FAQ | Frequently Asked Questions

Below are some of your most common questions about our products and services. If you have an unanswered query, don’t hesitate to contact us.

Yes, through the stereo pre out/line out. This will let you control the volume and source with the Billie controls. Sound will be processed by the tube preamp and DAC, however the amplification will be handled by your active speakers.

Our general recommended speakers  specs are: impedance 4Ω to 8Ω, sensitivity: 85dB or higher. Can other speakers sound good too? of course, these are just a very general guideline.

Speakers are a matter of personal preference, and, truth be told, have a greater influence on your system’s sound than amplifiers. Do you want a slammy delivery or are you after a more mellow, enveloping sound? Speaker sounds vary greatly. Don’t hesitate to contact us for recommendations.

You can connect Billie’s PRE | LINE OUT to your sub’s LINE IN RCA connection . If your sub has crossover control,  adjust the crossover cut-off frequency to your speaker’s specs. The Billie output should be used in the default PRE mode, which increases and lowers the sub’s volume with Billie’s.

REL’s are intended to connect to the exact same terminals as your speakers, so you could certainly connect the high level cable to the set of speaker terminals. This allows the REL to receive the exact same full signal that your speakers are receiving.
However, since this amplifier is Class D it is very important to NOT connect the BLACK wire on the high level cable to the negative speaker terminal. Instead, you would leave this disconnected or, connect it to the vinyl grounding pin. In some cases, leaving the BLACK wire disconnected can cause the REL to hum because it is still searching for a ground reference. If this happens, you can solve this problem by running an RCA from the Billie PRE OUT to the REL’s .1/LFE input.

Tube lifespan is variable. Under normal wear, the tubes should last you between 10,000 – 15,000 hours. If you listen to your amp for 6 hours every day (without skipping a day), the tubes will last you between 4 – 6 years.

Tubes are fragile. Avoid handling them when hot. If you put too much force on the pins, you can break the vacuum seal and cause your tubes to burn (the silver caps turn white).

Normally, tubes will give you ample warning before dying: you will notice that one channel plays louder, slight distortion, or some sparking inside the tube when you turn on the amp.This is not dangerous but their end is near.

Changing tubes is only slightly more challenging than changing a lightbulb. 
The tubes on the Billie are easily accessed from the top, there’s no disassembly required. Just line up the tube pins to the socket and with a slight rocking motion while pinching the top dome, push them in.

No. The Billie uses preamp tubes. Only power amp tubes need periodic biasing.

Yes, they do -think 25w light bulb. Not enough to cause serious burn, but tubes are not meant to be handled when hot. Keep them out of reach of ‘little hands’.

The tubes used in the Billie (ECC99 or 12BH7) are very common and easy to find. Aside from our online store, you can find them locally at hi-fi and music stores.

We recommend getting a ‘gain-matched pair’ (we match our pairs to 0.1 dB). If you don’t get gain-matched pairs, your left and right channels will play at different volume.

The JJ ECC99 Gold Pin is based on the same construction as the classic ECC99. The internal components go through additional selection and processing during assembly. These tubes do test more consistently and have a lush and open character with an extended frequency response. You can install these gold pin tubes on any of our amps.

To use Billie’s bluetooth input:
-turn on your amp.
-Press and hold the (small) source knob for 5 seconds. The source will change to input#3 / Bluetooth and will put itself in pairing mode.
-Go to your phone’s Bluetooth preferences and look for “BillieAmp2”. Connect to it.
-Once you are connected and streaming, the blue source light on Billie will turn amber.
-Next time you’d like to connect your phone, just set the Billie source to input 3 and choose “BillieAmp2″ in your phone’s bluetooth devices.

-When you change sources, your device will automatically disconnect from Billie.
-When you press ‘mute’ on the Billie (by tapping the source knob), it also pauses the music on your phone.

-If you have powered Billie down, using the backpanel switch, you may need to “forget device” and repeat the pairing process

If you’ve previously paired to the amp, on your device Bluetooth preferences, click “forget this device”. Then press and hold the amp’s source knob until the Bluetooth light turns blue. On your device, find “Billie Amp” and pair with the amp. Every time you turn off the amp using the power switch, you need to forget and pair; you don’t have to pair again if you turned off with the volume knob.

No. Billie cannot cast Bluetooth, it can only receive Bluetooth.

If you’re having issues with the range of the Bluetooth, be aware that Bluetooth, like WiFi is sensitive to interferences. These interferences can be caused by nearby devices, like Smart TVs and routers, or materials, like masonry or metal.

Try relocating the amp or powering off the interfering device to isolate and identify the issue.

If your movie’s audio is buggy, it’s most likely that you’re sending a 5.1 signal. Billie’s DAC is optimized for  stereo playback and is unable to decode 5.1 or 7.1 signals. Most devices have a preference setting to send only 2 channel audio output. Check your TV’s or DVD’s manual.
