The Golden Age Project PRE-73 Jr MKII is a single-channel vintage-style microphone and instrument preamplifier. The signal path uses only discrete components such as resistors, capacitors, and transistors. The input and output stages are transformer balanced, with each transformer optimized for its purpose. This MKII version features a small format perfectly suited to the UNITE MKII rack kit.

By employing vintage analog circuitry and avoiding integrated circuits, the PRE-73 Jr MKII is able to deliver a prized vintage sound with up to 70 dB of gain. The circuit in the unit is similar to the classic 1073 module with a corresponding sound character that is warm, punchy, sweet, and musical. To reduce unwanted low-end rumbles, engage the 6 dB high-pass filter at either 40 or 170 Hz. To add presence to vocals and instruments, engage the two-position AIR boost to add 3 or 6 dB at 30 kHz. The preamp can supply 48V phantom power for microphones that require it.

Features
  • Vintage-style Class-A electronics; no integrated circuits in the signal path; no surface mount components
  • GAIN switch range from 20 to 70 dB
  • Selectable two-position high-frequency AIR boost EQ, 3 or 6 dB at 30 kHz
  • Selectable 6 dB/octave two-frequency high-pass filter at around 40 (HP1) and 170 Hz (HP2)
  • Switchable phantom power and absolute phase
  • High-impedance instrument input for any sound module, electric guitar, or bass
  • Simple signal LED indicator
  • The output level control makes it possible to do fine gain adjustments and also to overload the main gain stage for more character and then lower the signal to a suitable level before the output stage
  • Combo XLR/TRS input jack and separate output XLR and TRS jacks for flexible connections
  • Insert jack for inserting EQs and other units
  • Circuit board is prepared for the Carnhill input transformer.
  • External power supply to avoid interaction with the audio circuits and transformers
  • Small format makes it possible to mount 4 units in the separately available 19-inch UNITE MKII rack kit 
  • Solid build quality will last for many years of normal use

Puppy interactive toy
Color: Orange, Color: Orange
It’s a great toy as it keeps my 5 month old puppy very entertained! It is pretty hardy and made of good material as she tries to throw it around and chew it. She does swing it around and the hard part will hit her. She doesn’t seem bothered by it tho lol good size and minimum noise When I first introduced her to it she was a little scared but now she gets excited to play with it once it finishes charging.

My Dog Is Obsessed With This Toy!
Color: Orange, Color: Orange
My dog absolutely loves this toy and plays with it every day. The moving and rolling action keeps him entertained much longer than regular toys. He loves chasing it around the house and tugging on the rope. It’s also nice because it helps burn off some of his energy indoors. The material feels pretty sturdy, and charging was easy. Definitely one of the best interactive toys I’ve bought for my dog!

Waste of Money
Color: Orange
Cool toy but my dog ate through it the second day he played with it. It is not for strong dogs. No durability. I had to throw away the orange covers and now he just throws it around.

Cool toy. Fun for all
Color: Blue
A cool toy. entertainment for the dogs but more so for the dog parents to watch the dogs reaction. Comes with an additional rope just in case, which I loved. Only side note I would say is that the fast mood could be a little faster. My Golden retriever figured out the speed in less than 24 hours and now picks up the toy to try to chew it up, instead of chasing. With him attempting to chew on the toy in the small time I give him, there are no teeth marks yet…this toy appears to be durable. We play in short increments but enjoy the toy.

Must get!, Great interaction, mind stimulation
Color: Orange
Love this my pup can't get enough. My pup loves this and is hard on it. She throws it all around chases it and guards it like it is her child. It is strong, sturdy easy to charge and fun to watch her engage with it. Definitely must have and I will buy more. It shakes and rolls around, it walks itself and engages the pup to chase. The design is spectacular. It is light weight and the noise level is typical of a toy engaging response.
