Get to know them!

A rock-solid direct box that stays out of your way, the Franklin Audio DI-80 offers straightforward performance with zero hum or tonal coloration. Brandishing eight identical channels, this bulletproof passive DI houses custom-wound transformers, fusing full-band frequency response with flawless isolation. For instrumentalists, its high input impedance feels natural to play through, and its industrial enclosure fits seamlessly in your rack. Whether you plug in a borrowed synth, a spare bass, a rented vintage drum machine, or a rarely used effect processor, the DI-80 puts ample channels of pristine, high-headroom passive DI conveniently at your fingertips. Moreover, since it’s passive, it requires no power. The DI-80 lets you keep your oft-used gear patched neatly into its back panel, and it offers label-friendly space above each channel for scribble strips. Practical per-channel Ground, Polarity, and Pad switches are also onboard. The DI-80 represents direct injection at its finest; it’s simple, reliable, and engineered for a lifetime of faithful service.

The payments equal the amount financed divided by the number of months in the promo period, rounded up to the next whole dollar. These payments may be higher than the payments that would be required if this purchase was a non-promo purchase. During the last month(s) of the promo period the required monthly payment may be reduced due to the prior months’ rounding. Regular account terms apply to non-promo purchases.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
