The Polsen BCPM-A2 In-Ear Monitor Amplifier Belt Clipis a compact and lightweight personal in-ear monitor amplifier that puts volume-boosting monitor control for headphones right at your fingertips. Ideal for keyboardists or drummers who stay in one spot while performing, the BCPM-A2 will deliver the audio feed you need without excessive cabling or clutter.

Designed as the active version of the Polsen BCPM-1, the BCPM-A2 is powered by two AAA batteries (available separately). The active amplifier circuitry gives you the advantage of boosting the input signal when you need extra volume in your headphones. Plus, the mono/stereo switch lets you choose the monitoring mode that matches your input source. The convenient belt clip ensures the BCPM-A2 won't be in the way while you play.

The BCPM-A2 features a combo input jack that accepts either XLR or 1/4" connectors, and the locking XLR connector guards against accidental disconnects on stage or in the studio. This road-worthy personal monitor amplifier is constructed with a durable metal chassis that can take the bumps and impacts of travel and stage performance.

The BCPM-A2 is an active device and runs on two AAA batteries. This gives the advantage of boosting the incoming signal with the active amplifier. If you need a little more level than the source is giving you, just turn up the volume.

The internal mono/stereo switch lets you select the mode that meets your needs. Select stereo when you connect to a headphone output or other stereo source. Select mono when you connect to a single-channel source such as a mono aux send from a mixer.

The volume knob / power switch is positioned at the end of the BCPM-A2 where it's easy to reach, even without looking. If you're sitting behind a keyboard or drum kit, changing the monitoring volume in your headphones is trickier than it sounds. If you can't walk over to the headphone amp or give the "more volume" sign to the sound engineer, the BCPM-A2 is for you. It puts a volume knob right at your belt, so you can dial in the perfect monitor level any time you need it.

Because monitoring is so critical to your performance, the XLR jack features a locking mechanism to prevent the connector from accidentally disconnecting—like if there's a little tug, or even if someone trips over your cable. When you're done, just press the locking tab to disconnect. Not using an XLR cable? No problem. The BCPM-A2's combo jack accepts 1/4" connectors, too.

Use your favorite studio or monitoring headphones, earbuds, or in-ear monitors. The standard stereo 1/8" (3.5mm) headphone jack accepts them all.

Thanks to the BCPM-A2's compact and lightweight design, you'll forget it's there until you need to adjust your volume. The monitor is made with a sturdy metal chassis that can take the bumps of travel and live stage performance.

Q: 4. If I get the correct cables could I send the signal from a crosley turntable to this, then to a receiver? The ol' yamaha is running down at -18db to be able to hear the records at a decent volume from the passive speakers it's driving... I need it amped up a bit before it gets there methinks.

A: I can't answer from knowledge of the specific turntable, but every phono I've ever known for the past 40 years requires a phono preamp for two reasons. 1) The signal level is way, way too low for directly connecting to a headphone amp or any line-level device. 2) Most importantly phonographs are all recorded with a very treble-skewed EQ according to the standard RIAI curve, a phono preamp is designed to nullify that curve by being exactly opposite towards a heavy bass response. In short, there is no substitute for a phono preamp. Make sure it is labeled and defined as phono preamp.
