TECHNICAL FOCUS: PRODUCT IN DEPTH

In operation, you obviously get some

movement noise but it was all extremely

low; apart from the homing/initialization

noise, the loudest item was the gobo

wheel when indexing/spinning at speed,

but even that was only 41dBA at 1m.

Homing/initialization time

The smartMAC took 41 seconds to

power up from cold and 38 seconds to

do a “warm” reset. It was well-behaved

during reset, and kept its shutter closed

until everything was in its final

programmed position.

Electronics and control

This is an interesting part of the design.

The absence of fans meant that anything

heat-sensitive has to be kept well away

from any potential heat sources. That

means keeping all electronics away from

the head, with its lamp, and the top box,

with its power supplies. The yoke is the

obvious spot and indeed that’s where the

main board and drivers are located (Fig.

16). The power supplies (switching motor

supply and magnetic lamp supply) are

both mounted in the top box underneath

the yoke with heatsink fins each side

(Fig. 17). Access to everything is simple

and neat—as long as you still have that

Torx driver.

There is the ubiquitous four-character

menu display system (Fig. 18), albeit

amber rather than red, with a good

selection of options and test routines to

set up and use the unit. Martin has given

the smartMAC a strong set of stand-

alone routines and macros, allowing you

to program and run simple routines on

the unit from this menu panel. Again, I

think this reflects the target audience. I

had no problems operating or using any

of the options.

Construction & serviceability

I’ve mentioned construction throughout

the review—overall, the smartMAC is a

very tidy unit that has obviously had a lot

of attention paid to aesthetics. The cable

handling and removable base mounting

plate both show that this is a unit

designed to be seen by the public in an

architectural situation.

From a service perspective, the

construction is familiar and

straightforward to follow. I had no

difficulty in disassembling (and, more

importantly, reassembling) the

smartMAC, just from previous experience

of automated lights. It should present no

problems to an experienced operator.

As I’ve said before, unfortunately, the

format of these reviews doesn’t allow

testing during long term, so I cannot

comment on reliability; however, I had no

problems during the time I had the

luminaire in my shop.

So, there we have it, the Martin

smartMAC—a neat and elegant unit with

a slightly limited set of features, but the

undoubted plus of silent operation. Is

this the light for you? As always, I just

present the measurements and you get

to decide…
