Next If your subwoofer doesn’t have an internal amplifier , you’ll definitely want to connect an amplifier to it. To do this, you’ll need your subwoofer, an amplifier, at least one set of RCA cables these are the red, white, and yellow jacks on a single cable , speakers , and speaker wires. First, you’ll want to think about where you’ll keep the subwoofer. Because the subwoofer is working mostly on the bass the low tones , it doesn’t require as much directional pushing as speakers do. Since you’ll have to run cables and wires between the subwoofer and other devices, you might want to keep it just a few feet from your screen. To get started with the actual hook-up, you’ll connect the subwoofer to the amplifier using the RCA cable.

An antenna tuner, (transmatch), doesn’t really TUNE your antenna OR ANY PART OF IT! Let’s hook one up in a typical HF station. In the block diagram below we have a typical Hf station setup consisting of: An HF Transceiver A Linear or power amp Low Pass Filter Swr/Watt Meter combo The Antenna Tuner A Dummy Load.

Many guitar amplifiers and small stereos come with amplifiers pre-attached to speakers, so there is no need to connect those. However, most high-end guitar amplifiers have speakers sold separately, or allow you to connect to speakers in addition to the one that came with the amp. Similarly, most high-end home stereos require you to connect the speakers to the amplifier manually.

Connecting a Speaker to a Guitar Amp Locate the speaker output jack on your guitar amp. Usually, this is a quarter-inch input hole, though some guitar amps also have speaker output jacks for Speakon cables or XLR cables. Most of the time, the speaker output jack is on the back of the amp.


A dipole is nominally a single band antenna. They will work on their 3rd harmonic, so a dipole cut for 40 meters will present a decent match to coax feedline somewhere in the 7 Mhz. It will not present a decent match to coax on any other bands. A tuner can be used to stretch an antenna to work on other bands, within limits.

Take a look at the block diagram above and notice where the antenna tuner and SWR meter are in relation to the flow of the RF signal coming from the transceiver. Your station may not use them You will notice that You just learned how to hook it all up! Just remember that our goal is to make the transceiver think all is well, and in order to “read” the SWR and Power out pertaining to “all is well”.

Most antenna tuners have an inductance rotary switch and two capacitors. In some antenna tuners the inductance switch is replaced with a continuously variable inductance, popularly known as a roller inductor. Let’s assume you’re using a tuner with an inductance switch, because they are the most common. Place both capacitor controls at their mid-range positions. Don’t trust the knob markers if this is your first experience with the tuner; if you are comfortable with it, remove the cover and turn the knobs until the moving capacitor plates are only half meshed with the stationary plates.

If the knobs are pointing to half scale, consider yourself lucky.

Supercardioid Shotgun A microphone’s directionality or polar pattern indicates how sensitive it is to sounds arriving at different angles about its central axis. The polar patterns illustrated above represent the locus of points that produce the same signal level output in the microphone if a given sound pressure level SPL is generated from that point. How the physical body of the microphone is oriented relative to the diagrams depends on the microphone design.

For large-membrane microphones such as in the Oktava pictured above , the upward direction in the polar diagram is usually perpendicular to the microphone body, commonly known as “side fire” or “side address”. Some microphone designs combine several principles in creating the desired polar pattern. Omnidirectional[ edit ] An omnidirectional or nondirectional microphone’s response is generally considered to be a perfect sphere in three dimensions.

In the real world, this is not the case. As with directional microphones, the polar pattern for an “omnidirectional” microphone is a function of frequency. The body of the microphone is not infinitely small and, as a consequence, it tends to get in its own way with respect to sounds arriving from the rear, causing a slight flattening of the polar response. This flattening increases as the diameter of the microphone assuming it’s cylindrical reaches the wavelength of the frequency in question.

Therefore, the smallest diameter microphone gives the best omnidirectional characteristics at high frequencies.

How to hook an integrated amp to a AV receiver?

If you have ever tried to use the 80 meter phone band for local communications on winter evenings, you probably experienced situations where under Km propagation was almost nonexistent. The group of friends that I talk with on 80 meters was plagued by these “winter doldrum” conditions so a few of us put up meter antennas to see if the situation could be improved. We discovered that, when the 80 meter band was essentially useless for short-haul propagation, the meter band provided good communication.

For this simple hook up guide we will just be hooking up a load cell with the HX amplifier, and showing how you would hook up four load sensors with a combinator board and the HX amplifier.

It shows on the picture by the two AC outputs 7 and 8. I cannot find a download for the manual so I cannot confirm that both of these AC outputs are milliamps but this is what it looks like from the data on their website. Will this damage the unit? The amp comes with FX loop but currently my new setup is running everything upfront. I only want to gate my drive pedals and vibe.

The pedals in use are as below: You want to set up a loop with the G String as follows: The output will drive your Strymon and Dyna Verb without any truncation of the delay or reverb and the output of these effects will feed the input of your amplifier. And to switch between just distortion to just preamp, do I have to hit two buttons or does turning off distortion automatically engage preamp?

Attempting to use an amplifier at an unstable load will damage the amp. Note that some high end car audio vendors intentionally underrate their amplifiers so that a 50×2 Watt amplifier 4 ohms really does produce x1 4 ohms. This is done so that car stereo systems using their equipment can enter car audio competitions in a lower Wattage category, giving them an edge over the competition.

Meanwhile, many low end manufacturers overstate the power of their amplifiers.

In the mid s large numbers of small FM transmitters, operating in the FM radio broadcast band ( MHz) appeared on the market. It started with a self-build kit from the Danish manufacturer Jostykit that allowed everyone to build a small FM transmitter for a few Euros.

It has been designed for operation on all amateur frequencies from 1. Three Eimac 3CPX A7 pulse rated ceramic-metal triodes configured in a grounded grid circuit allow for conservative operation at watts continuous carrier output. DO NOT operate this amplifier with the top or bottom covers removed. If there is any damage, notify the deliv- ering shipper immediately, fully describing the damage. The HV power transformer was shipped separately, as its weight would damage the cabinet in transit.

Page 7 Plug the first connector on the transformer into the mating one on the chassis wiring harness. It is keyed so that it cannot be plugged in back- wards.
