Hosting Open Mic Night with the Bose L1 Pro 32…

Introduction

What to do? What to do with yourself in retirement that continues personal development? What do I like to do? I love the road and photography… Seeing live music is always fun too, but it’s even more fun to make music. Nevertheless, I’m not ready, nor interested in solo gigging at this time nor playing in a band… what is realistic for me is 15 minutes behind the open mic… I’ve missed the open mic as much as anything during the pandemic “lockdowns.”

Now consider this… What could be more fun than playing at an open mic night? Not only playing open mic night, but also hosting it! You get to play, organize the event, and operate the sound tech, and I’ve always loved tech. For example, I had a ball building a proper pedal board.

In my experience, the best existing open mic night in the Cedar Falls/Waterloo area is hosted by Rick Vanderwall and Bill Guernsey at the excellent coffee shop, Cup of Joe on Main Street. Yet it only happened (pre-pandemic) once per month on the third Friday.

It occurred to me a couple of months ago, as the pandemic began to wane somewhat, and I finished out my two Pfizer vaccinations, that it might be possible to add another open mic night at Cup of Joe on the first Friday of the month. I believed the interest would be there for an additional open mic session. This is especially true when you consider the sizable increase in guitar sales during the “lockdown.” My guess is there is now a more-than-modest increase in the number of live-performance aspirants with new guitars and open mic night is the place to start!

So… I asked Dawn, the proprietor of the coffee shop, if she would be interested in providing the space for an additional open mic night. Along with the request, I promised her that I would provide a “world-class” PA system to support the event… and, to my great, good fortune she said YES! Her only request was that I apply energy to make it a success by marketing the event in the community… fair enough!

A World-Class PA for Open Mic Night

I should note that before I embarked on this project, I enlisted my longtime-Iowa-best-friend and guitar playing partner in crime, Grant Tracey, as a cohost for open mic night with me. Running one of those events is really at least a two person operation. Without reservation he agreed to participate. Like me, he saw this as a routine way of getting to play publicly in an easily manageable way.

With Grant on the team, the next step was to acquire a sound system. Cup of Joe does not own a sound system, so a portable one is required to schlep in on the night of the event. A functional small venue sound system would offer multiple channels permitting a few microphones and two to three instruments, which are almost always guitars. Gigging performers at Cup of Joe often use multiple amplifiers; however, a multi-channel portable PA (short for public address system) is also commonly used. In fact, Rick Vanderwall, who hosts the third Friday open mic night has used a Bose portable PA system successfully for several years.

To the right, you can see Rick’s Cup of Joe open mic set up, with his early model, Bose portable line array in the background. Note in this image that he has three microphones and two instruments “plugged-in.” The Bose system is referred to as a “line array” because it uses a narrow vertical tower containing multiple two inch speakers alternatively angled left and right. In addition to the tower, which handles the mid and high ranges, there is a sub woofer to provide coverage for the lower sound frequencies. Sitting on a chair behind Rick you can just see a section of a mixer used to add extra channels to the PA and to manage tonal balances. I’m not sure about Rick’s, but some mixers, like Bose’s T4s also provide effects such as delay and reverb.

As I said earlier, I promised Dawn (of Cup of Joe) that Grant and I would deliver a quality sound system for our open mic nights. I did not want to beg or borrow a system, nor did I want to chase anyone around for funds. This project was initially my idea… I wanted to make it happen quickly and without complication, so I made the personal commitment to invest in a good PA. In the event that I ever do a solo gig, I would also be set up with a personal PA. These systems can be pricey, but I saw it as an investment in my primary retirement avocation. My retirement counselor at TIAA stated bluntly that if you want to do something that’s important for yourself, then do it now if it’s within reason and resources… don’t wait! So there it is… I went shopping for a PA.

I did some initial shopping at the local guitar shop and googled around on the internet, but I must admit I was predisposed towards Bose primarily because Rick Vanderwall’s system worked so well and reliably during the many open mics I played at Cup of Joe. Further, I’ve owned several Bose products, including floor standing speakers, bluetooth speakers, Wave radios and earphones. They were all solid products. In the end, if Bose was good enough for Rick, it was good enough for me!

Selecting a Bose PA for Purchase

It so happened that Bose just introduced a whole new line of vertical array portable PA’s in late 2020, so I had available to me the latest Bose technology to select from. Referred to as the L1 Pro Systems, they came in with three different models. The diminutive Pro 8, the middle size Pro 16 and the full sized Pro 32. The numeral refers to the number of speakers in the vertical array.

I must admit that I was a bit astonished when I first saw Rick Vanderwall’s Bose with the narrow vertical tower. The vertical array of smallish speakers accompanied with a sub woofer is relatively new technology, but it’s been widely accepted (and copied) since its introduction some years ago. Following is a Bose PA introduction from Youtube:

I spent a good deal of time studying reviews of the various Bose L1 Pros. Many of the reviews were simply regurgitations of Bose marketing literature; however, out in YouTube world were several independent reviews which helped clarify my final decision as to which model to purchase.

First a word on the space in which the PA must perform for open mic night. As you can see in the image of Cup of Joe, it is a long, relatively narrow space. The performers are located way down at the far end of the facility, so a PA system would have to possess the power to project along the entire length and width of the space. The music should project evenly so that sitting and standing people get roughly the same sound level, as well as from front to back of the room. Fortunately, Bose claims a properly spec’d and set-up L1 system meets those requirements.

