HiFi RCA Passive Preamp Stereo Audio Preamplifier with Volume Control, A/B Audio Switch selector FV2

Seems to work great and adds more than I would have ever thought possible. I do recommend this item... I am hearing impaired and it is a really must have unit. Good sound quality, Easy to install and use, Sound Quality is great. FIts great in the small space that I have it in!

I needed something to switch between sending my tuner signal to my stereo for serious listening or to my fm transmitter to listen throughout the house. This worked perfectly and has no signal degradation I can hear at all. Just turn the volume control all the way up to not attenuate the signal at all. I opened it up because I have to and the build quality looks very nice and straightforward to me.

I bought this when upgrading to a DAC that didn't have a volume control, paired with an Emotiva A2L+ 2-channel amplifier, also without volume. This Tenealay is a passive amplifier so won't increase gain further, simply attenuate it, whch is fine since most sources (including mine) output sufficient voltage. The benefit to it being passive component is that it won't color the sound. The unit is solidly built, and the swich between sources works well. It's heavy, and looks good on my desk. My only concern is that turning the last 40 degrees or so, it's a bit grating, like a rake over cement. It worked just fine, but since this is the control I use most on my stereo rig, it has to be pleasant to use. Out of fairness, it was fine for small changes. It was only when making big volume changes on the upper end that I noticed it.

Perfect sound. Clean signal. Smooth rotating volume attenuator. Solid build. Everything I was looking for in a passively volume control.

It’s built solid..all metal, and had a relatively low price and, I hadn’t planned on using the second input “B” switch, I found that , let’s say you want silence for a phone call, just switch to the “ B” setting, and it works as an off switch, instead of turning the volume knob down, then back up after the phone call, and, its passive- no electrical cord

I bought this to control the volume coming out of a tape deck and in to powered speakers. It works exactly as I wanted - gives me precise volume control. Haven't used the A/B feature, or noticed and kind of background noise/sound distortion so far, but will update my review if I do.

Simple effective small footprint attenuator, perfect for linking a Bluetooth receiver to a massive amplifier. Note, this *does not* contain a preamplifier. It is unpowered. Its purpose is to *reduce* the audio level from the input device if necessary, for example the line level from a powered BT rx, before input to a 1kW stereo power amplifier. Without this attenuator, the BT rx would claim the audio signal as soon as the phone is in range and send full absolutely unhinged line volume to the power amp. With this attenuator, the automatic audio transfer to the BT rx results in an adjustable, sane, neighbor-friendly, output volume. My neighbors give this product five stars, which is a significant upgrade from their frantic text messages at 3am that BFG Division is shaking their house apart. This product will *not* work as a preamplifier for record players. It is an adjustable attenuator, not an amplifier, and it is very nice, even if my neighbors no longer get to listen to whatever I'm listening to.

It works as described.

Initial impressions were that it is smaller than expected and better looking, the pictures do not quite do it justice. The volume control has weight to it and feels the same as the RK27 alps pots I have in other equipment. The knob and case are aluminium and the whole unit is heavy enough that it does not move when you turn the knob, nor is it pulled by long cables. On connecting it I noticed that it has decent gold plated RCA plugs. On listening (ifi DAC, Adam active monitor speakers) I do not notice that it is there, which is how a passive pre amplifier should be. The channel matching is pretty good and it introduces no noise. If, like myself, you have active monitors which need a volume control (mine do, but on the back of each speaker, which isn't convenient) I fully recommend. It arrived early and well packaged.

Très bien et pratique, bel qualité de fabrication. Silencieux, volume souple

⭐⭐⭐⭐⭐ Excellent passive switch for DJ and studio monitoring setups. This passive RCA preamp and A/B switch is a fantastic addition to a DJ or studio monitoring setup. It allows clean, instant switching between sources or speakers with no added noise, hiss, or signal coloration, which is exactly what you want when monitoring accurately. The passive volume control is smooth and precise, making it easy to match levels between sources without affecting sound quality. Switching is silent and reliable, with no pops or interference — perfect for quick A/B comparisons or routing audio between monitors and secondary speakers. Build quality feels solid and professional, and the fact that it requires no power is a big plus for a clean, minimal setup. It worked perfectly straight out of the box and integrates seamlessly into a desktop or studio environment. Overall, an excellent value piece of gear for DJs, producers, or anyone needing transparent audio switching and level control. Highly recommended.

Excelente produto. Divisor que mantém a qualidade do sinal.

Es handelt sich um einen Lautstärkeregler mit 2 Eingängen, die wechselseitig ausgewählt werden können und mit einem Ausgang verbunden sind. So können 2 Geräte mit fixem Ausgangssignal z.B. ein Cd-Player und ein DVD-Player direkt mit einem Aktivlautsprecher oder einer Endstufe verbunden werden. Das Gerät ist recht klein und sehr gut verarbeitet. Ich kann es sehr empfehlen.
