Audio Quality and Flexibility with a Touch of Grace

Our Product Research Team

Get to know them!

Combining all the functionality modern sound engineers and musicians require, the Grace Design m108 provides eight channels of pristine microphone preamplification, front-panel hi-Z inputs, cutting-edge A/D conversion, low-latency monitoring, a reference-grade headphone amp, flexible digital outputs, adaptable local or remote control, and more. For the m108, Grace Design took the best features of its successful m802 and packed it all into a sleek 1U interface. At Sweetwater, we are taken with the ease of use and outstanding audio quality of the Grace Design m108, and that's attributable to the company's cutting-edge technologies.

Cutting-edge technologies onboard

The m108's transformerless "transimpedance" microphone preamp effortlessly resolves complex audio waveforms for recordings with impressive depth and clarity. The onboard A/D conversion is remarkably analog sounding, while its next-gen s-Lock PLL serves up a clean, jitter-free sample clock whether you're clocking from Dante clock or external WC. And you'll enjoy outstanding jitter performance when the m108 is connected to your computer.

Effortless, intuitive operation

Grace Design built the m108 for effortless and intuitive operation. Its clean front panel employs a rotary push-push encoder for navigation. Dedicated push buttons handle core functionality (phantom power, polarity reverse, channel grouping, and meter peak clear). An easy-to-read OLED display keeps you informed of metering, peak status, and channel gain, plus it provides the system setup menu. Whether you're in the studio or recording remotely, you'll appreciate the m108's fluid ease of use.

Configurable for your present and future needs

From the get-go, the m108 is a flexible standalone microphone preamp/converter with eight output channels of 192kHz ADC via AES, USB, and ADAT. Avail yourself of its integrated serial or MIDI control, and you can configure it for big-channel-count remote systems, remote controlled from the optional m802 remote control unit, from Pro Tools, or from Grace Design's m108 control computer app. Further, an optional Dante interface is available for network audio configurations. You can even add m108 to an existing m802 system, as the m108 control protocol is backward compatible.

Select manufacturers may require that only the manufacturer’s products qualify towards the minimum purchase amount needed to be eligible for promotional financing. Otherwise, an invoice that meets the minimum purchase amount and contains at least one qualifying manufacturer product is eligible for promotional financing. No interest will be charged on promo purchase balance, and equal monthly payments are required on promo purchase until it is paid in full. 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. New Accounts as of 07/31/2025: Purchase APR is 34.99%. Penalty APR is 39.99%. Min Interest Charge is $2. Existing cardholders: See your credit card agreement terms. Subject to credit approval.

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.