In sum, my conclusion was the Pro 8 was underpowered for the venue in which Cup of Joe is located. The Pro 16 appeared to be a logical choice as it had the power to cover the space adequately, was reasonably priced and did not appear to be particularly cumbersome to move around. As you can see on the right, the Pro 16 comes in three pieces: the subwoofer, the longer array of sixteen two inch speakers and a 8 inch blank spacer that resides between the woofer and the speaker array. The purpose of the spacer is to raise the height of the sixteen two inch speakers to get a proper sound distribution. Unfortunately, the decision by Bose designers to use a “plastic” spacer has raised some criticism. Some reviewers claimed the spacer was insubstantially engineered resulting in wobbling of the tower. Other reviewers complained of a high pitched hiss emanating from the speakers. As I understand it, PA’s do come with a built in “noise floor” that varies by speaker design and system wattage; however, a high-pitched hiss is not what I wanted to contend with… period. I contacted Bose technical staff, but they were either evasive or oblivious to the critiques of the Pro 16. No help there…

Though it was more money than I initially wanted to spend, I decided to acquire the L1 Pro 32 because of the issues raised about the Pro 16. Bose offers either a very large Sub 2 or a smaller, (but big enough) Sub 1 woofer to pair with a two part vertical, floor standing tower. I chose the smaller Sub 1 because of its more manageable size and the low frequency sound profile was more in tune with live music, rather than DJ bass thumping that the Sub 2 is best designed for. Because both sections of the vertical array are substantial metal columns that lock into each other and because the column sinks several inches into the floor power stand, there is very little, if any, wobble.

The power stand offers a chunky, substantial, and stable base from which the vertical array arises. The stand connects to and powers the subwoofer with a proprietary cable, which is nice as only one 120 volt AC receptacle is required to power the entire rig. The stand also contains jack access to three channels. Two are 1/4″/XLR combo jacks, and the other is a 1/4″ jack with various other auxiliary possibilities, including bluetooth access. Lots of flexibility with channel tonal controls are available. The tonal controls are also remotely adjustable through an iPhone/Android app, which is super convenient. Finally, Bose has a baked-in library of tone profiles for various instruments and brands that can be deployed to fine tune the mix.

Here’s a Bose summary review of the L1 Pro 32:

Because the L1 Pro 32 power stand offers only 3 channels, I decided to acquire the Bose Tonematch T4s mixer to provide an additional 4 channels. The mixer attaches to the power stand with a ruggedized LAN cable, which transmits digital instruction to the L1 and receives power from the L1, thus keeping power needs simple. The T4s offers deep functionality in terms of sculpting sound profiles and will take me some time to master to its best advantage.

Experience to date with the L1 Pro 32

The Bose system arrived a day later than expected because of a freak snow storm that prevented UPS from getting to my home, so I was delighted when it finally arrived. I set up the L1 tower first, which went together easily and quickly. The connection to the Sub 1 also was rapidly accomplished. Sadly, I could not use the T4s because Bose recommended a firmware update and I had to order a cable from Amazon to connect my computer to the mixer.

• 

Without the T4s attached, I still had three channels and was able to test my Collings I 35 electric, my Taylor 812ce, my National Resolectric and a Shure SM 58 microphone all in my living room. In fact, via Bose software, I saved individual tonal setting in the system’s memory for each guitar. The system played clean as country water and interacted nicely with my pedalboard. The combination of the racetrack subwoofer and the 32 neodymium 2 inch drivers offered a consistent ear pleasing sound.

According to Bose literature, the speaker tower offers a floor to 7 foot high vertical sound spread outwards that also arrays itself 180 degrees, side to side. My experience was that you could sit anywhere in the living room of my house as long as you were not behind the tower and hear the music perfectly well. I made this test by bluetoothing my iPhone to the system and then playing the Beatles’ Revolver. When I disassembled the system and moved it up to my garage, the sound produced by the L1 could be heard across my yard quite easily when either Grant or I played guitar and sang.

Initial Disappointment and Concerns with the PA/Tonematch Combination

I will cut to the chase. After I updated the firmware on the T4s Tonematch mixer, I had intermittant success connecting it to the L1 Pro 32. In short, the instruments or mics channeled into the T4s received the signal as evidenced by a green flashing light, but failed to make it to the L1. It actually worked for a while in my living room, but when I disassembled the L1 and moved it to the garage, the T4s was a total fail! No matter what I tried, I could not get it to work.

The fail was on a Saturday, and on Monday Bose frontline technical help in the Philippines had no suggestions to remediate my problem of connectivity, but agreed to replace the entire system including the L1 and the T4s. The new L1 came the next day, but the T4s took almost two weeks to arrive. Even then, after replacement I had some initial difficulty making the connection between the two devices. I concluded that the weak link is the LAN cable and unless it is solidly connected, signal failure will occur. When queried about this shortcoming the Bose people were evasive. This time around though I was able to get the device to work in my living room, and after disassembly and reassembly up in my garage. So we’re good to go, but I do have some remaining qualms about connectivity issues between the two devices.

To be prudent, I plan to run another garage set-up to calm my nerves and make sure the system is functional.

We are Good to Go!
