This document is an owner's manual for Jamo Landscape Speakers, specifically covering the JL-4 and JL-10SW models. The manual provides instructions for installation and connections for these outdoor audio devices.
Function Description:
The Jamo Landscape Speakers are designed for outdoor audio applications, providing sound in a designated listening area. The JL-4 appears to be a full-range landscape speaker, while the JL-10SW is a landscape subwoofer, designed to augment the bass response of an outdoor audio system. Both models are intended for ground installation, with the JL-4 having an adjustable head for directing sound, and the JL-10SW being a buried subwoofer. They offer flexible connectivity options, supporting both standard 8Ω impedance connections and 70-volt constant voltage systems, which are common in commercial and large-scale outdoor audio installations. The JL-10SW subwoofer also supports stereo 8Ω, mono 4Ω, and 70V/100V mono connections, indicating its versatility for different amplifier configurations and system designs.
Important Technical Specifications (Derived from diagrams and text):
-
Jamo JL-4 Landscape Speaker:
- Installation Depth: The ground stake for the JL-4 is designed to be driven into the ground, with a recommended depth of 2.5cm - 5cm for the top plate to be flush with the ground.
- Optional Installation (Cement, Dirt, or Gravel): For more permanent or secure installations, a hole approximately 18cm wide and 26cm deep can be dug, and the stake can be secured with cement, dirt, or gravel.
- Adjustability: The speaker head can be rotated up to 45 degrees to direct sound towards the desired listening area.
- Connectivity:
- 8Ω Connection: Uses a red wire for positive (+) and a black wire for negative (-). The input wires are connected to the speaker's internal wiring via wire nuts: red to red, green to green, white to white, and blue to blue.
- 70 Volt Connection: Uses a red wire for positive (+) and a black wire for negative (-). The input wires are connected to the speaker's internal wiring via wire nuts: green to green, white to white, red to red, and blue to blue. This suggests internal transformer taps for 70V operation.
- Multi-Speaker 70 Volt System: Multiple JL-4 speakers can be daisy-chained in a 70-volt system, connecting positive to positive and negative to negative across all speakers and the amplifier.
-
Jamo JL-10SW Landscape Subwoofer:
- Installation Depth: The subwoofer is designed for burial, requiring a hole approximately 36cm wide and 26cm deep, with the top of the subwoofer remaining above ground.
- Connectivity:
- 8Ω Stereo Connection: This configuration uses two channels (Left and Right) from the amplifier.
-
Left Channel: Positive (+) connects to the green wire, negative (-) connects to the white wire.
-
Right Channel: Positive (+) connects to the red wire, negative (-) connects to the black wire.
-
The input wires are connected to the subwoofer's internal wiring via wire nuts: green to green, white to white, red to red, and black to black.
- 4Ω Mono Connection: This configuration uses a single channel from the amplifier.
-
Positive (+) connects to both the green and red wires.
-
Negative (-) connects to both the white and black wires.
-
The input wires are connected to the subwoofer's internal wiring via wire nuts: green to green, red to red, white to white, and black to black.
- 70V/100V Mono Connection: This configuration uses a single channel from a 70V/100V amplifier.
-
Positive (+) connects to the red and black wires.
-
Negative (-) connects to the green and white wires.
-
The input wires are connected to the subwoofer's internal wiring via wire nuts: red to red, black to black, green to green, and white to white. This indicates the presence of a multi-tap transformer for 70V/100V operation.
Usage Features:
- Outdoor Durability: The design of both the JL-4 and JL-10SW, with their ground-stake and burial installation methods, suggests they are built to withstand outdoor elements.
- Targeted Sound Coverage: The JL-4's adjustable head allows users to precisely aim the sound towards a specific listening area, optimizing the audio experience for different outdoor layouts.
- Flexible System Design: The availability of both low-impedance (8Ω, 4Ω) and constant voltage (70V/100V) connection options provides installers with the flexibility to integrate these speakers into various audio systems, from simple backyard setups to complex commercial landscapes requiring long cable runs and multiple speakers.
- Dedicated Subwoofer: The JL-10SW provides dedicated bass reinforcement, crucial for achieving a full and impactful sound in open outdoor environments where bass frequencies can dissipate quickly.
- Discreet Integration: The burial design of the JL-10SW allows for a very discreet installation, minimizing visual impact while providing powerful low-frequency sound. The JL-4, while visible, has a landscape-friendly aesthetic.
Maintenance Features:
The manual does not explicitly detail maintenance features. However, based on the nature of outdoor speakers, general maintenance would likely involve:
- Regular Cleaning: Wiping down the visible parts of the speakers to remove dirt, debris, and environmental buildup.
- Inspection of Connections: Periodically checking wire connections for corrosion or damage, especially since they are exposed to outdoor conditions. The use of wire nuts, as depicted, suggests that connections are intended to be secure and protected from moisture, but regular inspection is still advisable.
- Checking for Obstructions: Ensuring that the speaker grilles and drivers are free from leaves, insects, or other obstructions that could affect sound quality or damage the components.
- Ground Stake Stability: For the JL-4, occasionally checking the stability of the ground stake to ensure the speaker remains upright and securely positioned. For the JL-10SW, ensuring the buried portion remains undisturbed.
