User questions & answers

Question:	I use a splitter for two headphones and the volume drops. Will this amp help
Answer:	Get the older fiio e7. Great headphone amp, great sound, and two headphone outputs with the power to power both
Question:	I have a bluetooth transmitter with 2 bluetooth headphones that I use with low volume. Can I plug my transmitter into this for more volume on headsets
Answer:	You could potentially plug this between the audio player and the bluetooth transmitter. However, this is a portable device with a built-in Lithium battery, so you keep it plugged into the charger.
Question:	What is included with Fiio A1 portable headphone amp
Answer:	Mine included 2 3.5mm cables, one short (approx 4") with 90 degree connectors and one longer (about 2.5') with straight pin connections, a micro usb charging cable (about 2'), 3 plastic frames that protect the top part (one flush and two with belt style clips), and the amp itself.
Question:	I have been using an older Auvio, cheap and plastic. Is this upgrade worth the much higher price

User questions & answers

Question:	I live in an old house, My switches only have 1wire, the hot. No ground and no neutral in my wall switch boxes. Will this work for me
Answer:	You could use this in conjunction with the Insteon 2475F FanLinc Insteon Dual-Band Ceiling Fan and Light Controller, to controll the light functions. Use your remote to control the fan functions. The switch is of course unnecessary however.
Question:	Can you program 2 remotes to work with one switch? I want one wall mounted and one hand held
Answer:	This item needs to work with an Insteon hub, there is a hub that works with HomeKit. But this is a combination I have not tried.
Question:	Does anyone know if this dimmer works on a three way switch
Answer:	The Smarthome page for the 2466DW says nothing about dual-band. Neither the quickstart guide nor the owners manual say anything about dual-band. The owners manual states, in more than one place, that you need to "make sure you have installed at least two Access Points (#2443) or other dual-band INSTEON products". I think it's pretty certain that this product is NOT dual-band.
Question:	I purchased the Lutron P-PKG1W-WH and my new LED bulbs are flickering when being dimmed. They are dimmable bulbs and I have tried 2 different brands
Answer:	Yes. I have the 2466DW installed in my kitchen in a 3-gang switch box in the center between two other standard Lutron toggle switches. I needed the Insteon as it was the only toggle style dimmer switch compatible with controlling the low-voltage(twicebright CL1220TL) mini-recessed lights that use dimmable LED bulbs above my sink. The switch is high quality and easy to program for the desired on level.
