Do you need more inputs, volume control and remote control?
If you need any of these the Icon Passive R could help. Icon Audio's passive preamplifier is ideal for use with most power amplifiers. Most CD/DVD, tuners etc already have enough voltage. Its beauty is that it has no distortion or noise, therefore does not colour the sound, and the price is very affordable.
Passive Line Pre-Amplifier
Why do you need a pre amplifier?
Aside from tone controls and balance which thankfully most high quality pre amps have dispensed with, the principal reasons are:
1, Voltage, gain where your 1 volt tuner output needs to drive a 1.5v power amp input.
2, Where the capacitance of very long connecting leads degrades the high frequency.
On the other hand your modern tuner, CD player, phono pre amp etc probably has enough output to drive your power amp(s) effectively, and you will probably be using relatively short (0.5 to 3m) leads. In which case you only need to control the volume, and switch the input. Nothing else!
Some years ago QUAD described the perfect amplifier as a piece of wire with gain. But as there is no such thing as a perfect amplifier, by default the Icon passive is considered perfect, as it has no flaws! This may sound conceited, but it is the basis of all their integrated amplifiers. There is no hum because it is perfectly screened.
There is no noise because there is no amplifier to make noise. Distortion is non existent. This is the only way to hear the true sound of your power amplifier, with nothing added.
The Passive is very versatile and can also be used purely as a selector box with the volume wide open.
Or by providing a monitoring circuit for your recording equipment as well as additional inputs. It is a very
useful addition to any hi fi system.
As a general guide it may be used with any power amp or mono blocks with 1v sensitivity or greater.
This includes the QUAD 303 and all of the Leak valve amplifiers.
