The HR-MP2 is a dual channel microphone preamplifier with line-level outputs. Each section provides identical rear-panel signal connections and front-panel controls.

Each preamplifier is equipped with a front-panel FILTER switch to enable or disable a 6 dB/octave low-cut filter with a -3 dB cutoff at 80 Hz. Two additional switches on each input select 24 V or 48 V phantom if the master PHANTOM power selector is ON. The INPUT PAD switch allows the operator to attenuate the input signal by 15 dB prior to the preamplifier input stage, increasing the maximum input level from +5 dBu (attenuator out) to greater than +20 dBu. A POLARITY switch provides signal polarity reversal if needed. The GAIN control provides continuous adjustment between 20 dB and 60 dB. An RDL Dual-LED VU meter is provided adjacent to each gain control. The meters are calibrated to indicate +4 dBu at the associated balanced output. A separate CLIP LED flashes if a signal peak is within 3 dB of clipping. The trigger threshold of the CLIP LED is 17 dB above a normal +4 dBu output.

The HR-MP2 offers exceptional input headroom, wide flat frequency response and extremely low noise with very high common-mode signal rejection. Total harmonic distortion and crosstalk are below the noise floor, allowing the HR-MP2 to be operated as a stereo preamplifier or as two separate mono preamplifiers.

Each preamplifier provides three balanced line-level output formats: XLR male, detachable terminal block and ¼” TRS. A separate summing amplifier provides a combined mono output on a line-level detachable terminal block. Balanced outputs may be wired unbalanced. The rear panel also provides a detachable terminal block and a power input jack to connect 24 Vdc power.

Not indestructible, but the best I’ve found
Color: Onyx Black - Most Durable, Color: Onyx Black - Most Durable
This thing is unexpectedly heavy for its size. My 18 month old Giant Schnauzer is obsessed with fetch but destroys every ball she gets. The other brands marketed for extreme chewers tend to last about a day or two before they’re totally shredded. She’s had this one for about 2 weeks and it’s looking rough, but still holding together for the most part. I appreciate that as it comes apart it does so in little pieces rather than large chunks. While it’s far from indestructible, it’s the strongest I’ve found so far.

Great product! Quickly became my Pit Princess's favorite toy! The size, weight, and material is perfect for a big dog. Now we have fetch ball that has proven itself to be worthy!

Balls

My dog loves chasing these balls. He seems to love the squeak! They fit the chuck it stick perfectly, and are great replacements for the originals that came with the stick.
