Crown II Manuals

POLAR PATTERN T he Crown® Sound Grabber II is an updated version of the original Sound Grabber. It utilizes the same Pressure Zone Microphone® technology in which sound waves reinforce themselves in the area nearest a fl at surface, usually referred to as the boundary. Top recording engineers all over the world are using professional versions of the Crown PZM® (Pressure Zone Microphone) to improve the quality of their recordings. The Sound Grabber II is one version of that technology, designed to meet the needs of the home or business recordist and bring the benefi ts of PZM technology within the reach of many more people. Because of this new technology, Sound Grab- ber II offers you the opportunity for vast im- provement in the quality of your recordings. The Sound Grabber II will pick up sounds at distances you never thought possible and it will pick them up with a clarity that other microphones, because of the limitations of their construction, simply cannot match. The Sound Grabber II does not need to follow the action, since it has a wide-angle pickup pattern. So long as the mic “sees” the sound, in whatever direction or angle, it will pick it up clearly; it does not need to be between you and the other person. Speakers or vocal- ists can move freely around the Sound Grab- ber II without their tone quality changing. For your greatest enjoyment of the Sound Grabber II, we urge you to read these instruc- tions thoroughly so you can be familiar with this new technology. Installing the Battery The Sound Grabber II is powered with an alkaline 1.5 volt AAA battery. One is furnished with the microphone, but it must be inserted into the microphone. Your battery will supply the needed power for the microphone for at least six weeks and possibly much longer. To install the battery open the cover (see Fig. 1) and insert the AAA battery. Please orient the battery as shown.

One microphone should be able to pick up groups of twelve or less at distances up to 5 feet. Larger groups may require additional mics depending on the distances involved. See Fig. 4. The Sound Grabber II shold not be covered with papers or books, as this could make the sound muffl ed. Interviews can also be miked with the Sound Grabber II mounted on the ceiling or in an overhead light fi xture. Pulpits, Lecterns Because it lies fl at on any surface, the Sound Grabber II is ideal for picking up speech at a lectern or pulpit. It is invisible to the audience and can be placed anywhere on the surface so as not to interfere with any books or pa- pers. See Fig. 6. Cassette Recording The Sound Grabber II is equipped with an 8 foot cord with a 1/8” mic plug, 1/4” phone- plug adaptor, and micro phone-plug adapter. SOUND GRABBER II Should you wish to record a conference group which is meeting without a table, the Sound Grabber II could be placed on the fl oor in the middle of the group or on a wall. Double-faced adhesive tape can be used, pro- viding the wall fi nish will not be damaged. Interviews For two-person interviews, see Fig. 5. If the interview is being recorded on television, the mic can easily be positioned out of the camera range and still have excellent audio pickup. The Sound Grabber II will provide an output signal that will record easily on any standard cassette recorder. Because of the mic’s novel design, you probably will fi nd that your recorder performs better than it ever has before. Video For video recording with a fi xed camera posi- tion, simply plug the mic into the camera and position the mic as needed for the type of recording you are doing. If the camera will be moving, you can tape the mic to the front of the camera or ask an assistant to hold the mic. Stereo Recording Mount two Sound Grabber IIs head high on a wall or on the fl oor and about 3 to 10 feet apart, facing the performers. The mics should be 5’ to 15’ from the performers (see Figs. 7 and 8). Warranty Crown professional microphones are guar- anteed unconditionally against malfunction from any cause for a period of one year from date of original purchase. Please refer to the blister pack for more details. Fig. 6 Fig.8 Fig. 5 Service If the microphone does not function prop- erly, check that it is aimed correctly and is connected as described in this data sheet. If service is required, return the microphone in its original packaging to Crown Factory Ser- vice, 1718 West Mishawaka Road, Elkhart, Indiana 46517-9439.

