Radio Noise Issues

There is the possibility of getting a whine from the car's ignition when the audio device is powered from car electrical system. This ignition noise can be solved with noise supressor on the power line or a ground loop isolator noise supressor. This noise has nothing to do with the cables used to connect to the auxiliary of the radio.

I offer both types of noise supressors.

For noise supression on the electrical power line, I offer the Pyramid NS-2 as shown below for $7.00 plus shipping. Click here to for details on how to purchase this items.


For noise supression on the audio line, I offer the Pyramid NS-20 as shown below for $10.00 plus shipping. Note that this product has RCA plugs to connect to the audio line. Click here to for details on how to purchase this items.


There is also the possibility of low volume compared to the volume of the CD or radio tuner. This is due to the higher power output of the CD changer and tuner versus most personal audio devices and XM radios. To solve this issue, I offer the Turbo1 preamplifier. The Turbo 1 increases the preamp level being delivered to the amplifiers (or in this case the head unit). Increasing pre-amp level signal helps to better balance your system.

S/N ratio of 96 dB for high quality sound
Average draw is less than 15 milliamps
The Turbo 1 is adjustable from 0.1 to a 15dB increaseThe unit is adjustable.

The Turbo1 as shown below is $32.00 plus shipping. Note that this product has RCA plugs to connect to the audio line. Click here to for details on how to purchase this items.



SPECIAL CABLE

I offer a special cable called an RCA-F-60. This 60" long cable has a pair of RCA male plugs at one end and a female 1/8" stereo panel mount plug at the other end. This cable allows you to connect to the input of the PIE LD1 amplifier and then run the wire to the center console or to the plate under the radio. You would still need another cable I offer to connect from the auxiliary input to the output of the LD1.

An example of the wiring would be:
iPod ==> RCA-F-60 ==> NS20 ==> Turbo1 ==> AV-RCA-60 ==> Radio Aux.
