Audio Phase Detector* Designed and Built by Charles Kitchin of Analog Devices Norwood. MA. Audio Phase Detector For the owners of a modest stereo system utilizing one speaker per channel. Phasing the speakers is a relatively easy task. By connecting the speakers by polarity dots or switching the leads from one speaker and listening for the most solid bass response and best stereo centering, proper phasing is accomplished. However. If more than one amplifier is used such as in biamp and triamp systems, phasing can become a horror show. Unless the amplifiers are identical(i.e.the same phase shift in each) wiring up the speakers by polarity will not work. The problem is compounded by the electronic crossover which may, or may not, have the bass, midrange, and/or treble outputs in phase with another. Also microphones and audio lines are difficult to phase correctly. Device Description. A simple and inexpensive solution to this problem is to send a coded signal through the system. It is picked up on a portable receiver which can listen to each speaker individually and indicate its phase relative to the other speakers in the system. Such a device is the audio phase detector. The coded signal is a sawtooth waveform generated by an integrated circuit voltage to frequency converter(a voltage-controlled oscillator) The Analog Devices AD537. A sawtooth waveform is connected to the line input jack of an amplifier, amplified, and the speakers will produce the waveform into a sound wave picked up by a microphone on the receiver. The air mass between speaker and receiver acts like a capacitor and differentiat

R, L-R, L+R, Precision 10 dB. 1.0 dB, and 0.1 db Step Attenuators, High Level of RF Shielding, The AG-51 Audio Generator contains a low distortion 20 Hz to 200 kHz sine wave generator. An SMPTE standard intermodulation signal generator and a fixed frequency sine wave generator at 3.15 kHz for wow and flutter tests. Signal outputs are simultaneously available at levels ... moreof up to +20 dBm(equivalent sine wave power for complex signals) at separate left(L OUT) and right(R OUT) output connectors. Outputs may be selected for left(L) only, right(R) only, left and right in phase(L+R) and left and right in phase opposition(L-R) Fully balanced or unbalanced outputs at impedance levels 150 ohms or 600 ohms are front panel selectable. Three precision attenuators(10, 1.0 and 0.1 dB) provide a dynamic range of 99.9 dB in 0.1 dB steps. Attenuator dials display the output level directly in dBm in the 150 ohm source impedance configuration. Automatic output leveling circuitry with a built-in self-test feature provides a constant output level thereby eliminating the need for output metering. In the TEST mode the generator output level is reduced to zero, a useful feature during noise measurements. The time constant of the leveling control loop is determined by a front panel switch. For rapid frequency response measurements. This switch is set to the FAST RESPONSE position. This feature enables the operator to evaluate frequency response of the device under test(amplifier, filter, etc. with a manual sweep of the frequency dial and multiplier switch

The best vintage Bruel & Kjaer 1022 Beat Freq. Audio Oscillator 1022 Vacuum tbs!
The best vintage Bruel& Kjaer 1022 Beat Frequency Audio Oscillator 1022 on Vacuum Tubes! For sale is a one of the best vintage audio oscillators– a Bruel and Kjaer 1022 beat frequency oscillator for electrical and electro acoustical measurements. The unit is refurbished and tested in all modes. Guaranteed to work well. It sells with the original power cord. The 1022 is an ideal bench oscillator for those who service and repair loudspeakers and electronic audio equipment. The 1022 allows full frequency sweep from 20 Hz to 20 kHz in just one turn of a dial. The 1022 has low harmonic distortion(below 0.05% The output can be either from an attenuator(from 0.12 mkV max to 12 V max) or from a power amplifier/ transformer(~ 4 watts) That can be switched to different load impedances: 6 Ohm(4V max) 60 Ohm(12V max) and 600 Ohm(40 V max) and 6000 ... moreOhm(120 V max) Having such a verity of output impedances allows the user conveniently diagnose various loudspeakers. The 1022 can generate warble tones with adjustable modulation frequency and frequency deviation. It also can operate with compression. The compression mode is useful when testing the responses of microphones. The output signal from the reference microphone is fed to the compression output of 1022. While the output signal of 1022 is fed to the loudspeaker that generate the test signal. In this mode the setup maintains a constant sound pressure near the reference microphone. By putting a microphone under test near the reference microphone it is possible to test its frequency response accurately, even though the loudspeaker of the test setup does not have the ideally flat frequency response. The 1022 can work together with B&K level recorder 2305 or 2307 in order to record the results of frequency response sweeps. The 1022 dimensions are 5” W) x 18.9” H) x 7.9” D) and weight is 31 lbs
Very Early Hewlett Packard 200B Audio Oscillator Working 1940’S
This is a Very Early Hewlett Packard 200B Audio Oscillator. It is working as seen from the pictures. Notice the actual waveform. The paint is worn and the cord is dry and cracked. I do see at least one non original filter capacitor. This is amazing that the unit is still working. It will surely need further restoration due to age. Looks like this unit may have been owned by WDSU. The first TV station in Louisiana. Here is some info I found about this unit and Bill Hewlett: Bill's prototype became the HP company's first product the HP 200A. As shown in the wiring diagram below, two options with different frequency ranges were available: the 200A and 200B. A small modification of 6 resistors values resulted in different frequency ranges 35 to 35,000 cps for the 200A and 20 to 20,000 cps for the 200B. All other specifications are common ... morefor the two units. A two-stage power amplifier with transformer-coupled output delivers 1 Watt into a 500 ohm resistance load. The output voltage is controlled ahead of the output amplifier from a front panel level control. The total harmonic distortion is lower than 0.5% The HP 200B with rounded corners shown in this photo was hand built, probably in the second garage( 481 Page Mill Road) in 1940, and may have been handled by Bill and Dave themselves. It is so old, they do not even have a HP company logo yet. Units with this particular case style are very rare today. If for any reason there is a problem whether it is with the item. Shipping or communication, please contact me the seller whether the item is new or used if there is a problem; I am sure we can work out a solution.

HP 200C Antique Hewlett Packard Audio Oscillator from 1940's
Hewlett Packard Model 200C Wide Range Audio Oscillator(S/N# A2203) Item is in FAIR overall physical condition and needs a FULL restoration. This item was Hewlett Packard’s 3rd series of their original product and the 200C offered a 4th range that allowed the unit to cover 20-200KHz in 4 ranges. We believe that this unit is an early production unit from the early 1940’s and it appears to be complete. The power cord was old and cracked with bare wire exposed so we cut it off. There is light surface rust on the unit since these early units had very thin paint but with a little steel wool cleaning and some good Grey enamel paint. This unit could be made to look very nice. The last time it was calibrated according to a calibration sticker on the side of the unit was in the very early 1960’s. Due to the early Serial number A2203, This unit would ... moremake a nice addition to someone’s antique Hewlett Packard test equipment collection and would be a simple, fun restoration project. This item came from the estate of a radio collector who valued equipment such as this. This item was very well designed and is beautifully constructed with excellent quality components and it would make a nice addition to someone’s workshop or laboratory. To insure that the Audio Oscillator arrives in good condition it has been very carefully packaged with excellent packaging materials in a very sturdy 21 X 16 X 13 inch Box with a packaged weight of approximately 30 pounds and it ships from Zip Code 92603.

PayPal Will ONLY be accepted from users with a CONFIRMED ADDRESS* AND* the Item MUST ship to that SAME ADDRESS.
