The Infinity Omega speaker is a high-quality audio/video loudspeaker system designed to deliver exceptional sound performance. It incorporates advanced technology in its drivers, crossover network, and cabinet construction, placing it at the forefront of speaker design. This manual provides comprehensive instructions for installing, operating, and maintaining the Omega speaker to ensure optimal musical potential and long-lasting, trouble-free service.
The Infinity Omega speaker is engineered to reproduce audio with remarkable clarity, detail, and a balanced tonal quality across the entire frequency spectrum. It is an exceptionally revealing system, capable of highlighting both the nuances of music and any sonic anomalies present in the associated audio components. The speaker's design aims to provide a pure and open sound, making it suitable for discerning audiophiles.
A key feature of the Omega speaker is its adaptability to various amplifier configurations. It can be connected using a standard stereo amplifier, where a single length of speaker wire connects each speaker to its respective amplifier output terminal. For enhanced performance, the Omega speaker supports bi-amping, allowing two separate power amplifiers to drive different sections of the speaker's crossover network. In a bi-amp setup, one amplifier feeds the woofer section, while the other drives the midrange/tweeter sections, resulting in a purer and more open sound. Additionally, the speaker supports bi-wiring, where two parallel speaker wires connect to the amplifier's output for each channel, with one pair connected to the woofer terminals and the other to the midrange/tweeter terminals. This configuration increases the conducting area, potentially improving current delivery and overall sound quality.
The Omega speaker is designed to work best when driven by high-current amplifiers with adequate power supplies and rugged output stages. This ensures cleaner, better-defined bass response and minimizes the risk of damage from amplifier clipping, which can occur when lower-power amplifiers are overdriven. The speaker's ability to handle low impedance loads continuously is also a critical performance parameter.
To achieve the best possible performance, careful attention to installation and operation is crucial.
Speaker Placement: The positioning of the Omega speakers within the listening room significantly impacts their performance. For optimal stereo imaging, speakers should be placed at least seven feet (2 meters) apart and as far away as possible from walls and corners to minimize reflections that can cause sonic anomalies like hardness, smeared sound, and lack of bass detail. Experimentation with placement, even moving the speakers by small increments, is encouraged to find the ideal position that delivers full musical potential. Moving speakers inward generally improves the focus of instruments and vocalists, while wider placement might be necessary for larger rooms or distant listening positions. Angling the speakers inward (toe-in) can enhance midrange and high-frequency projection, but excessive toe-in should be avoided as it can reduce stereo imaging and front-to-rear depth. Maintaining the speakers on the same plane and at the same angle relative to the front wall is essential for consistent sound. Room corners, in particular, should be avoided as they can over-accentuate bass frequencies, making them inarticulate.
Adjustable Driver Levels: The Omega speaker features adjustable levels for its EMIT™ tweeter and EMIM™ midrange drivers. The EMIT tweeter can be set to one of three positions: boost, flat, or cut. Similarly, the EMIM midrange can be set to flat or cut. These adjustments allow users to fine-tune the speaker's acoustic output to match the specific characteristics of their listening room and personal preferences. For instance, rooms with hard, reflective surfaces (like glass) might benefit from the "cut" setting, while rooms with more sound-absorbing materials (like draperies) might require "flat" or "boost" settings. Users are encouraged to trust their ears and select the settings that provide the most pleasurable listening experience.
Absolute Phase: Maintaining absolute phase throughout the audio system is vital for proper speaker performance, ensuring that all individual drivers move in and out in the same direction simultaneously. This contributes to accurate instrument localization and natural bass reproduction. If any component in the audio chain (amplifier, preamplifier, or CD player) inverts the audio signal, adjustments to speaker wiring may be necessary to restore absolute phase. If an amplifier is known to be inverting, reversing the polarity of both speakers (positive to negative, negative to positive) is recommended. However, it is crucial to maintain the left and right channel integrity.
System Control Settings: When operating the audio system, it is important to avoid setting equalizer, tone, and loudness controls to maximum boost, as this can strain the amplifier and potentially damage the speakers. The volume control setting itself is less important than the actual loudness level, which should be kept within safe limits. To prevent damage from loud transients, always turn down the system volume completely when changing inputs (e.g., from phono to CD or FM) or when handling records. Similarly, all equipment should be turned off before changing wires or pulling plugs to prevent transients from reaching the speakers.
Proper care of the Infinity Omega speakers will ensure their longevity and continued high performance.
Cleaning: The wood finish of the speakers can be cleaned using a soft cloth and a fine furniture oil. If using a spray cleaner/polish, care should be taken to avoid spraying directly onto the grille cloth. The grille may be vacuumed occasionally, but always use a low suction setting on the vacuum cleaner to prevent tearing the cloth.
Troubleshooting: The manual provides guidance for basic troubleshooting using the amplifier's two channels. If distorted sound is heard, checking each speaker separately can help determine if the fault is present in both channels. If it's in both, the issue likely lies elsewhere in the system. If the fault is in only one channel, reversing the amplifier outputs to the speakers (right-to-left and left-to-right) can help identify if the speaker itself is faulty. If the distortion moves with the channel reversal, the speaker is not the source of the problem. For persistent issues or if the source of trouble cannot be identified, consulting an authorized Infinity dealer is recommended, as they are audio specialists equipped to provide assistance.
Acoustic Feedback Management: Acoustic feedback, characterized by boomy bass or excessive bass driver movement, can occur when speaker vibrations reach the turntable and tonearm, creating resonance that feeds back into the electronics. To mitigate this, the turntable should be placed on a heavy, solid support as far away from the speakers as possible. Shock-mounted bases can also help reduce vibration pickup. CD players, which are also susceptible to vibrations, should be mounted on solid supports or on four rubber/plastic legs with controlled elasticity to acoustically isolate them.
By following these guidelines for installation, usage, and maintenance, owners of the Infinity Omega speaker system can maximize their listening pleasure and ensure the long-term reliability of their investment.
