There are a wide variety of sound systems available to auctioneers. Most current models are wireless, or provide for optional wireless operation. We have advocated auctioneers always using a microphone when bid-calling.

From our survey of the marketplace at this time, it appears most auctioneers utilize one of three companies for their sound system needs:

From each of these company websites, we took what appeared to be the “high end” or premium model of their offerings, and compared their material features below:

Company Anchor Audio Lectrosonics AmpliVox
Model Liberty Platinum
LIB-7500MU1

Approx Base Price $2,319 $1,618 $2,503
Approx Price w 2 Channel & Tripod $2,819 $2,407 $2,725+

It is fair to say that both the Anchor Audio and AmpliVox systems, generally, also have features such as CD players, MP3 connections, USB Ports, Remote Controls, etc. The Lectrosonics system does not have such features built-in, but does have a 1/4″ jack, Mini-jack and RCA jack for optional inputs, as do the other systems noted here.

The other major difference between these systems is that the Anchor Audio and AmpliVox systems utilize direct radiating electro-dynamic drivers mounted in an enclosure, similar to home stereo speakers, car stereo speakers, and the like. Lectrosonics utilizes a horn type loudspeaker system.

When comparing these systems, the Anchor Audio and AmpliVox systems are somewhat similar, in contrast to the Lectrosonics system. Here are the more material differences in these systems:

    • Narrower frequency response
    • Lighter in weight
    • Quicker battery charging time
    • Fixed, VHF frequency
    • Longer wireless range
    • Less expensive
    • Wider frequency response
    • Heavier in weight
    • Slower battery charging time
    • Variable, UHF frequency
    • Shorter wireless range
    • More expensive

Lastly, all three of these companies appear to be on solid financial ground. This is important as once a system is purchased, it is meaningful to have both support for questions and factory repair/upgrade services available.

Quality auctioneer sound systems are not inexpensive. For auctioneers selecting their first system, or upgrading an existing system, this guide is intended to help with that decision.
