMICRON power amplifier is equipped with both regular and balanced inputs. Either one may be used SEPARATELY, BUT NOT SIMULTANEOUSLY. The balanced inputs must be connected to a preamplifier which has balanced main outputs. Balanced interconnects with "XLR" connectors are also required. Regardless of the amplifier inputs used, stereo or mono operation is possible on the OMICRON.
OMICRON ISSUE 2 DEC ‘98 BALANCED INPUTS (CONTINUED) again, the circuit will then engage. For use with balanced preamplifiers other than Classé, the wiring of the 3-pin XLR connectors must be matched to that of the CLASSÉ OMICRON which is wired as follows: PIN 1: GROUND PIN 2: POSITIVE (NON-INVERTED) SIGNAL, “HOT” PIN 3: NEGATIVE (INVERTED) SIGNAL All Classé preamplifiers and amplifiers are configured as above. Some preamplifiers from other manufacturers have PIN-3 set as the positive or “HOT” side.
OMICRON ISSUE 2 DEC ‘98 PROTECTION CIRCUIT A special circuit in the Classé OMICRON continuously monitors the output audio signal to detect output overload, clipping or DC content. In addition, each channel has two front end supply voltage fuses, located on the front end voltage regulation board, to protect the input circuitry from damage due to overload. There is a green LED for the negative voltage supply and a red for the positive.
OMICRON ISSUE 2 DEC ‘98 IR OUT and IN: The OMICRON may also be turned on and off using our SSP-75 Surround Sound Processor, utilising the IR OUT and IN jacks. Several amplifiers may be turned on automatically in sequence or all at once, depending upon the configuration of the jumper settings in the amplifier. Please contact your dealer for set-up specific to IR operation.
