Introduction: 

But when creating a live sound system, one easily becomes obsessed with the "glamour" hardware. You have spent several weeks searching for the right mixing console, the best active line arrays, and suitable vocal microphones. Yet, a good audio engineer knows for sure that the best PA system is always dependent on the weakest point in the chain.

In the audio equipment configurations, failures seldom occur owing to the failure of the mixing console. On the contrary, they usually occur due to the damage to a up to $ 13 cable, interference from an unshielded power supply, or the dropping of a costly condenser microphone into the floor thanks to an affordable microphone stand.

These are the audio accessories which you should consider when assembling a reliable live sound system:

1. High-Quality Cables and Strategic Signal Management :

Cables are the veins and arteries of your sound system. In a live environment, they are stepped on, rolled over by heavy cases, twisted, and exposed to liquid spills. Investing in tour-grade cabling pays dividends in reliability and sound fidelity. 

Premium Microphone Cables (XLR) :

Since microphones transmit sensitive and very low-voltage audio signals, they can be easily affected by any form of interference in the environment. Choose the XLR cables having: 

• Oxygen-Free Copper (OFC) Conductors: For highest conductivity and purity of signal. 

• High Braiding of the Shielding:  With 90% braiding protection of the signal from adjacent light rigging or wireless signals. 

• Durable Connectors: Neutrik or Amphenol connectors that endure thousands of insertions and withdrawals without loosening of the pins. 

Balanced and Unbalanced Line Cables: 

It is important to know the distinction between TS (Tip-Sleeve) and TRS (Tip-Ring-Sleeve) cables for proper noise reduction. Unbalanced TS cables will become affected by interference when used for runs longer than 15-20 feet. Balancing the signal in TRS cables will eliminate external noise during long runs. Always use balanced connections for main runs to amplifiers and powered speakers (TRX or TRS). 

Audio Snake / Stage Box: 

Instead of twenty microphone cables run individually from the stage to the mixer at front-of-house, all of these signals could be routed in one heavy-shielded umbilical cable - the audio snake. Either way, using this device will greatly cut down on clean-up time and trip hazards. 

2. Direct Injection (DI) Boxes: The Unsung Heroes: 

Should you be connecting an acoustic guitar, keyboard, or bass straight into your stage equipment, a Direct Injection (DI) box is absolutely necessary. Typically, musical instruments send out a high impedance, unbalanced signal. Attempting to take an unbalanced guitar cable and run it 50 feet along a stage into a mixing board will essentially turn that cable into a huge antenna for any buzz and radio frequencies in the area, along with losing your treble. 

How a DI Box Functions:  It immediately converts high impedance and unbalanced signals from musical instruments into a low impedance, balanced signal for an XLR connector. 

Additionally, nearly all DI boxes have a Ground Lift button. That small switch could very well save your entire concert from hums of 60Hz generated by ground loops. 

3. Road-Worthy Infrastructure: Stands and Power :

The proper setup needs a solid physical infrastructure. Neglecting stand design or power distribution leads to physical and electrical issues. 

High-Quality Microphone and Speaker Stands: 

Poor quality stands will slip down during the performance, dump their heavy speaker loads, or fall over when bumped by an exuberant performer. 

• For Microphones: Get stands with robust cast iron bottoms or durable wide-tripod locking stands using heavy steel tubing. Locking ergonomic clutches are a must-have. 

• For Speakers: Choose stands that have safety pins which pass through the vertical column of the stand. Do not depend only on friction clamps for holding a 50-lb. speaker over a head full of people. 

Power and Power Management: 

Most venues, particularly older clubs or bars or even outdoor stages, have very unreliable electrical power. Typical power strips provide some surge protection but do not filter out all the electrical "noise" produced by refrigerators, air conditioning systems, and dimming lighting equipment. 

A rack-mount power conditioner helps regulate voltage changes and blocks any radio frequency and electromagnetic interference. This ensures that you do not experience crashes in your digital mixers and avoids any hiss ruining your high-frequency compression drivers. 

The Definitive Live Audio Accessory List :

To ensure that you are prepared for your next event, check to see that your accessory kit includes the following indispensable accessories: 

• Accessory Type | Necessary Accessories | Function | 

• Testing Equipment | Cable tester, SPL meter | Fast troubleshooting and volume checks | 

• Cable Control | Velcro cable ties, heavy gaffer tape | Ensuring proper connection and avoiding stage tripping | 

• Adapter Devices | XLR to TRS, TRS to RCA, 3.5mm mini jacks | Converting unexpected guest devices or backup equipment | 

• Replacements | AA/9V batteries, guitar picks, microphone clips | Immediate replacement of depleted/broken on-stage devices | 

Conclusion :

Live sound perfection begins at the very beginning, starting from the bottom up. Even though expensive main speakers and quality microphones get all the attention, it is the simple accessories such as premium microphone cables, tough DI boxes, secure stands, and proper power supplies that keep everything functioning well. Taking the same amount of money and analysis into consideration when buying the accessories as for the components will ensure a professional and flawless live sound performance each and every time.