Architectural & Engineering Specifications S T U D I O R E F E R E N C E S E R I E S Studio Reference II (120 V, 60 Hz models) The Crown® Studio Reference II power amplifier shall be a solid-state two- channel model employing multi-mode (AB+B) grounded bridge(TM) output circuitry with a variable impedance (VZ) power supply for each channel. The outputs shall be switchable as stereo, bridged-mono or parallel-mono modes of operation. The bridged-mono mode shall bridge the outputs to provide increased output voltage. The parallel-mono mode shall parallel the outputs to provide increased output current. The output impedance of each channel shall be less than 10 milliohms in series with less than 2 microhenries in stereo mode. The variable impedance power supplies shall reduce unnecessary voltage across the output devices by automatically switching to a parallel mode when less voltage is required by the output circuitry and to a series mode when more voltage is required. The amplifier shall contain protection circuitry which limits the drive level placed on the output devices before their SOA (Safe Operating Area) is exceeded. This protection circuitry shall calculate the instantaneous volt- age across and current through the output devices while factoring in their simulated junction temperatures to predict how close they are to their operating limits. This protection will be called “ODEP.” The amplifier shall contain controlled slew-rate voltage circuitry to protect it against radio frequency interference burnouts. It shall also be protected from current overload at its output stage. The slew rate of the amplifier shall be greater than 30 volts per microsecond in stereo mode. The amplifier shall temporarily go into a stand-by mode if its power trans- former becomes excessively hot and shall automatically resume normal operation once it has cooled to a safe operating temperature. Front-panel controls shall include an enable on/off switch and a detented input level control for each channel. Rear-mounted controls shall include a ground lift switch to isolate the signal ground from the chassis ground, a switch which selects between stereo, bridged-mono and parallel-mono modes of operation and a reset switch for the AC mains circuit breaker. Internal controls shall include an input sensitivity switch to select between 0.775 V, 1.4 V or a fixed voltage gain of 26 dB for full rated output. A Crown P.I.P. and P.I.P.2-compatible expansion connector shall be pro- vided behind an access panel in the rear to accept auxiliary input modules. It shall be fully compatible with the Crown IQ System. Front panel indicators shall include an amber power enable indicator, an amber ODEP protection system indicator for each channel which shall normally be illuminated to confirm the availability of reserve thermody- namic energy and which shall dim in proportion to limiting when the power demands of the output stages have been exceeded, a green IOC indicator for each channel, and a green Signal indicator for each channel which shall normally flash at moderate intensity to show the presence of an audio signal. The power amplifier shall meet or exceed the following performance criteria. Input sensitivity for rated output: 26 dB voltage gain (unbalanced). Rated FTC output in stereo mode with less than 0.1% THD: 355watts per channel (20 Hz to 20 kHz) into 8 ohms. Hum and noise: at least 120 dB (A weighted) below full rated output power. Phase response: +5 to –15 degrees from 20 Hz to 20 kHz at 1 watt. Frequency response: 20 Hz to 20 kHz, 0.1 dB at 1 watt into 8 ohms per channel in stereo mode. Damping factor: greater than 20,000 from 10 to 200 Hz into 8 ohms. Intermodula- tion distortion (SMPTE): less than 0.005% from full bandwidth power to 78 watts rising linearly to better than 70 dB at 20 kHz. Harmonic distortion: less than 0.02% at rated low-distortion 1 kHz power. The amplifier shall be safe when driving any kind of load—even highly reactive ones. The power requirements shall be 120 VAC at 60 Hz. At idle, the amplifier shall draw 90 watts or less. The amplifier chassis shall be constructed of steel with a durable black finish and shall be designed for flow-through fan-assisted ventilation from the front panel to the side panels. The amplifier shall have an aluminum front panel with super-gloss Imron finish and Lexan overlay. The dimensions of the amplifier shall allow for 19 inch (48.3 cm) EIA standard (RS-310-B) rack mounting. The amplifier shall be 7 inches (17.8 cm) tall, 16 inches (40.6 cm) deep behind the rack-mounting surface, and 2.75 inches (7 cm) in front of the rack-mounting surface. The amplifier shall weigh 56 pounds, 2 ounces (25.5 kg) and shall have a center of gravity approximately 6 inches (15.2 cm) behind the front panel. The amplifier shall be designated the Crown Studio Reference II.

Here are the equations used to calculate the data presented in Figure 1: The quiescent power draw is a maximum value and includes power drawn by the fan. The following equation converts power draw in watts to current draw in amperes: The value used for Power Factor is 0.83. The Power Factor variable is needed to compen- sate for the differnece in phase between the AC mains voltage and current. The following equation is used to calculate thermal dissipation: The value used for inefficiency is 1.00-efficiency. The factor 3.415 converts watts to btu/ hr. Thermal dissipation in btu is divided by the constant 3.968 to get kcal. If you plan to measure output power under real-world conditions, the following equation may also be helpful: AC Power Draw and Thermal Dissipation The information provided on this page is calculated data based on driv- ing both channels to rated output using the 1 kHz Maximum Average Power rating method. Other parameters used in calculation include a conservative idle current estimate of 90 watts and a conservative estimate of effeciency at 65%. Information is provided only for getting an idea of current draw and heat produced. Actual performance will vary depending on environment, pro- gram material, load, signal, and AC mains voltage and frequency. Values of calculated current draw are intended to represent average draw corresponding to the thermal breaker requriements that should be met to handle the amplifier as a load on the AC mains. Peak current draw with dynamic program material may be significantly higher. Thermal information is provided to assist with calculating air conditioning needs. The data here should not be construed as specifica- tions.
