Jackery Explorer Power Station 500

Overview

These are the results of using a Jackery Explorer Power Station 500 to run L1 Pro (various) and L1 Model II with ToneMatch Mixer[1], two B1 bass modules, and Kemper Stage electric guitar processor.

Conclusion - Jackery Explorer Power Station 500 should provide power for moderate-to-high volume for at least five hours for an L1 Pro or L1 Legacy system with a ToneMatch Mixer[1].

  • You should get comparable results with an L1 Compact.
  • The power consumption is similar for all models. The volume (Sound Pressure Level SPL) determines how much power you consume. The louder you run the system, the faster you deplete the power. For example, you might get 7 hours of music at 80 dBC SPL and only 2 hours at 110 dBC SPL.
Update - L1 Pro Systems (Pro8, Pro16, Pro32 with Sub 1)
I have repeated the same tests using the L1 Pro systems. The power consumption is comparable to that shown for the L1 Model II with two B1s shown in the tables below.

Run Time Calculation Examples

518 watt hours x 85% (for inverter efficiency) = 440 watt hours.

Example: L1 Model II + 2 B1 + T4S at 100 dB

440 watt hours / 75 watts = 5.9 hours

Add draw from Kemper Profiler Stage at 12 watts

440 watt hours / (75 + 12) watts = 5.0 hours

If using a T8S instead of T4S add 5 watts to draw

440 watt hours / (75 + 12 + 5) watts = 4.8 hours

L1 Compact[2] (60 watts at 100 dB) + T4S

440 watt hours / (60 + 20) watts = 5.5 hours

Remarks

Occasionally I perform outdoors in settings where an S1 Pro system doesn't provide adequate coverage. I wanted a solution to power an L1 Compact and a ToneMatch Mixer[1].

Minimum Requirements
  • Pure Sine Wave[3] inverter
  • Minimum run time at moderate volume (85 dBC SPL) 5 hours

The smallest capacity unit I could find was the Jackery Explorer Power Station 500.

Here's my rationale that led me to test using the L1 Model II.

For most outdoor gigs:

The L1 Pro models share a common user interface and the L1 Mix app. This page has links to resources for all three models and the Bose products that integrate with them.

Quick Tips

L1 Pro Line Out

The XLR Line Output from any L1 Pro contains the sound from all inputs (1, 2, 3, Bluetooth, and ToneMatch Port). That includes

  • ToneMatch Presets
  • Tone Controls
  • Reverb
  • The signal from a ToneMatch mixer connected to the ToneMatch port including ToneMatch Presets, zEQ, Reverb, Effects.

The sound is NOT affected by the L1 Pro System EQ setting.

L1 Pro System EQ

The System EQ feature on the L1 Pro systems applies an EQ preset to the master output. This is similar to a graphic equalizer on traditional analogue mixers, but it uses four presets instead for quick access. read more — L1 Pro System EQ

L1 Pro32 Half Stack

Can I operate the L1 Pro32 with only the lower section of the line array?
Sometimes there is not sufficient height to use the full array
Yes
The L1 Pro32 can be used without the upper array. This configuration is useful when a venue ceiling cannot accommodate the height of the L1 Pro32
Source: Page 7 of the L1 Pro32 Owners Guide
  • For best results, ensure array is at ear level for listeners
  • Unlike the L1 Model II, the L1 Pro32 automatically adjusts the level of the bass output to maintain the appropriate spectral balance.
It’s a valid use case to use only the bottom array section. In fact, the EQ automatically adjusts to compensate.
Craig Small - Bose


Half Stack Not Recommended for Small Gigs

Running only the lower section of the Line Array is a workaround when there isn't enough ceiling clearance to use both sections. For small gigs, turn down the volume on the L1 Pro32, don't run without the top section of the array because

  • You'll need to elevate the system so the array is at ear level for the audience. Otherwise, the sound will be muffled
  • You will reduce your projection over distance. The sound will drop off more over distance.
  • You may need to turn up the volume louder than if you were using the full array. As a result, you increase the likelihood of feedback.

FAQ

Q
What are the mid-high array and lower mid-high array made from? Metal mesh front and is rear metal or plastic?
A
Arrays on all units feature an extruded aluminum sleeve. Perforated grille on the front, solid on the back. Source: Craig Small
Q
Are the column speaker arrays interchangeable between the different models? (L1 Pro8, L1 Pro16, L1 Pro32)
A
No. While the column arrays and extensions of the L1 Pro8 and L1 Pro16 will fit each other, no sound comes out.

Bose Music App / L1 Mix App

March 2023 - The L1 Mix App is replaced by the Bose Music App
Note: If you currently use the L1 Mix App, you may see a message that says to switch to the Bose Mix App. If you're not ready to do that (e.g., you're at a gig), tap the X to dismiss the message so you can continue with the L1 Mix App.
L1 Mix App is Moving to Bose Music

Firmware version 3.0.0 is required to use the new app.

For more details about the firmware update see: L1 Pro Firmware

Introduction to the Bose Music App

It's L1 Pro control in your pocket. With the Bose Music app, you can access intuitive, wireless control of your Bose L1 Pro portable PA system.


Tip

Run your finger up and down over the dials (as though they were sliders). Don't try to follow the curve.

ToneMatch Mixers

T4S This information is applicable to the T4S ToneMatch® mixer
T8S This information is applicable to the T8S ToneMatch® mixer

Engineered with a powerful DSP engine and intuitive user control, the T4S/T8S ToneMatch mixers offer studio-quality EQ, dynamics and effects. Sound great with integrated BoseToneMatch processing and zEQ, especially when connected to a Bose L1 or F1 system for full end-to-end tonal control.
