  • Cab Zone LE (Lite Edition)


    FIR Cabsim kit for guitar or bass

    Every guitar and/or bass player has their own favorite amps and cabinets. Yet however much you love a stack’s sound, you will probably have trouble hurling it on and off the stage, let alone playing it at home (unless you don’t mind your family and neighbors going deaf).

    The solution for gigging players comes in the form of cabinet simulation units (cabsims), which let you approximate your favourite cabinet’s sound. Analog cabsims were pretty good for plugging into the PA but used to lack detail in their sound — and they only modeled a limited number of cabinets.

    Next came digital cabsims, and their incredibly detailed sound pushed cabinet simulation to a whole new level. They are, however, quite expensive and not pedalboard-friendly enough.

    This eventually led us to creating the Cab Zone LE — a highly detailed yet inexpensive digital IR-based cabinet simulation device. The unit comes with 10 built-in impulses and allows the user to upload 10 more via microSD card.

    The Cab Zone LE is equally usable on stage, at rehearsals, and at home (through speakers or headphones of your choice). The best thing is, it costs less than a typical guitar pedal!


    Key Features of the Cab Zone LE

    Enclosure:
    • In order to reduce the price, the unit is shipped as an assembled and fully set-up board. You can make your own enclosure or 3D-print it (the model is currently in the works).
    • The unit comes in fully working condition: connect your instrument to the input and speakers to the output, plug in the PSU, and you are ready to go.
    • The Cab Zone LE can be used without any enclosure as long as the current-conducting part is properly insulated.

    Connectivity:

    • IN: instrument-level input with switchable attenuation (volume cut to prevent input overload).
    • THRU: unprocessed parallel output to go into an audio interface, amp, etc.
    • OUT: main output to go into the mixer or powered speakers.
    • AUX: 3.5 mm stereo input for external audio (mp3 player, drum machine, etc.). The signal from the Aux input only goes to the headphones output; this way, the Cab Zone LE can be used for monitoring while recording or for playing along with a metronome.
    • 3.5 mm stereo headphones output.
    • Power input (9-15VDC).
    • MicroSD card slot.

    Impulses:
    • The device comes with 10 built-in impulses, including classic (Fender, Marshall, Orange), metal (Peavey, Mesa), and two bass ones.
    • 10 more impulses can be uploaded via microSD card.
    • Impulses from a microSD card are in use as long as the card is inserted. If there is no card in the microSD slot, the built-in impulses are used.
    • If a blank card is inserted, a folder system containing the built-in impulses is created on it. This way, you can transfer the built-in impulses to a different software environment.
    • Impulses are selected via an 11-position dial. The 0 position equals bypass (there is no passive bypass switch).
    • Impulse format: .wav mono 24bit 48kHz WAVE PCM1, uncompressed.
    • Impulse length: 940 samples (19.58 ms). You can upload longer impulses but only the first 940 samples will be used.
    • A FAT32-formatted microSD card of any capacity (1Mb to 32Gb) is required for impulse upload.

    Auxiliary/upcoming functionality:
    • The Cab Zone LE allows to update the firmware of the ADAU1701 signal processor. With this auxiliary function, users can upload custom effects (such as chorus or flanger with fixed parameters) via microSD card. The complete description of this function will be published later.
    • For potential future applications, the device can be connected to a display via four wires.

    Controls:
    • Volume control (affects all outputs, including the headphones output).
    • 11-position impulse dial (full CCW is bypass, full CW is impulse 10).
    • 3-position switch for input attenuation.

    There is no separate bypass switch. The bypass is digital, engaged by selecting impulse 0. Use the main output to go into the mixer and the Thru out to go into the amp. The digital bypass is present so that you could directly compare the sound with and without cabinet simulation.


    Some facts about the device
    • Originally a tiny cabsim with just two impulses, the device later turned into a 30-impulse stereo monstrosity before finally becoming the Cab Zone LE in its current form.
    • The Cab Zone LE can be used with the Shift Line Twin/Olympic tube preamps (MkI and MkII), as well as with the Shift Line Beta preamp. A separate 9-15VDC PSU is required for the Cab Zone LE.
    • The device can also be used in the FX loop of the Twin/Olympic/Beta preamps.
    • The Cab Zone LE and a pair of powered hi-fi speakers or monitors can serve as a replacement of a combo amp for home use.
    • The device works great with dirt pedals. Now you can play your favourite metal riffs through your home sound system!
    • If a blank card is inserted, a folder system containing the built-in impulses is created on it. This way, you can edit the built-in impulses and/or transfer them to a different software environment.
    • he Cab Zone LE is based on the ADAU1701 digital signal processor chip and allows to update its firmware via microSD card (currently in beta testing).
    • The lag between instrument signal input and processed output is under 1.2 ms.
    • The cabsim’s attenuator works well with small combo amps (around 15W) and some more powerful ones. However, the device is mostly designed to be used with pedalboards and small amps.
    • The 3-position switch selects between various attenuation levels: 0, -6dB and -20dB (approximately 1x, 2x and 10x volume reduction, respectively).
    • The unit’s own noise level is very low.
    • The board poses no threat of burns or electric shock to the user: the voltage is 9V or less. To prevent dust from getting onto the board, you can build your own enclosure of cardboard, plastic, or any other non-conductor. Enclosure models for 3D printing are currently in the works.
    • Board color and other details that don’t affect the sound are subject to change.
