The Phoenix Gold Tantrum Series TLD66 line driver will enhance audio signal output from any factory or aftermarket head unit receiver. It will accept a signal from 1-5 volts and increase it up to over 8 volts. The result will be much better sound quality, unwanted distortion reduction, and a far improved dynamic range. Take advantage of the unit's 6 channel inputs and outputs, and prepare your audio system for a high quality 8 volt signal output for your front, rear and subwoofers!

The higher the preamp output voltage, the better signal to your amp and the louder your system will be able to go. It will also help offset the loss of voltage when driving multiple amplifiers from the same pre-amp output.

The higher signal level will also assist in eliminating unwanted noise from the vehicle into the audio system. For example, engine noise or whine that gets carried through the audio system will drop significantly or completely when the TLD66 is installed.

Don't be fooled by the low price. We bought a large quantity from Phoenix Gold and we got a special price so we're passing the savings to you. It's one of the best line drivers on the market. Phoenix Gold is one of the best companies in car audio and we've seen this line driver in both sound quality and SPL (loud) competitions. It's the best we carry and the lowest price... an awesome combination.

Line Driver Specifications

Max Output Level
The maximum level (in volts) of signal output. A higher level will increase the clarity and boost your signal.
8 volts
Speaker Level Inputs
Speaker level inputs are commonly referred to as high-level inputs and vice versa. This input type allows you to get your audio signal directly from the speaker wire in your vehicle, instead of using RCA cables. The advantage of this is factory integration, as most stock radios do not have RCA outputs to run amplifiers.
Total Number of Inputs
This is the total number of input connections that go into the unit.
Total Number of Outputs
This is the total number of output connections that the unit will produce.
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
15 - 20,000 Hz
THD (Total Harmonic Distortion)
The amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 0.10% is inaudible.
Signal-to-Noise Ratio
This spec compares the strength of the signal to the level of background noise. A higher value indicates less background noise.
110 dB
The width of the item from left to right (side-to-side) measured in inches.
The height of the item, measured from top to bottom, in inches.
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.

March 13, 2009

This is one of the best things i have bought for my system. It will make your power so clean the signal it puts out is so clean that your system just sounds so much better I have two of these and would not have it any other way. You can not buy anything even close at this price much less do a better job.

Purchased to try to correct a spl distortion issue, that I thought was the head unit, line driver works good, but does produce a very slight ringing in my tweeters when receiving no input. Otherwise, it works flawlessly, and each of the six channels is individually adjustable
