Many makers and engineers got into engineering through audio. Whether it be building a guitar pedal or modding the power amp in your home theater, working with audio components is a fun way to use your engineering skills.

This wishlist presents some of the tools and parts you need for working with audio. Audio is a broad topic, so this wishlist is a general overview of analog audio components. We'll get specific in later articles.

Tools
For audio related building, here are some handy tools to have on your bench!

Oscilloscope
An oscilloscope is your best friend for audio work. They can be used to check frequency response, distortion characteristics, and everything other specification that is important to an audio signal.

Multicomp Pro Oscilloscope

Function Generator
Audio work is all about frequencies. A function generator sends different kinds of waves at different frequencies so you know if your build is responding the way you want it to.

Multicomp Pro Function Generator

Multimeter
Multimeters are essential for every kind of electronics work; audio is no different.

Multicomp Pro Multimeter

Speaker Dummy Load
Since we can't use speakers for our testing, all that power needs someplace to go. A dummy load simulates a speaker in your circuit without blowing your head off with volume. A dummy load can be built with a high wattage resistor at the desired resistance, usually 4, 8, or 16 ohms for speakers.

Vishay Dummy Load

Contact Cleaner
If you're repairing equipment that has scratchy pots, many times, a bottle of contact cleaner is all you need. Drip a little bit into the pot and exercise it; your noise issues will often disappear.

Helping Hands
You've probably already got a nice soldering station, so we won't get into soldering equipment, but with any soldering project, because we don't have six arms ourselves, a set of helping hands is very valuable.

Duratool Helping Hands

Components
Audio circuits use a wide variety of analog components to keep that audio sounding good.

Transistors
Transistors are typically used to amplify audio signals, and sometimes distort. Different types of transistors have different characteristics, whether they are BJT, MOSFET, JFET, or even silicon or germanium.

Multicomp Pro Transistor

Potentiometers
If you're putting any kind of analog controls on your new creation, you'll likely need pots or faders.

Bourns Potentiometer

Opamps
Opamps (operational amplifier) designed to amplify signals and there's a wide range, from large and discrete, like the vintage API 2520 (and its descendants), to surface mount. Opamp design has come a long way and newer opamps, like the AD797, boast near zero distortion and noise, although classic opamps like the TL072 and 5532 still offer great sounds in the right circuit.

AD797 Opamp

Transformers
Transformers do a whole lot of things in an audio circuit; impedance matching, balancing, stepping up or down, etc. Because they only transmit audio signals, transformers also provide an important benefit: isolation.

Hammond 119DA Transformer

Power Supply
Your opamps and transistors need to be powered, so chances are you'll need a good DC power supply. Op amps typically take somewhere in the range of +/-16V, while a discrete transistor based circuit might require a 24V supply. If you're making a microphone preamp that supplies phantom power, you'll need to supply 48V.

Delta 24V Power Supply

Connectors
To get your audio signal in and out of your circuit, you'll need connectors.

Neutrik XLR Connector

Cliff 8-Way Spring Terminal

Speakers, Headphones, and Mic
Now the fun part! The most important tools for testing audio devices are your ears. Speakers, speaker drivers, and headphones are the most important tools once you're ready to test your design. Fingers crossed that you don't get a blast of loud feedback when you flip the switch!

There are several different types of microphones – large diaphragm condensers, small diaphragm condensers, dynamics, ribbons, and more, all designed for specific purposes. We’ve selected a lavalier because it’s a tiny inexpensive mic that is convenient for testing on the bench.

FMER SOL - SCHURTER presents new model 2300 A and variants

without Y-capacitors. SCHURTER is expanding its successful FMER

series of high-current filters with a model for high power. The entire

series is now available without grounding capacitors for safety-related applications.

Photovoltaic panels with increasing surface areas are being installed, and as a result ever more powerful inverters are required. To address this trend, SCHURTER is expanding the current ratings of its DC filters to 2300 A for higher power. For reasons of safety, filters are sometimes requested without grounding capacitors, which prevents any leakage current to ground. Thus, SCHURTER is also offering this entire series without Y capacitors.

Modern solar inverters with MPP (maximum power point) trackers generate interference in both directions: on the AC grid side and the DC panel side. On the AC side, it is usual to insert an AC filter such as the SCHURTER FMAC or FMBC, but until now few provisions have been made for the DC side. EMC standards EN 61000-6-3 and EN 55014-1, however, also limit the level of interference on non grid-connected conductors such as those going to a solar panel. A remedy can be provided by DC filters installed on the DC side of the solar inverter.

Large solar inverters are generally housed in cabinets that must have active cooling. The SCHURTER FMER series features high temperature resistance, which reduces the necessary cooling energy and makes a significant contribution to higher energy efficiency for the entire system.

