Dual Channel UseUsed as a two-channel device, a lead singer and guitar player, can take the classic studio quality of the 5017 wherever they go; using the DPC for a Vocal mic pre and compressor, as well as a separate DI preamplifier. To achieve this, the blend control should be selected as fully DI (blend off), and an internal jumper can be selected to apply the compressor to the mic pre signal. When engaged, Silk mode would effect both vocal and guitar tracks, and the HPF control would effect only the mic path.
Blended UseUsed as a single channel device for instruments, the 5017 can be used to phase align, combine and compress direct and amplified signals. To achieve this, use the DI for the instrument's direct signal and the mic preamp for the speaker cabinet signal. The blend control is used for mixing direct and amplified signals to achieve the desired tonal blend between the two sources, and the variphase is used to minimize or extenuate phase cancellations between the two signals. To compress the blended signal, the internal compressor jumper must be set to the blend path (this is the default setting). This technique could also be used to create a single, mixed output of a guitar and vocals.
The CompressorBased around an LDR (light dependent resister) design, the 5017's opto-coupler compressor has been simplified to a single threshold control with auto make up gain. By default, the compressor is set to a fixed 2:1 ratio with an internal jumper to change between standard and fast time constants. To set the compressor, simply dial the threshold control down until the desired amount of compression is achieved. An LED light indicates when the compressor is active.
Vari-PhaseIn addition to the standard polarity reverse, the 5017 also incorporates a vari-phase control to adjust the phase incrementally. This control is useful any time two signals derived from the same source are combined.For instance, even with careful placement, the combination of close miced drums and overheads, can often yield hollow sounding results. By using the variable phase adjust, the direct signal can be phase rotated until the signals are naturally aligned.This technique is also extremely useful when combined with the internal blend control on instruments. A bassist, using both direct and miced signals can blend the two into a single output, using the vari-phase to reach an optimal alignment. By adjusting the phase in the 5017, the musician or engineer can find the absolute best mic position without regard to the phase relation to the direct signal.With the 5017, the Portico sound is always within reach.
FeaturesTwo Channel OperationWith two transformer coupled outputs, the 5017 has separate line outputs for the DI/Blend and Mic signals when the blend control is set to fully DI. The mic output is always independent.SilkMuch could be written about this feature, suffice to say, that it gives a subtle option to enhance sound quality in the direction of vintage modules. The silk button reduces negative feedback and adjusts the frequency spectrum to provide a very sweet and musical performance. We suggest you try it and make your own judgment.Mic GainMic gain is from 0dB to 66dB. Overall gain to restore the apparent program levelDI GainDI Gain is from 0dB to 30dBDI inputBalanced or unbalanced Hi-Z input for instrumentsHigh pass filterThe high pass filter is a valuable aid in any signal chain but particularly so in a microphone preamplifier. Signals below 80hz can be attenuated at a rate of 12db / octave, getting rid of building rumble, air handling motor hum etc.Phantom powerProvides 48v phantom power to microphones. Controlled by a switch on the back of the unit.Phase invertReverses the polarity of the mic inputThresholdWhen signals exceed the "threshold" level, the gain is reduced at a controlled 2:1 ratio, with attack and release time constants set to standard or fast depending on the internal jumper setting.IndicatorsIndicators on the 5017 denote signal presence and clipping on both DI and mic signals, as well as compressor activation.Internal jumpersTwo internal jumpers in the 5017 can be set to change the compressor from the mic channel to the di / blend channel, and to change the compressor time constant from standard to fast.

When will I receive my shipment?
We ship on business days (Saturday, Sunday, and holidays are not business days). Packages ship from Mississippi, Nevada, New Jersey, or Ohio -- we cannot guarantee that any product will ship from a specific warehouse. Expedited Shipping (1-Day Air and 2-Day Air) is the only way to guarantee that you will receive an item within a certain time frame. Delivery estimates for expedited shipping options are listed on the product page for the item in question. All expedited shipments are delivered Monday-Friday.
Ground Shipping typically takes 1-4 business days from the date of shipment (for orders within the 48 contiguous United States). Residential ground and Free 2-Day shipments are delivered Tuesday-Saturday. Commercial ground and Free 2-Day shipments are delivered Monday-Friday. Make sure to select the proper address type for your address in checkout, as delays may occur if your selection is incorrect.
For APO/FPO customers, all orders ship via USPS. Expedited shipping is not available. Tracking for these orders is not available.
For customers shipping to a PO Box, the order may need to be shipped via USPS. For this reason, expected delivery dates cannot be guaranteed.
Do you ship to my location?
For most products shipping to the continental United States, customers may choose Ground, 2-Day Air, or 1-Day Air delivery. We also ship to Alaska and Hawaii; however, due to carrier restrictions, we cannot ground-ship to those states.
In addition, we ships to the following destinations, though some restrictions apply:
- Puerto Rico
- U.S. Territories
See instructions below for how to search the site by our eligible shipping destinations.
Note: We cannot change a shipping address on an order after it has shipped. If an order is returned because it couldn't be received at the listed shipping address, we will accept the return but will not refund the shipping charges.

What about customs fees?
Please be aware of customs fees such as taxes and duties, which are not included in our shipping charges. Customs fees vary from location to location. Please check with your local customs office for more information on the fees in your area. If you refuse to pay these fees, your order will not be delivered. We cannot refund shipping charges if an item is returned due to refusal to pay fees, and a restocking fee may be applied to cover the cost of return shipping. Customs fees are non-refundable.
Which items ship immediately?
Most orders ship the same business day your order is placed when you place a valid order before the shipping deadline.
Immediate shipment is available Monday-Friday. A valid order placed before 5 p.m. EST will ship the same day when using Ground or Free 2-Day shipping. Ground and Free 2-Day shipping orders placed after 5 p.m. EST will ship the next business day. Many orders using an expedited shipping method (2 Day Air or Next Day Air), and placed before 10 p.m. EST, will ship the same day.
Shipment and availability information updates from our warehouse to our website almost in real time. We are highly confident of the status of each item when you view a page. However, we do not reserve inventory being viewed or even placed in shopping carts, so we cannot guarantee an item's availability until you have placed your order. In particular, if you have been in the checkout area for more than about 10 minutes, we do recommend that you refresh the page to get the most current inventory prior to checking out.
What is a valid order?
A valid order is for a valid item at a valid price, placed with a credit card with complete and verifiable address and other information. Details.
Does immediate shipment mean immediate delivery?
Once an order is shipped, our carriers (Federal Express and UPS) typically guarantee a service time for when the order will be delivered to you. Our carriers have a very good record of delivering at their promised service time. We will ship immediately, and on all items, we will refund expedited shipping charges if the carrier's service levels for your chosen shipping method are not met.
If a product is in stock, is there any reason it will not ship immediately?
Exceptions are very unusual, but here are some examples of reasons that might prevent us from shipping immediately:
- Warehouse, call center, or web operations lose power or telecom connectivity.
- Warehouse, call center, or web operations lose capability due to adverse weather (blizzard), safety threat, or other factors.
