PS301

The PS301 is the perfect combination of analog/linear working in conjunction with digital circuitry. Its linear supply section with a toroidal transformer paired with linear regulators nearly eliminate all stray radiation. The PS301 works well with other sensitive lighting and audio gear nearby. Its built-in microprocessor monitors temperature, voltage, and the current status of both the input and output. At 24 volts DC, power is thoroughly regulated and automatically decreases when needed. Current limiting in addition to short-circuit protection prevent hardware damage if a connection error or cable failure were to occur. A discreet built-in fan turns on when needed to decrease the overall temperature of the unit. The PS301 also features a program input that can be channeled to any or even all of its three circuits. The unit also functions in either the 120VAC or 240VAC range.

Features

  • Ideal combination of analog/linear with digital circuitry
  • Virtually eliminates stray-field radiation
  • Works well with others sensitive audio and lighting gear close by
  • Features a quiet built-in fan that turns on automatically when needed to cool unit
  • Since each PS301 circuit is individualized, an issue with one does not impact the others
  • Microprocessors control all of the switching, routing, and supervision capabilities, while the audio paths and power supply stay true to their analog character.
  • The PS301 can be used with any unbalanced 200 ohms party-line intercom components.

Power Supply

  • The PS301 can be used with any unbalanced 200 ohms party-line intercom components.
  • The components and microprocessor which monitor and adjust the power supply's performance are separately mounted on their own circuit board, as far as possible from any heat source.
  • At as low as 100VAC, the secondary voltage will remain at 24VDC while the available current will be slightly reduced from 2.4A continuous to 2.0A continuous.
  • The transformer has primary windings for both 120VAC and 240VAC (50/60 Hz) and allows wide deviation from those voltages without any effect on performance.
  • The voltage and fuse are changed on the rear panel.
  • The microprocessor will also adjust the percentage of the 2.4A (continuous) current that is allocated to each circuit, depending upon the load on each.
  • Reports the status of each circuit to LED indicators on the front panel: The top, green LED reports that 24VDC is being delivered to the system. The lower 3 red LEDs flash when that circuit is experiencing an overload and stay on constantly when the circuit has been shorted and therefore shut down until the problem is solved.
  • The monitoring and control functions include automatic adjustment of the termination impedance when the
  • circuits are combined, adjusting to brown-outs or sudden drops in line voltage, monitoring the temperature of the heat sink and switching the cooling fan on when required
  • After a circuit problem is eliminated, the PS301 continues to function normally with having to re-boot
  • Since each PS301 circuit is individualized, an issue with one does not impact the others
  • Able to perform alongside nearby electronic devices without interference
  • The result of this combination is unmatched flexibility, structural strength, and clean, rich audio.
  • Microprocessors control all of the switching, routing, and supervision capabilities, while the audio paths and power supply stay true to their analog character.
  • The PS301 is a 3-circuit Power Supply with a specialized hybrid composition.

Shipping

Shipping Options

We offer free ground shipping on most items for orders $300 and over, $20 for flate rate ground shipping on orders from $150 to $299.99, and $14 flat rate ground shipping on most items for orders under $149.99. *paints, liquids, and large volume items like boom bases (very heavy) or fake snow (not heavy, but very large) may incur a shipping surcharge. Exclusion of items from Free and Flat Rate shipping is at ProAdv's discretion. Offer is currently limited to Lower 48 US States.

We ship to North American addresses. Note that there are restrictions on some products, and some products cannot be shipped to international destinations, or even certain states depending on the item and state or local laws.

Our full policy is in our Terms and Conditions page.
Pandemic Availability Notice

Please Note: Due to unprecedented raw material and component shortages for finished goods throughout our industry, lead times for items that aren't currently in stock are longer than normal and cannot be guaranteed at present. Equipment needed by a firm date must be noted at time of order. While VLS cannot guarantee delivery by those dates, we will work with our suppliers to do everything possible to meet deadlines. We apologize for the inconvenience and appreciate your patience.

Same Day Shipping Cutoff time
 
(Due to Pandemic-related availability issues, this policy is currently suspended)

Online orders received by noon Eastern time typically ship the same day. If your delivery due date is critical please note your due date in the order messages at checkout, and then contact us.

Why Noon? Well, while we stock quite a few items in our warehouse, many items we have dropshipped by our vendors. They need time to process the order, so to ensure that we can get the order to the vendor and give them enough time to ship it out the same day, we need to get the order to them as early as possible in the day.

Shipping Rating

Please also note that the shipping rates for many items we sell are weight and dimension based, as this is the method that FedEx and UPS use to rate the package's cost to ship.

Returns Policy

We understand things happen and items occasionally need to be returned. To make things as hassle-free as possible, we have dedicated pages about our Returns Policy (what’s eligible to be returned) and our Return Process (how to go about returning eligible items)
