Intercom Systems

|
| Q: |
How does an intercom system work?
|
| A: |
In general, a residential intercom has two normal functions, (1)
To page another person for short information conversations. For instance,
"John you are wanted on the phone." "Okay, I'll be
right there." (2) Monitoring a room to make it easier to move
around the home and still be able to monitor the activities in that
room. More advanced systems have become popular as a result of added features
such as music distribution, door chimes, more versatility and better
overall performance. |

|
| Q: |
I have an older model intercom system. Can I replace just
the master unit and keep my room stations? |
| A: |
No. Technology has changed so much through the years that older
speakers simply cannot function with the more advanced technology
of today's master units. |
| |
|
| Q: |
Can I monitor from my intercom? |
| A: |
Yes. All Linear intercom systems have monitoring capability. Linear
intercom systems can monitor one room into the rest of the house,
or the rest of the house into one room, or any combination in between.
|
| |
|
| Q: |
Can I talk from room to room? |
| A: |
Yes, but keep in mind that most residential systems are "all
call" systems (i.e. when you speak into one speaker your voice
travels to all other speakers that are turned "on" throughout
the home). |
| |
|
|
Q:
|
Can I select which rooms hear the radio?
|
| A: |
Yes, for the dmc1 and dmc3-4. The dmc1 and dmc3-4 have room control switches that enable
you to select various functions for each remote speaker. On those
systems without individual room control switches, you simply turn
the volume control on the desired speaker from full volume to "zero."
|
| |
|
| Q: |
Can I change the radio stations from my room speakers? |
| A: |
Yes. There are a couple of different ways to change radio stations
from room speakers. With any Linear system that allows for the use
of "Remote Scan" (RS) speakers (MC302,
MC602, MC702, MC960), radio stations can be changed from
the individual room stations. In fact, it's as simple as pressing
the "scan" button. A second method is to use an RF Remote Control. This works
like the transmitter of your garage door opener. If you are within
approximately 100 feet of the master unit, you can change the stations
by pressing a button on the hand-held transmitter. |

|
| Q: |
Is an intercom-only system available? |
| A: |
Yes. The DMC-10 is an intercom-only system. |

Speaker Systems
|
| |
|
| Q: |
Can I use ceiling speakers for all applications? |
| A: |
Generally, no. Speakers, like lighting, can "flood"
sound or they can "spot" sound. The type of speakers, the
placement and the power are all influenced by what application is
needed.
|
| |
|
| Q: |
How many speakers can I connect to my amp? |
| A: |
First take a look at the wattage of your amplifier. Figure a minimum
of 20 watts of power per pair of speakers. Divide the wattage of the
amplifier by 20 watts per pair to find the maximum number of speaker
pairs that can be impedance matched for the amplifier. (Example: 100
amplifier - divided by - 20 watts per room = up to 5 pair of impedance
matched speakers.) |
| |
|
| Q: |
What is the difference between a woofer and a tweeter? |
| A: |
A "woofer" is a speaker designed to respond best to lower
music frequencies while a "tweeter" is a speaker designed
to respond best to high music frequencies. |
| |
|
| Q: |
What is a coaxial speaker? |
| A: |
Coaxial describes the placement of the tweeter and subwoofer with
respect to the design of a speaker. Coaxial is indicative of a speaker
whose tweeter is directly in front of its subwoofer on the same axis.
This saves room and usually allows the size of the speaker grill to
be smaller while providing a wide frequency range.
