Overview:
The ISA 220 Session Pack provides all you need to record your session with precision and Focusrite sonic performance. It features many of the original circuits of the flagship ISA 430 Producer Pack along with some new features of its own. It also features the same digital option as the ISA 430, providing you with a high quality digital route direct from the 220 into your digital recording system.

The PRE-73 Mk2 pre-amp and the FC3 condenser microphone in one bundle. The bundle also includes Golden Age P1 Pop Filter, Proel RSM180 mic stand and Proel CHL250 5m cable. |
Having had great success with the PRE-73 preamp, we have received many requests for a version for the 500 eries rack format. We are therefore happy to present the PRE-573, expected to start shipping in late September.
The PRE-573 is a one width module that has the sound and the features that made the PRE-73 so successful and a few additional ones.
The circuit still uses the preamp and output section from the classic 1073-module, adapted to work in the api rack format. It has a total gain range from -15 to +80 dB. The 10 - 70 dB range is handled by a turn switch and there is a separate toggle switch to select an additional 5 or 10 dB gain. The input can be configured to accept line level signals by another switch, the gain is then lowered by about 25 dB and the input impedance increased to about 15 kohm.
The input impedance of the mic input mode can be switched between 1200 and 300 ohm. Phantom power and phase reverse is also selectable by front panel switches.
An added feature, using the same circuit as in the PRE-73 DLX, is the active DI-input with a high input impedance of about 1,5 Mohm. The output signal from the active DI circuit passes through the input transformer for some extra character.
The DI-input is very flexible since it can be changed to a purely passive one by a front panel switch. The DI input is then exactly the same as in the PRE-73 Mk2 where the signal is feed directly into the second gain stage, bypassing the transformer and with an input impedance of about 100 kohm.
These two DI-options makes it possible to get different tones from electric instruments and the passive DI input mode is more suited for injecting active units like sound modules.
A new feature is the switchable AIR mode that adds a small boost above 10 kHz that peaks at 2 dB at about 35 kHz.
A simple but effective signal and overload indicator is offered by a single LED that starts glowing red at about +4 dBu and then increases its intensity up to the maximum output level.
The PRE-573 has a dedicated insert connector at the back allowing it to interface with other GAP 500 modules. The insert can be activated by removing a jumper connector at the back of the module.
The second Golden Age Project module for the api 500 rack will be the EQ-573, expected to ship in November 2012. The EQ-573 consists of the inductor based high pass filter section and the 3-band eq section from the classic 1073 module with some added frequencies. These two modules together will offer a fully fledged 1073-module in a compact format at a very low cost.
There is a second jumper at the back of the module that selects 600 ohm termination on the output. The standard mode is termination on, since it gives the flattest response when the PRE-573 is used with modern line inputs that typically has an input impedance of 10 kohm or more. The user can chose to remove the jumper and deactivate the termination resistor, this will increase the level above 10 kHz and create a peak in the response for an even more pronounced "Air" effect.
The output is transformer balanced and fully floating and can drive a 600 ohm load up to level of about 28 dBu.

Features Superlative sound Studio quality mic preamp Total control - Input Gain, EQ contour, Output Gain, Overload indicator Multiple output connectors XLR/jack combo input Switchable 48 V DC Phantom Power for condenser Mics Compact, computer friendly package Needs no external power supply ARX is proud to introduce the e-pre - the ultimate microphone pre-amp for hard disk recording, designed by audio professionals, not computer engineers. The all-new e-pre is so much a part of your system that it fits right into a spare 5?" slot in your computer case! It's the perfect tool for all your day-to-day recording requirements. No equipment racks to plug in, no masses of cabling to connect - the e-pre is ready and waiting when you need it. The e-pre is a studio quality microphone pre-amp using the same internal components as high end mixing consoles, built into a compact, computer friendly package. It has controls for: Input Gain - fully variable from 10dB through to 60dB to suit all types of microphones, plus switchable 48 V Phantom Power to enable condenser microphones to deliver their best. A Contour control for EQ sweetening, providing fast, easy access to a whole range of useful EQ curves Output level control - fully variable to match the e-pre's output to the input of the sound card. From -10dB consumer cards through to +4dB for professional sound cards, the e-pre can handle it. Multiple output connectors match up with any kind of sound card, including mini jacks, standard jack, RCA (phono) plugs, and even a connector to link to the internal CD ROM audio input of your sound card (if fitted). We've even fitted a 12 VDC input connector on the rear to enable the e-pre to run from an external power supply if required (eg for use with notebook computers or stand-alone use).
Any way you look at it, the e-pre by ARX is the total professional microphone pre-amp for all your hard disk recording needs
