Audio Upgrade and Memory Backup

The Audio Upgrade consists of replacing key components in the audio signal path. The end result is an improved clarity to the audio which improves overall intelligibility (consonants like c's, k's and q's have improved definition). This also reduces listening fatigue. The Memory backup requires the installation of a 100,000 uf (0.1 Farad!) capacitor across the AA memory back-up batteries. This allows removal of the AA batteries for up to ten minutes without loss of installed memory information. Complete installation instructions are included.

For more information regarding Kiwa Audio Upgrades- please see Kiwa Audio Upgrades - A Brief History.

Wideband Filter Upgrade

The wideband filter upgrade replaces the wide filter with the Kiwa “Blue Dot” filter.  This filter has a -6 dB bandwidth of 6.8 kHz.  This bandwidth still allows good fidelity while improving selectivity or the ability to reject adjacent frequency interference. The stock wide filer typically measures 9 to 13 kHz depending on the production run.
