Equitech Son of Q Sr. Power Conditioner - Black

The budget-conscious descendent of the flagship Model Q power conditioner

Product Description

The Son of Q is offered in 3 different sizes.  The original Son of Q model has a 1500 Watt capacity and plugs into any standard 15-amp 120-volt wall outlet as does it's smaller sibling, the Son of Q Jr., which has a 1000 Watt AC load capacity.  The largest of the three, the Son of Q Sr. can drive 2000 Watts of load but it requires a full sized 20-amp outlet such as the kind found near most modern kitchen countertops. 

Son of Qs have a simple yet elegant appearance.  They feature an anodized aluminum front panel that is available in black or silver.  On the front panel there are 2 LED indicator lights, one above the input power switch and one above the output standby switch that monitor power status at the input and at the output of the unit.  The input power LED doubles as a TVSS status light that indicates active surge protection when lit.  On rare occasion if it stops working and the output light still works, that means that the surge protector has taken a big hit and expired.  In the rare event that this happens, the Son of Q transformer's grounded Faraday shield maintains excellent backup surge protection until the TVSS can be replaced.  On the back panel, there are 12 outlets provided.  A GFCI outlet is independent from the front standby switch and is constantly left turned on for use with components that require continuous power for a clock or to maintain memory.  Of the 10 remaining outlets, 6 (white) are for analog components such as self-powered monitors, amplifiers, pre amps, crossovers etc. and 4 (gray) are specially filtered outlets for digital gear.  A circuit breaker on the rear panel protects the system from overload and from potential short circuit fire hazards in electrical power cords and downstream connected equipment.  


Open the lid on a Son of Q and see for yourself how well made these systems truly are.  There is no skimping on how Son of Qs are designed and built.  All three models use isolation transformers with an enormous mass that rival competitors' products with twice the current rating.  The Son of Q Jr. is modestly rated at 1000 Watts with a transformer that compares to our competitors 20-amp systems.  The Jr.'s heart is massive but the Son of Q Sr. is nearly twice the size.  Son of Q transformers are designed to operate with an extremely low impedance and a very low magnetic flux density.  This means that under load, they operate with a lot of magnetic headroom left in reserve and they can transfer current quickly upon demand to amplifier power supplies when a large transient occurs.  Their magnetic shields allow for use near sensitive equipment such as single-coil pickups and tape machines.  


Most of today's project recording studios do not require a high level of continuous current to operate efficiently.  The power supplies simply do not have the mass and size that require a constant high current power source but at times they do demand high current in short bursts, especially class AB monitor amps and self-powered speakers.  The Son of Qs like the Model Qs are one of the few power products in the marketplace that routinely maintain a high power factor when used with high current pulse demand loads.  They actually enhance playback quality rather than get in the way and make an amplifier sound compressed.  Son of Qs are designed to be a perfect fit in project studios with small to medium sized boards, an outboard rack or two, a keyboard setup and self-powered monitors (or modestly sized monitor amps.)  Like the Model Q, their performance specifications are rated for top engineers and professionals in the industry but their price is more affordable.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.
Michael D.
From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
Thomas W.
I am a new customer of yours. You guys provided me the absolute best deals in ordering all the equipment to power my brand new recording studio. Your customer service is amazing and i will always deal with you from here on out.
