Product Information
Full details
The Adastra FC Series Compact Background Speakers are designed for discreet audio integration in environments requiring durable, weather-resistant sound. Ideal for gardens, outdoor shelters, health club spa areas, and marine applications, these speakers offer versatile operation with either 100V line or 8 Ohm settings. While they provide robust performance and UV protection, users should note that their compact size may limit bass response in very large open areas.

FAQs
What is the IP44 rating?
The IP44 rating signifies that the speaker is protected against solid objects larger than 1mm (like wires) and is protected against water splashes from any direction.
Can I use these speakers with a standard home stereo amplifier?
Yes, you can use them in 8 Ohm mode with a standard stereo amplifier, provided the amplifier can handle the load and has sufficient power. For 100V systems, you need a dedicated 100V amplifier.
How do I adjust the equalization switch?
The equalization switch is typically a small toggle or slide switch located on the back of the speaker. It's designed to be adjusted manually to boost higher frequencies for outdoor use.
What is the difference between 8 Ohm and 100V operation?
8 Ohm operation is standard for home audio and provides a direct connection. 100V operation uses a transformer and allows for multiple speakers to be connected in parallel over longer cable runs with consistent volume.
Are these speakers suitable for direct rain exposure?
While they have an IP44 rating for splash protection and UV resistance, they are not designed for continuous direct exposure to heavy rain. It is recommended to install them in a location offering some protection, such as under eaves or overhangs.
What is the maximum number of speakers I can connect in a 100V system?
The maximum number depends on the total wattage capacity of your 100V amplifier. You calculate this by summing the wattage tapping selected for each speaker and ensuring it does not exceed the amplifier's rated output.
Do these speakers come with mounting hardware?
Yes, the Adastra FC Series speakers include an M6 threaded mounting points and a wall mounting bracket for installation.
Troubleshooting
No sound from the speaker
Check all wiring connections for tightness and correct polarity. Ensure the amplifier is powered on and set to the correct input source. Verify the correct wattage tapping is selected on the 100V setting, or that the amplifier is stable at 8 Ohms. Test with a different speaker or cable to isolate the fault.
Distorted or muffled sound
Reduce the volume level. Check for physical obstructions in front of the speaker. Ensure the speaker is not overloaded by the amplifier (check wattage ratings). For 100V systems, ensure the selected tapping wattage is appropriate for the amplifier's capacity.
Low volume output
Increase the amplifier's volume. On 100V systems, try selecting a higher wattage tapping on the rotary switch. Ensure the speaker impedance (8 Ohm or 100V tapping) matches the amplifier's output configuration.
Speaker cutting in and out
Inspect speaker wire for damage or loose connections. Ensure the amplifier is not overheating or entering protection mode. On 100V systems, check for loose connections at other speakers in the chain, as this can affect overall performance.
Pros and Cons
Pros
- Durable, weatherproof design suitable for challenging environments.
- Flexible installation with 100V/8 Ohm options and included mounting bracket.
- Adjustable EQ for improved clarity in outdoor settings.
- Compact size allows for unobtrusive placement.
- UV protection extends product lifespan.
Cons
- Limited bass response due to compact driver size.
- Frequency response starts at 114Hz, may require a subwoofer for full-range audio.
- IP44 rating offers protection against splashes, not direct high-pressure water.
- Rotary selector switch requires manual adjustment.
Setup, Compatibility & Care
Setup:
- Determine Operation Mode: Decide whether to use 8 Ohm or 100V line operation. For 8 Ohm, connect the speaker directly to an amplifier's 8 Ohm output. For 100V, connect to a 100V amplifier output.
- Select Tapping (100V Mode): Use the rotary selector switch on the rear of the speaker to choose the desired wattage (20W, 10W, 5W, or 2.5W). Match this to your amplifier's capabilities and desired volume level.
- Connect Wiring: Use appropriate gauge speaker wire. Ensure correct polarity (+ to + and - to -) when connecting to the spring terminals.
- Mounting: Utilize the included wall mounting bracket or the M6 threaded mounting points for secure installation.
Compatibility:
- Amplifier: Compatible with amplifiers supporting 8 Ohm loads or 100V line outputs. Ensure the amplifier's total wattage and impedance ratings are suitable for the number of speakers used.
- Wiring: Standard speaker wire is required.
Care:
- Cleaning: Wipe the exterior with a soft, damp cloth. Avoid using abrasive cleaners or solvents.
- Maintenance: Periodically check wiring connections. Ensure the speaker grille is free from debris.
- Protection: While weatherproof, avoid prolonged direct exposure to heavy rain or high-pressure water jets. Ensure the equalization switch and rotary tapper are set correctly before enclosure.
