R100T2
High-quality attenuator for proper control of tweeter and midrange volume balance
This product cannot be used as a volume control for the entire speaker volume.
Please read the "Precautions for Use" below.
R80B: High input attenuator
R82B: High input attenuator with 2 sets of windings in series
R100T2: Transformer type attenuator
◎ R100T (former model) → R100T2 Major changes
The rotary switch has been changed. Reliability has been further improved by using special silver alloy contacts to maintain stable contact resistance.
Low-loss gold plating is used for the internal input/output terminals.
External dimensions are different, so please be careful when replacing.

Attention
This product adjusts the balance by attenuating the volume of the tweeter (high frequency range) and the screener (mid frequency range), and cannot be used as a volume control to adjust the volume of all speaker bands at once. Please use this product with the signal cut off in the bass range (*below 500Hz) by a network circuit such as capacitors and coils.
Do not use this product with full-range (full frequency range) signal input, as it may cause heat generation and fire.
