A powerful personal PA for acoustic instruments.

L.R. Baggs is well-known as a manufacturer of pickups and preamps for acoustic instruments, and now the company is completing the signal chain by introducing a personal PA system, the Synapse, which combines a powered speaker with a two-channel mixer, digital reverb, and 500 watts of class-D power. We recently had a chance to check out a Synapse in the Peghead Nation video studio.

About as big as a medium-size guitar amp and weighing a manageable 38 pounds, the Synapse is designed to suit the needs of acoustic performers in a variety of venues, from small indoor spaces to larger halls and outdoor settings. The unit is designed around a complex horn arrangement placed in front of a compression woofer and tweeter, giving it 180 degrees of full-frequency sound dispersion. This means that a single Synapse could easily fill a large room or small hall. A speaker stand mount allows you to raise the unit off the floor, further helping distribute the sound evenly. The Synapse’s mixer includes two identical channels with combined XLR/¼-inch inputs, three-band EQ, and controls for gain and reverb. Small push-buttons are used to activate phase-reversal, mute, pad, and 48 volts of phantom power. The unit’s digital reverb was specially designed by L.R. Baggs’ engineers, who included a clever push-button for selecting long, medium, or short reverb times. The Synapse’s controls are completed by a master volume, an auxiliary channel with ¼-inch and mini-jack inputs and volume control, and XLR inputs, labeled “Mix In” and “Mix Out.” These XLR connections can either be used to daisy-chain multiple Synapses, send a signal to a larger PA, or connect a larger mixing board.

We checked the Synapse out in the Peghead Nation video studio using a Lowden O-10 guitar with an L.R. Baggs Anthem SL pickup system, as well as a Mario DeSio baritone with an L.R. Baggs M80 pickup. We ran both instruments through an L.R. Baggs Session DI and used an XLR cable to connect the Session DI to the Synapse. In addition, I used the unit at a solo guitar gig in a 100-seat auditorium. In both settings, the Synapse impressed with its full and natural sound reproduction, and the low-tuned baritone guitar posed no challenge to the unit’s ability to reproduce low-end frequencies. In the auditorium, the Synapse didn’t sound like a typical single-source speaker, but filled the room with a consistent volume level and tone no matter where the listener was seated.

Musicians looking for an amplification solution somewhere between an acoustic amp and a full PA should definitely check out the Synapse. With its great sound, intuitive operation, and ease of transportation, the Baggs Synapse will surely become a favorite of acoustic performers.

Hi Steve,

Thanks for your note. The audio you hear in the video is a combination of DI signal and an Audio Technica AT2020 in the room, which is there to pick up my speaking voice, but which of course also captures the speaker.

If this compression driver combined with horn loaded technology is so effective why is it not being used by the well established serious PA companies too ? The guitar in the review sounds very nice indeed but the review gives no indication what source we are hearing on the video soundtrack when Teja is playing? It does not sound like a mic on the Synapse, and sounds suspiciously like DI signal to me !

Every thing LR Baggs make is great. I have two pick ups,brilliant.But this retails in England for over two thousand pounds.It is astronomical priced for only two channels. I dont know how much you get for a gig in America but it would take a while over here to make it pay.There are many very good systems on the market for half the price,but I would still love one of these just the same. Great game

The comment about vocals is a valid one. My response may be worth what you paid for it, but here we go anyways: As a guitarist myself, my main gig is working in duo with my wife—who by all accounts/resume is a stellar vocalist. We had a chance to run her voice through early versions of this speaker system during development, in a variety of styles (classical/pop/jazz) and the results were fantastic. Again, for what my opinion is worth.

How can this be a review without vocals? I doubt if any body would just use this for a guitar amp.

The mandolin master plays a great version of the Jerome Kern classic with his trio, live at the Marshall Mandolin Summit.
