Description

Now in its second generation, the ISA 428 Mk II incorporates four of Focusrite’s renowned mic pres in a simple-to-operate 2U enclosure, placing four mic preamps, instrument inputs and line ins at your fingertips. The original Focusrite mic pre was designed to suit the microphones of the time; today’s model makes one small change, adding three additional input impedances to the classic ISA110 setting, allowing you to match any microphone, old or new, and access a wide range of sounds, from the character and warmth of a vintage mic to the clear transparency of a modern design. Or you can experiment and bring out just the qualities you want.In addition to the mic inputs, there are four front-panel instrument inputs making the ISA428 Mk II ideal for overdubs in the control room with no need for a DI box. On the back: four line inputs and switchable insert points on each channel to allow routing via external signal processors. There’s also a versatile, vintage design variable high-pass filter to control what’s going on at the bass end. And finally… accurate, 6-LED meters to tell you exactly what’s going down. Optionally available for the ISA428 Mk II is a precision eight-channel A-D converter with 122dB dynamic range and superb jitter performance – ideal for simple interfacing with your DAW.

Four ISA series transformer-based preamps
ISA series mic preamps have been the producers’ choice on countless hit records over the last two decades.

Eight-channel optional A-D converter
Four additional A-D converter inputs allow eight channels of high quality conversion, with a dynamic range of 122dB and jitter performance below 250 picoseconds.

Selectable impedance
Ideal for mic matching or extended microphone creativity. Settings include the ‘Vintage ISA110’ setting, providing the original focusrite signature sound.

There’s no doubt that when it comes to power, musicians have it bad. Whether it’s modern modeling amplifiers, or vintage synthesizers, bad power is gonna be heard throughout your signal. And it’s everywhere — in homes, on stages, and especially in many rehearsal rooms. Black Lion Audio has been trusted for years for modifying the best gear and making it even better, and that’s what it took to create the PG-P: taking industry-standard designs, and improving them to the point of peak performance. After creating an entire lineup of industry-best power conditioners, Black Lion Audio felt it was time to give the world proper portable power. The PG-P might look like a run-of-the-mill surge protector, but in reality it’s a studio-class power conditioner — PG-P doesn’t just provide more noise filtering than other portable conditioners, it provides the same noise filtering found in the majority of the world’s rack-mount power conditioners! Your gear deserves the best power, and Black Lion Audio took great care in making sure the PG-P delivers just that — thanks to it’s PG-P Filtering Technology. The PG-P is built using premium Panasonic capacitors, due to their superior execution in eliminating high frequency noise that robs equipment of its peak performance. In testing, this has provided an average of 3x the noise filtering of other portable power conditioners at the same price point. Six wall-wart spaced outlets provide studio-grade power on the go; perfect for any musician’s rig!

The Suhr Reactive Load delivers a simple solution to capture all of the warmth, and dynamics of your sound, without the hassle of miking a speaker cabinet during a live or recorded performance. The Reactive Load takes the place of your speaker cabinet in your signal chain. It provides an 8Ω load for your tube amplifier (maximum 100 watts), and produces a balanced and unbalanced signal that interfaces with recording devices, effects, and power amplifiers. The Suhr Reactive Load is the perfect link between your amplifier and computer audio recording interface. You can use the Reactive Load with your existing library of speaker impulse responses (IR) for the most realistic direct recording experience possible. Traditional resistive load boxes will safely load your amplifier, but they also alter the tone, dynamics, and response of your amplifier. Real speakers do not have a fixed resistance across the entire frequency spectrum. Real speakers are reactive. The impedance curve of the Reactive Load has been painstakingly tuned to react like a speaker. Your amp will never know the difference. The Reactive Load is dedicated to being the absolute best load box possible with zero compromises, and therefore does not include speaker emulation. You can use the Reactive Load with your speaker-sim or impulse response of choice, and benefit from the natural response, dynamics, and touch sensitivity of your amp. The Suhr Reactive Load features a balanced or unbalanced line level output. The INPUT is optimized for the 8 ohm output of your amplifier and the THRU jack can be connected to a physical speaker cabinet. If a physical cabinet is connected to the THRU jack, the Reactive Load’s internal load is bypassed and the amp will see the load of the physical cabinet. SPEAKER INPUT IMPEDANCE: 8 Ohm DI / LINE OUT LEVEL: +4 dBu at 7 watts input, maximum level setting BALANCED LINE OUTPUT IMPEDANCE: Less than 6KΩ UNBALANCED LINE OUTPUT IMPEDANCE: Less than 6KΩ MAXIMUM RECOMMENDED INPUT POWER: 100 Watts RMS ROHS COMPLIANT: Yes DIMENSIONS: 8.8" (W) x 8.9" (D) x 3.6" (H) WEIGHT: 6.6lbAs with ELI’s other signal processors, the Lil FrEQ Equalizer takes a somewhat unique approach to its job. Instead of daisy chaining several equalizers and frequency processors, we combined most of the sound sculpting tools an engineer needs into a compact single rack space box, while still offering the highest performance of any design in its class. Eight Sections of Processing There are eight sections of processing – what other EQ offers that? Even better – in addition to a master bypass, each of the Lil FrEQ’s sections features its own dedicated bypass switch, letting you instantly A/B the effect of each section as you adjust and fine-tune them. HIGH PASS – The High Pass section is a really easy to use sharp filter that cuts all content below one of eight preset frequencies from 30-330 Hz. This filter is very steep and has a special shape that prevents frequencies from thinning out just above the cutoff point. The corner frequency is selected using up/down buttons, and indicated by LEDs that glow softly when the section is bypassed, and brightly when the section is engaged. HIGH & LOW SHELVING – These two knobs function similarly to the familiar “bass and treble” tone controls found on many consumer audio playback systems; however, these are designed to a much higher performance standard, providing exceptionally smooth and musical boost and cut on the high and low frequencies. PARAMETRIC EQ – The Lil FrEQ has four sections of fully parametric EQ (LF, Lo Mid, Hi Mid and HF), with each section featuring individual gain, bandwidth (Q) and frequency controls.  It may be the cleanest parametric EQ section ever produced, operating below .0007% THD (Total Harmonic Distortion) even at extremely high audio levels. Try finding those specs anywhere else! DS (DYNAMIC EQ) – The DS section provides the highest performance, easiest to use, and possibly most natural sounding “De-esser” ever built.  This powerful tool combines tunable filters with a compressor-like circuit that can help contain and control excessive high frequency content such as sibilants or other sharp transients, especially in the absence of other lower frequency content.  It can also function as a one of a kind soft knee High Frequency limiter, which is one of the main things responsible for the Lil FrEQ becoming the go-to vocal EQ for engineers everywhere.  It has been used on many acclaimed albums and major live performances all over the world, becoming the “go to” EQ for key tracks like lead vocals, snares, and bass.  There are now dozens of hit record vocals that were processed thru the Lil FrEQ. Frequency Response: 5 Hz to 140 kHz on transformerless inputs and outputs. Transformer output 10Hz to 110 kHz. Dynamic Range: 120 dB from maximum output (.1% clipping) to minimum output. Greater than 110 dB signal to noise. Distortion: Ranges between .00056% and .005% depending on mode and settings. DS section has THD < .005%. I/O: DC coupled inputs and outputs and one transformer coupled output. Dynamic Time Constraints: Attack is approximately .5 ms. Release .04 sec fixed internally. Power Consumption: 15 Watts Max. Metal Chassis: single height 1.75″ high, 10″ deep, 19″ wide.
