The stereo, all-tube MP-2A from A-Designs is a dual-channel audiophile-quality microphone preamplifier that is designed to be versatile and sonically flexible. The preamp will work with any ribbon, condenser, or dynamic microphone, as well as instruments such as guitars, bass, and keyboards via the DI input. The MP-2A uses no integrated circuits and relies solely on discrete components such as EF86 input tubes, 6N1-P output tubes, Audience capacitors, custom-wound Cinemag output transformers, and hand-crafted point-to-point wiring.

Each channel provides up to 60 dB of clean, low-noise gain, a -20 dB pad, and two Tone switches that provide four distinctive possible sonic signatures. Additional features include Neutrik XLR connectors, true VU metering, 48V phantom power, polarity reverse switches, and front panel Hi-Z input jacks. The preamp's fixed-gain amplifier/output attenuator topology provides a wide "sweet-spot" for any microphone or instrument and captures material with clarity and transparency. The MP-2A ships with a standard IEC power cord.

Not super durable but good squeak while they work
Color: Multi Squeaker Balls, Size: Large, Style: 4-Pack
My dog loves these but they break very quickly. I've got an older set that was incredibly durable, but these all stopped squeaking/got holes after the first or second play session

Heavy chewer approved.
Style: Ball, Size: Medium (Pack of 1)
My pomsky will destroy a toy in minutes. Ropes, and the "indestructible" nylon type stuffs are no match for my furry shark. This ball has stood up to him like David. He loves the crunch and it is so much more tolerable than a squeaker. These will be a staple in his toy box - Chuckit toys are really the most durable dog toys I have found in three years.
