Mackie TT24 Uživatelský manuál stáhnout pdf

ver the past several years

we’ve witnessed a digital

revolution at the top end of

the live sound arena. Digital consoles

have now proven themselves robust

and roadworthy, and as a result are

now common for both large tours and

installations.

We’re also seeing digital consoles in

smaller applications. However, getting

digital benefits like recall, flexible rout-

ing, “super” channel strips with gates

and compressors as well as equaliza-

tion (and don’t forget internal effects

processors!) can get pretty expensive.

Further, some of the smaller digital

boards were originally developed for

recording applications, with features

and interfaces often better suited to

the studio. And, limited input/output

(I/O) capacity forces the live user to

add card slot expanders just to access

the power of the on-board DSP.

Set against this backdrop, Mackie

sought to develop a mid-size digital

mixer for live sound applications, with

the result being the new TT24.

We kicked off the design process for

the TT24 by listing all potential features

and then eminating those not inherent-

ly related to live mixing. Our team

focused on two primary goals: Develop

a control surface that would allow

instant access to any primary mix func-

tion within two hand movements, and

provide a “digital edge” to the tools

needed for mixing live every day.

process, helping to keep us on the
