systems and outdoor installations, a utility model will serve the client’s needs just as well, and decrease the equipment costs.

Approached methodically and logically, the choosing of a mixer/ amplifier for a distributed sound system can be a painless and efficient process. Don’t select a “pro spec” unit when all you need is a utility amp; you’ll be wasting money and it won’t do the job any better. As we have shown, by applying a little analytical thought and care, you can satisfy clients’ needs while keeping costs in line. And that’s what the sound contracting business is all about.

When the Job Calls For ProAnnounce!

When the system specification calls out for a routed zoned system then ProAnnounce is the best avenue. There are a few key decisions to make to determine the basic equipment makeup of the installation.

First, the design process and site survey should have established the basic signal structure of the installation. This will define if a DRM4000 8x2 unit is sufficient or if one or more of the powerful DPM4000 4x4 routers are called for. If the installation calls for a DPM4000 unit you must determine if more than a single DPM4000 is needed and what input cards are required. Second, if additional zones beyond the basic 4 are being used then the DCS 400 system is required. This allows for a large, extended, relay controlled routing network for paging. Third, if automatic messaging is desired then a DMM4650 may need to be added. This will provide additional flexibility for prerecorded announcements and signals. Finally, if any additional external controls are being added (remote audio volume or source switching for example) then the appropriate DCS control module will be needed.

The DRM4000 vs. the DPM4000

In order to determine which cpu is best for an installation the designer needs a good working understanding or each of the units capabilities. To better understand the difference between the DRM4000 and the DPM4000 an overview of each is provided below.

DPM4000 4x4 Matrix Router

The DPM4000 is essentially a 4 x 4 digital matrix with added DSP capabilities. Actually, when you factor in the internal alarm/chime functions, message stacking, and pre-recorded message functions it is more like a 7 x 4 matrix. Processing in the form of level and EQ is provided on each of the four external inputs to the system. In addition, level and optional delay is provided on each of the four outputs in the system. Analog compression is also available on certain input cards, as well as, the paging stations. The DPM 4000 can be configured to perform tasks based on a variety of control inputs. Likewise the DPM 4000 can provide a variety of control outputs. Examples of these inputs and outputs might be: a contact closure from a fire alarm results in an alarm and voice message automatically sent to the loudspeaker system, pressing a button on a paging station or wall control raises or lowers a video screen and turns on or off the video projector, a maintenance worker uses his cell phone to turn the lights on or off in a given area of a building, an amplifier failure is detected, a backup amplifier is switched into operation and maintenance personnel are notified of the failure. The possibilities are only limited by one’s imagination and ingenuity. The DPM 4000 can be configured for a variety of audio routing tasks in addition to the normal paging applications. The unit is especially suited for background music applications in such venues as restaurants, shopping centers, and specialty stores. The DPM 4000 can even be used for very small room combining applications (up to four rooms).

DRM 4000 Mixer

Unlike the DPM4000, the DRM4000 can be used with very little preprogramming. Many of the functions are externally selectable or adjustable. The DRM4000 can be used either in a stand- alone mode or in conjunction with the DPM 4000. The DRM 4000 can be used to enhance the DPM 4000’s input and output capabilities. The DRM 4000 features eight stereo RCA inputs, four
