ICON AUDIO PASSIVE PRE AMP. Passive line preamplifier
If you are looking for a solution like this, the Icon Passive could be the ideal option.
Our passive preamplifier is perfect for use with most power amplifiers. Many audio sources, such as CD/DVD players, already generate enough voltage to reach an adequate volume, so additional amplification is unnecessary. Essentially, it is just about adjusting the volume level without adding extra components. By eliminating a preamplification stage, the sound remains pure and faithful, free from interference or unnecessary alterations.
Its main advantage is that it does not introduce distortion or noise, ensuring sound reproduction without artificial modifications. Additionally, it comes at a highly competitive price. It is built with robust materials and features gold-plated PTFE RCA terminals for excellent connectivity.
This is an affordable alternative to control your power amplifier without altering the audio signal.
The Passive model is highly versatile, as it can also be used as a selector box with the volume set to maximum or as a monitoring system for recording equipment. Moreover, it offers additional inputs, making it a valuable accessory for any high-fidelity setup.
In general, this device is compatible with any power stage or mono blocks with a minimum sensitivity of 1V or higher. These include amplifiers such as the QUAD 303 and all Leak valve models.
On the other hand, the Passive R offers the same specifications but with the added advantage of a remote control for volume adjustment. This allows users to precisely modify the audio level from their seat, compensating for possible variations between tracks or recordings.
This model incorporates a high-quality ALPS Blue potentiometer, the same one used in our other amplifiers with remote control. It is powered by a low-voltage power adapter included in the package.