FMER family filters have UL approvals for ambient temperatures of +55°C and +75°C as well as for rated voltages of 600 VDC and 1000 VDC. They are exceptionally well suited for rated currents from 25 A to 2300 A at an ambient of 55°C and for voltages up to 1200 VDC.

FMER SOL DC filters come standard with screw terminals up to 150 A, and with copper bars starting at 250 A. Other connection types (stranded wire or copper bar for current levels less than 250 A or bus bar terminals) are available on request. In addition, small modifications to the switching or the housing are also possible on request.

For optimal matching to the inverter, SCHURTER offers its own EMC measurement service that makes it possible to find the most cost-effective filter solution.

Technical features:

– Rated voltage 1200 VDC

– Rated current 25 A to 2300 A

– Connections: screw terminals 25 - 150 A; copper bars 250 - 2300 A

– cURus approval: 600 VDC 25 - 150 A, 1000 VDC 250 - 2300 A

How do I reduce Leakage levels using Cellergy super capacitors, to maximise battery life?

Andy_Brook — Thu, 07 Oct 2021 09:02:15 GMT

Current Revision posted to Documents by Andy_Brook on 10/7/2021 9:02:15 AM

How do I reduce Leakage levels using Cellergy Super Capacitors to maximise Battery life?

The very best way is to use a Cellergy Super Capacitor with nominal voltage which is higher than the battery nominal voltage (actually derating; for example use Super Capacitor rated as 4.2V for 3V application instead of using the 3.5V Super Capacitor).

A second way is to use a FET. A FET should be placed between the Super Capacitor and ground. The FET should close a circuit during Super Capacitor discharge and charge and open a circuit when the Super Capacitor is totally charged.FET switching is then implemented in the application where low leakage current is required. The Self discharge current of the Cellergy Super Capacitor (Super Capacitors leads at open circuit - FET is opened)) is lower than Leakage current.

Kemet Power Solutions (KPS) Single & Double Chip Stacked Multilayer Ceramic Capacitors

Andy_Brook — Thu, 07 Oct 2021 07:52:58 GMT

Current Revision posted to Documents by Andy_Brook on 10/7/2021 7:52:58 AM

KEMET’s KPS Series (KEMET Power Solutions) utilizes proprietary lead-frame technology to vertically stack one or two multilayer ceramic chip capacitors (MLCCs) into a single compact surface mount package. The attached lead-frame mechanically isolates the capacitor/s from the printed circuit board, therefore offering advanced mechanical and thermal stress performance. Isolation also addresses concerns for audible, microphonic noise that may occur when a bias voltage is applied.

A two chip stack offers up to double the capacitance in the same or smaller design footprint when compared to traditional surface mount MLCC devices.
Providing up to 10mm of board flex capability, KPS Series capacitors are environmentally friendly and in compliance with RoHS legislation. Available in X7R dielectric, these devices are capable of Pb-free reflow profiles and provide lower ESR, ESL and higher ripple current capability when compared to other dielectric solutions.

Tantalum users are moving to Super Capacitors

Andy_Brook — Thu, 07 Oct 2021 07:52:01 GMT

Current Revision posted to Documents by Andy_Brook on 10/7/2021 7:52:01 AM

There is a growing interest from Tantalum users to move to Cellergy’s Aqueous Super Capacitor Technologies

The market for Wireless Applications is growing at a phenomenal rate, such as GSM/GPRS, Bluetooth, RFiD, Zigbee and WiFi. With the nature of these products many are used within portable appliances and powered by Battery technology and therefore to support the Pulse requirements need to have Hi CV capacitor products with very Low ESR and low leakage to manage pulse requirements. Tantalum capacitor technology has been the incumbent source for many years but there are drawbacks.

One of the most common Tantalum Capacitance values is the 2.2uf whereas the lowest CV from Cellergy is 12mF. Leakage current can vary from 55uA to 130uA (Tantalum manufacturers vary) to just 3uA for 12mF Super Capacitors.

Tantalum manufacturers recommend only applying 50% of the nominal voltage in these applications, whereas Cellergy products work at the selected voltage.

Aqueous Super Capacitors respond well to Hi Discharge requirements for pulse applications, far more successfully than Tantalum Capacitors which adversely suffer from degradation when subject to constant Hi Discharge.

Super Capacitors are very stable in terms of their structure and electrical characteristics. Super Capacitor availability , price and lead times are also excellent.

Super Capacitors are now a serious consideration when compared to older Tantalum technologies. Cellergy technology offers a range from 1.2v to 14v in sizes starting at just 12mm square with Capacitances starting at 7mF rising to 700mF.
