Speakers and amplifiers:
Q:"Is a speaker wire supplied? How much does it cost?"A: Speaker wire is provided when you buy BSP50 speakers. There is one 3 metre length per speaker. If you need longer wire Homebase and B&Q have inexpensive loudspeaker wire.
The JB7 was designed for 8 ohm loudspeakers - like our BSP50s - but JB7 owners have used the JB7 with hundreds of different loudspeakers without problems. The BSP50s are matched to the power and physical size of the JB7. If you are looking for higher quality loudspeakers then you need to think about spending more than £200.
Q:"Can I purchase my own speakers for the JB7?"
A:22cm (H) x 14.5cm (W) x 18cm (D)
Q:"What are the dimensions of the speakers?"
A: The JB7 uses an Analog Devices AD1981 Codec and two Monolithic Power MP7782 Power amplifiers. Refer to Monolothic Power for details.
Q:"What amp does the JB7 use?"
Yes - about half our customers use JB7 with an existing amplifier. You can either use the JB7 line-out or the headphone out. (Both use 3.5mm stereo jack connectors.) The advantage with using the headphone out is that JB7 detects the headphone is being used and turns off the internal power amplifier. Also the main control can be used to adjust the volume of the headphone out - the line out has a fixed level.The JB7 power amps are happy to run without any speakers connected.
Customers have connected the JB7 to amplifiers from a huge variety of manufacturers - Bose, Denon, Sonos, Linn, Arcam, Sony - you name it - without any difficulty.
Q: "Can I use my laptop to play website music etc. through the JB7 amp and speakers?"
Now you will need to go to the JB7 Menu and select Recording.You will need to connect one end of the cable into the laptop's “headphone” socket and the other end of the cable into the “Aux in” at the back of the JB7.
Connecting to Loudspeakers, a HiFi or a radio
If you want to feed the JB7 into a HiFi you will probably need a lead with a 3.5mm stereo jack on one end and twin phono (RCA) plugs on the other. You can plug the jack into the Headphone output or the Line Out but we recommend the headphone because it turns off the internal power amplifier, it allows you to adjust the level and it has a lower impedance so can give better quality. I measured a signal of 2.3V peak to peak on the headphone out.
