Topic: GuitarJack F.A.Q.
What differentiates the GuitarJack from headset input jack devices, and why is it priced higher? (See GuitarJack FAQ to compare GuitarJack with other dock connecting devices like the JAM.)
Products that connect via the headset input jack may have a 1/4" input for guitar and a headphone out, but that's where the similarity with GuitarJack ends.
• Adjusting the analog input level, before it is digitized and clipped, is the most requested feature by FourTrack users. GuitarJack allows for 60 dB of analog input gain (72 dB with the 12 dB pad) controlled via software .
• GuitarJack can communicate with applications via the dock connector device, which line in devices are unable to do.
• GuitarJack is able to record in stereo because the dock connector has stereo line in. All devices that plug into the headset jack of an iOS device are limited to mono.
• The dock connector is an unprocessed line input. Apple applies measurable equalization to the headset input that was optimized for voice - not necessarily what you want when recording other instruments.
• Impedance matching is important to produce optimal tone. GuitarJack has a selectable impedance, Hi-Z and Lo-Z, which allows it to work with a variety of instruments and mics.
• GuitarJack has 2 inputs (1/4" mono and 1/8" stereo) that can be used simultaneously to record both an instrument and a microphone.
• GuitarJack's electronic design and components are premium quality: Nickel-plated, solid brass Switchcraft jacks with 10,000 insertion MTBF; aluminum case, etc.
• GuitarJack has less input to output crosstalk than the headset jack.
• GuitarJack passed Apple certification, FCC and CE testing, which is required for dock connecting devices. Headset input devices may not have gone through this rigorous testing.
