Description

The JBL Control 1 Pro is tough and can withstand many weather conditions thanks to its ABS cabinet. The speaker's 5.25-inch woofer and 0.75-inch titanium dome tweeter work together to deliver clear, balanced music throughout the frequency spectrum. Its compact size and low weight make it convenient for installation in tight spaces, and its resistance to the elements makes it ideal for use in outdoor settings.

As an added bonus, the Control 1 Pro has a multi-tap transformer that allows it to operate on either a 70V or 100V line, making it quite versatile. The paintable and removable speaker grille allows it to be seamlessly integrated into any interior design scheme.

Bracket Assembly and Mounting Guide

1. Screw the metal rod/ball assembly (1) into the threaded insert (2) on the back of the cabinet (8) until it is seated against the bottom of the insert.
2. Next, tighten the “knurled” nut (3) with a small wrench until it is seated against the back of the cabinet. Tighten the nut until it has “locked” the rod/ball assembly (1) to the cabinet. Note: the nut may leave marks on the back of the cabinet where the attachment is made however, the flange of the nut will cover these marks.
3. Mount the wall bracket plate (4) onto a flat sturdy surface using the appropriate mounting hardware for the surface. A safety cable (5) (not included) may be attached to the wall bracket via its eyelet (6) at one of the two lower screw mounting points or to a secondary point off the mounting plate.
4. Next, slip the large molded nut (7) over the ball on the metal rod/ball assembly (1).
5. Holding the cabinet (8) with both hands, insert the ball on the metal rod/ball assembly (1) into the cup of the wall plate (4).
6. Orient the speaker into the desired position and hand tighten the molded nut (7). Once the orientation is finalized, use the metal bar (9) in one of the holes on the molded nut (7) to securely tighten.
7. Finally, clip the safety cable to the cabinet’s safety bar (10) on the back of the cabinet.

Rotating the Logo

The Control 1 Pro’s logo can be oriented for display at 90° increments. To rotate the logo, first gently pry the grille and gasket from the cabinet. Next, push-in the logo’s fastener (found on the underside of the grille) and rotate the logo to the desired position.

Setup Guide

To set up the JBL Control 1 Pro, 

Start by selecting the appropriate mounting location. 

1. Make sure it's a stable and flat surface. The speaker comes with a wall-mount bracket, but you can also put it on a shelf or a floor stand.
2. Use the 1/4-inch phone jack or the binding post terminals that included with the speaker to attach it to your audio device.
3. Just adjust the transformer tap to match your system's voltage needs, whether it's 70V or 100V line operation.
4. After you've connected, activate your audio source and set the volume to your liking.
5. Depending on your program and environment, you might have to tweak the EQ settings.

Troubleshooting

If there is no sound from your speakers:

• Make sure your power amplifier is on and the gain is set above its minimum setting.
• Make sure there is a signal to your amplifier from your mixer.
• Ensure all wires are connected and that none are cut or frayed.
• If more than one pair of speakers is being used, check the minimum impedance requirments of your amplifier (overloading your amplifier can result in damage to your amp).

If there is no sound from one of your speakers:

• Check the balance control on your mixer.
• Check the channel output gains of your amplifier.
• Ensure all wires are connected and that none are cut or frayed.

If there is no (or weak) bass output or a poor stereo image:

• Make sure the polarities (+ and -) of the speakers inputs are properly connected.

Customer Reviews

Customers have praised the JBL Control 1 Pro for its excellent sound quality and durability. Many reviewers have noted its ease of installation and versatility in various applications. However, some users have mentioned that it may require additional EQ adjustments to optimize sound in certain environments.

A common complaint is the limited low-frequency response, but this is generally expected from a speaker of this size and price range.
