Incorporating four channels of renowned preamplification, independent silk controls, two channels of DI inputs, and an M-S Decoder into a 1U enclosure, the 5024 is a workhorse equipped to enhance the front end performance of any digital or analogue recording system. Each channel of the Portico 5024 is based around the custom transformers and class-A circuitry found in the best-selling 5012.

In addition to 72dB of gain, the 5024's mic pres include individually selectable phase, mute, phantom power, a selectable frequency high pass filter, and the Silk circuit which yields the rich warmth and presence of the renowned classic designs. Channels 1 & 2 of the 5024 feature a high-Z input designed for instrument level sources. Channels 3 & 4 feature an M-S switch, which enables Mid-Side decoding without the use of multiple console channels.

Low Noise, Low Distortion Operation
Much care was given in designing the 5024 to produce as little noise and non-harmonic distortion as possible. Carefully implemented signal paths and Class A operation are a large part of the 5024's sweet, whisper-quiet performance.

Portico 5024 Mic Pre Features

Microphone Input
The microphone input is balanced but not floating, using a Transformer-Like-Amplifier (T.L.A.) configuration with a toroidal Common Mode Rejection Low Pass Filter that excludes frequencies above 150 kHz. The T.L.A. is followed by an actual input transformer designed by Mr. Neve that permits a full +25 dBu input signal to be handled at unity gain without an input pad over the whole audio spectrum. This innovative solution combines the advantages of both an electronically-balanced and true transformer input. When the Phantom voltage is switched off, this input serves as a very high quality line input with an impedance of 10K Ohms.

Line Outputs
The main output signal comes from the output transformer secondary which is balanced and ground free. A ground free connection guarantees freedom from hum and radio frequency interference when connected to a balanced destination such as the input to another Portico module or a high quality ADC. Maximum output level is + 26 dBu, which provides a large margin over and above the likely maximum requirement of any destination equipment to which the 5024 is connected.

Mic Gain
A 12-way precision rotary switch covering from Line (0) and Mic from 0 to 66 dB in 6 dB steps.

Trim
A continuously variable pot provides +/- 6dB level adjustment on each channel

In and Thru 1/4" Jacks
These 2 jacks on both CH1 & CH2 are used for DIRECT INJECTION (DI) or INSTRUMENT inputs, and are simply paralleled and wired together. Inserting a plug into either jack breaks the normal MIC input and the user has the full range of MIC GAIN and TRIM. These jacks have a 3 mega ohm input impedance that will provide less loading (better highs) than most DI boxes. The sheer amount of clean gain that is available makes these inputs extremely versatile.

Silk
This feature 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.

M/S
The M/S button engages Mid-Side decoding on channels 3 & 4. Channel 3 level controls the mid signal, and channel 4 level controls the side signal.

Instrument Inputs
Balanced or unbalanced Hi-Z input for instruments using the Mic Pre's gain circuitry.

Level Meter
-30 dBu to +22 dBu with reference to the output

Mute
Cuts of the output signal post metering and pre Buss Output. Be sure to mute the outputs before engaging phantom power.

High Pass Filter
The High pass filter is a valuable aid in any signal chain but particularly so in a microphone preamplifier. Signals below 30 or 90 Hz can be attenuated at 12dB / Octave, leaving the range above this unaffected. This gets rid of building rumble, air handling motor hum etc.

Phantom Power
Provides 48V phantom power to microphones

Protect your investment with the Long & McQuade Performance Warranty.

Warranty can be a very important factor when making a buying decision. Because repairs can be very expensive in terms of parts and labour costs, manufacturers usually only provide one year limited warranties that generally only cover items that malfunction due to a manufacturer’s defect. With an important purchase such as a musical
instrument or piece of studio gear, however, many people want to have the peace of mind in knowing that their investment will be protected should the product no longer be performing at 100%.

Because of this, Long & McQuade provides our customers with a FREE one-year Performance Warranty on most of our products. The Long & McQuade Performance Warranty supplements the manufacturer’s warranty to ensure that our customers receive complete “no hassle” warranty coverage within their first year.

How does the Long & McQuade Performance Warranty differ from most manufacturers' warranties?

Performance Guarantee - normal wear and tear is covered, so your product will be performing as well as the day you purchased it for the entire duration of the coverage.

Product Replacement - if your product cannot be fixed or costs too much to fix, we will replace it with the equivalent model for no additional charge. If this is not possible, a full refund will be provided.

No Lemon Policy - your product will be replaced should the same problem occur multiple times.

Convenient - easy drop off and pick up of the product at any Long & McQuade location.

Guitar Setup - Guitars purchased at Long & McQuade come with 1 free setup, to be redeemed within 1 year for new guitars and 90 days for used guitars.

Loaners Available - a loaner product may be given while the product is being repaired.

Power Surge Protection - your product is covered even if damaged from a power surge.

Accessory Coverage - any peripheral devices or accessories that come with your product (i.e. foot pedal, case) are also covered.

Commercial Use Coverage - music and recording professionals who purchase gear for “heavy-use” commercial purposes will still be covered.
 

Long & McQuade reserves the right to restrict the purchase of additional years of Performance Warranty.Used products come with a 3-month Long & McQuade Performance Warranty. Some products (i.e. computers, software, cymbals and other items) are covered only by the manufacturer‘s warranty. Consumables (i.e. strings, reeds, woodwind pads, drum sticks, batteries, tubes, cross faders) are excluded as they are designed to be replaced. Accidental or cosmetic damage is not covered. Speakers damaged by overpowering are generally not covered. Our coverage does not provide compensation for loss of use. As of June 2018 the Performance Warranty is no longer transferable. The warranty is only valid in Canada.

Purchasing additional years of coverage

If you are interested in receiving this coverage for longer than one year, you have the option of purchasing additional years of the Performance Warranty. The pricing is as follows:

NEW products: 4% of selling price to double the warranty from 1 year to 2 years. 4% for each additional year.

USED products: 4% of selling price to increase the warranty from 3 months to 1 year. 4% for each additional year. Pricing for used electronic products is 4% of the original new selling price.

GUITARS: 4% of selling price to double the warranty from 1 year to 2 years. 4% for each additional year. $45 maximum. An additional free setup is not included with additional purchased years of Performance Warranty.

BAND and ORCHESTRAL instruments: $40 up to $2,000 selling price. BRASS and STRINGS: 2% of the selling price after $2,000. WOODWINDS: 4% of the selling price after $2,000.

Some manufacturers provide warranties for longer than 1 year; however, these are usually limited warranties that do not provide the same coverage as the Long & McQuade Performance Warranty. Customers interested in more complete and convenient (but not necessarily longer) coverage are still able to purchase additional years of the Performance Warranty.
