FAQ

Answer:
The 63SA-4 and 63SA-7 include a overload protection circuit. If you exceed the power limits of the circuit, it will reduce the volume substantially. You need to turn down the volume to allow the circuit to reset and play at a lower level in future.
 
The power level at which the protection activates can be adjusted by changing the value of the circuit protector which is accessible by removing the mid/high module.  Different rated protectors can be purchased from James.  However, bear in mind that increasing the power handling also reduces the protection afforded by the circuit in the first place. So if your speaker is unaccessible behind the ceiling material, you need to maintain a good level of protection.  You should discuss these options before changing the protection level.
Answer:

There are many ways to paint James small holes aluminum perforated grilles. Here are a couple of painter’s trick that work well.
Spray rattle can method:
- The surface of the perforated grille must be thoroughly cleaned with a non-residue solvent.
- Raw aluminum perforated grilles must be primed before painting. 
- Start with inside (rear) - this painting process will cover most of the perforated holes.
- Clogged perfs can be cleared with a shot of compressed air or air compressor.
- Let it dry sufficiently and turn the grille over.
- Working on the front side, the first coating must be a light spray (dusting), tilt the rattle can to about a 45 degree angle, let it dry for 15 minutes, light dust spray a second coat again until the whole surface is covered.
- A third and fourth spray coat may be required, “DO NOT OVER SPRAY”
- The grille must be completely dry before installing.
Water base paint:
- The surface of the perforated grille must be thoroughly cleaned with a non-residue solvent.
- Raw aluminum perforated grilles must be primed before painting.
- Add about 30% water (based on paint volume) to the water base paint to thin and mix well.
- Dab paint over inside (rear) of the perforated grille lightly using clean rag or foam material and let dry for an hour.
- Dab paint over front side of the perforated grille with rag or foam material.
- Must let it dry 20~30 minutes between steps.
- Once completed, let dry for a couple of hours prior to installation.

Answer:
If the QSC amp DIP switch settings are incorrect, you might have a low-cut filter turned on. The DIP switches are on the rear of the amp, and are under the DSP4 if the DSP4 has been installed. The default settings are: DIP-1 and DIP-10 are ON (to right) and DIP-2 through DIP-9 are OFF (to left).
Answer:

Unless instructed otherwise by James, the default settings are: DIP-1 and DIP-10 are ON (to right) and DIP-2 through DIP-9 are OFF (to left).

Answer:

The QSC CX Series 70V amps used by James are professional grade amps and have an input sensitivity of approximately 1.2V for full output. Consumer level products may not be able to drive the QSC amp to full level. Normally, each amplifier is supplied with a DSP4 processor programmed with additional gain, making the QSC amp compatible with consumer output levels. If your installation requires additional gain, consult James on how to reprogram the DSP4 for more gain.

Answer:

James supplies XLR-to-RCA adapters with each DSP4. If you did not receive the adapters, contact James to request adapters. If you need adapters immediately, local stores such as Radio Shack stock adapters.

Answer:

Our tests have proven on installations up to a 1000', signal loss is not detectable.

Answer:

Any 70V speaker can be added to a 70V line as long as there is enough power available in the amp. However, there will be no control over the relative sound level from each speaker. In the case of the 31ODS70 and 62ODS70, the 62ODS70 will be about 8dB louder than the 31ODS70 so this needs to be considered when the sats are placed on the site.

Answer:

Use the existing 1/2" tall trim rings and calculate the additional thickness you need to make up for the wall thickness. Purchase the SA-SP-0.125 1/8" thick spacer rings to make up this thickness and install with the trim ring. NOTE: you will also need longer screws. James stocks some lengths up to 2.5" - call to check stock.

Answer:

The length of the PowerPipe port is part of the integral tuning of each PowerPipe subwoofer. Generally, we can vary the length +/- 6 inches or so. As the port length is increased, the tuning is lowered which reduces sensitivity but lowers the low frequency and high frequency limits of the woofer. As the port length is reduced, the tuning is raised which increases sensitivity but raises the low frequency and high frequency limits of the woofer.  However, generally we can work to solve most installations that require longer runs - call us!
