Electro voice q66 manual

The output devices have a maximum junction temperature of o C o F , so high operational temperatures present no problems. The output devices are mounted directly to the heat sinks without mica insulators to ensure better dissipation of heat. The Q66 has sophisticated protection circuits that guard it and the load from problems. Protection circuits guard against overload, over-temperature, shorted outputs, radio-fre- quency interference and dc faults. The output devices are protected against damage from the reverse feeding of electrical energy back EMF from the load and are switched on via relays to avoid transients which could damage speakers.

The Q66 has built-in limiters to protect speakers from the deleterious effects of amplifier clipping. The Q66 has electronically-balanced XLRtype input and signal output connectors that allow easy, problem-free connections and signal routing.

The amplifier has an input. There are separate output connectors for channels, A and B, and for the bridge mode. The bridge mode connector is sealed with a plastic cover to prevent connection errors. To prevent ground loops from occurring, the Q66 is equipped with a ground-lift switch. When the amplifier is operated in a rack with units of different ground potential, the switch may be adjusted to eliminate hum. Separate potentiometers on the rear panel of the Q66 allow easy regulation of gain.

There is easily readable nomenclature to ensure easily repeatable control settings. The Electro-Voice Q66 is an excellent choice for high-quality professional sound system applications which require excellent sound quality, speaker protection and the highest level of construction quality and long-term reliability. Q66 Stereo Power Amplifier. The power amplifier shall be a dual-channel model of solid-state design employing highpower output devices in a true-complemen- tary-symmetry output circuit.

The amplifier shall contain sensing circuitry to provide protection for the output transistors against overtemperature, excessive output voltage, shorted loads, excessive phase shift and back-EMF current. Rearmounted input connectors shall include a 3- pin female XLR-type connector wired in parallel with a male 3-pin XLR-type output connector for signal routing.

Front-panel indicators shall include power on, a protection indicator and separate signal present and limiter indicators for each channel.

Front-panel controls shall include a power on switch. The power amplifier shall meet the following performance specifications: rated output power from , Hz at less than 0. THD, each channel watts into 8 ohms, watts into 4 ohms and watts into 2 ohms. See also: Owner's Manual. Previous Page. Next Page. Electro-Voice Q44 Owner's Manual 14 pages.

Features and Description. Responsibility of the User. Controls, Indicators and Connections. Operating Voltage. Mains Switch. Audio Input Cabeling. Volume Control. FAN Cooling. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintance servicing instructions in the literature accompanying the appliance.

Do not use this apparatus near water. Clean only with a dry cloth. Do not cover any ventilation openings. Do not install near heat sources such as radiators, heat registers, stoves, or other apparatus including amplifiers that produce heat. Do not defeat the safety purpose of the polarized or the grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong.

The wide blade or the third prong are provided for your safety. I the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus.

Use only with the cart, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. Unplug this apparatus during lightning storms or when unused for a long period of time. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as powersupply cord or plug is damaged, liquid has been spilled or orbjects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.

Do not expose this equipment to dripping or splashing and ensure that no objects filled with liquids, such as vases, are placed on the equipment. To completely disconnect this equipment from the AC Mains, disconnect the power supply cord plug from the AC receptacle.

The mains plug of the power supply cord shall remain readily operable. To reduce the risk of electric shock, do not perform any servicing other than that contained in the Operating Instructions unless you are qualified to do so.

Use of a mains separator transformer is mandatory during maintenance while the appliance is opened, needs to be operated and is connected to the mains. Switch off the power before retrofitting any extensions, changing the mains voltage or the output voltage. The minimum distance between parts carrying mains voltage and any accessible metal piece metal enclosure , respectively between the mains poles has to be 3 mm and needs to be minded at all times.

The minimum distance between parts carrying mains voltage and any switches or breakers that are not connected to the mains secondary parts has to be 6 mm and needs to be minded at all times.

Replacing special components that are marked in the circuit diagram using the security symbol Note is only permissible when using original parts. Altering the circuitry without prior consent or advice is not legitimate. Any work security regulations that are applicable at the locations where the appliance is being serviced have to be strictly obeyed.

This applies also to any regulations about the work place itself. All instructions concerning the handling of MOS-circuits have to be observed. The Wheelie Bin symbol found on the product or in the manual indicates that this product must not be disposed of with other waste. Arrangements are made with the dealer where you purchased the equipment from, for the returning of all unusable equipment at no cost , to the factory in Straubing, for environmental protective disposal.

Thank you for choosing Electro-Voice Q series amplifier.
