VM1410A is a voice grade sound board which can play up to
10 different messages. It is totally self-contained and requires only a power supply, a speaker and a trigger device (such as a push button switch) to operate. VM1410A has two EPROM sockets and can store up to 8.5 minutes of
audio in 32Kbps voice quality.
Desired messages are pre-programmed into non-volatile EPROM chips by using sound development system VP880 (for digitization) and standard EPROM programmer (for programming). Sampling rates
from 24 to 64 Kbps are available for different sound quality vs. memory cost tradeoffs. Playback can be triggered by a number of devices such as push button, motion sensor and dry contact closures. There are ten trigger inputs,
one for each message. The built-in power amplifier can deliver up to 1W into a speaker, with adjustable volume control.
VM1410A is suitable for voice grade applications that do not require frequent message change or user
recordability. It is more cost effective than user-recordable models in mass production. For applications requiring higher sound quality or more flexible controls, please use QuikWave sound boards instead.
Comparison with VM1410C
Maximum memory capacity is 8M bit for VM1410A, versus 4M bit for VM1410C. But VM1410C
has individual trigger/speaker/battery connectors and a DC power jack, in additional to Sequential Mode support.
