DIT-MCO Iunior speaker and junction box.

This unit uses a 4"x6" speaker, giving greater cone area than is sometimes available. And it is almost entirely tamper-proof. The speaker grill is backed by a fine wire mesh to prevent damage to the speaker cone from pencils, nail files and other improvised weapons sometimes thrust wantonly through the louvres. An L-pad volume control has a brass shaft and ferrell. A coiled cord, anchored in the case with rubber inserted constant pressure wire clamps, connects the speaker and junction box.

The junction box is of heavy cast aluminum, mounted on the speaker post by means of two Allen 10-24 cup point set screws. Of streamlined construction, it contains the line transformer which is not only edicient but contains taps to

match ten diderent line impedance values. These leads from the transformer are readily available by means of heavy terminal-strip screw lugs. In addition, the transformer has two independent speaker windings as secondaries. If one speaker should fall, the other would not be affected.

For the operator interested in a lowerpriced and slightly smaller speaker unit, there is a model available which is approximately 6"x43/g"x21&" deep. This junior model features brass-shaft, wirewound volume control, weatherproof speaker unit, soldered magnet, cast aluminum case, and baked hammerloid Finish. Supplied with cast aluminum junction box and line transformer, the entire unit mounts on any 1%" pipe or 2" post.

In parking areas not attainable by conventional in-car speakers, the utilization of a standee speaker will enlarge the effective range of drive-in sound. The speaker unit of the standee model is of waterproof construction and the cast aluminum case, being fabricated from one of the toughest of the industrial metals, can withstand practically any amount of weather and patron abuse.

Approximate size of the speaker is 8',X10t";/:HX5" deep. Said to be absolutely tamper proof, it incorporates a brass shaft, wire-wound Lepad type volume control, which can be pre-set to any desired volume level. The unit is designed to mount on any ll/zl/ pipe or 2" post.
