CAL OPERATING INSTRUCTIONS

VERTICAL BEAM STEERING

All CAL loudspeakers include vertical beam steering of

±30 degrees in 1-degree increments. The steered beams

can also be of any supported vertical spread (from 5 to

30 degrees).

SPLIT BEAMS

The CAL 64 and CAL 96 models include split beam cover-

age modes to aim sound toward two destinations or to

avoid reflective surfaces such as a balcony. The split beams

can also be configured with the desired vertical spread (see

“Vertical Beam Spread” on page 20) and steering (see “Ver-

tical Beam Steering” on page 21).

CAL 64 Center Split Beams

The CAL 64 model includes a center split beam coverage

with the top beam emanating from the top 32 drivers and

the bottom beam emanating from the bottom 32 drivers.

Figure 2 shows a CAL 64 with center split beams, each with

5-degree beam spread (no steering). Also illustrated are the

beams’ acoustical center points.
