The ASM-100 expansion audio subcarrier modulator system is a one-rack unit, capable of supporting up to two remote-programmable audio subcarrier modulators. This expands the total number of subcarriers supported by the VM-100R video modulator system to six.

Expansion subcarrier modulators are locally and remotely programmable (see Option MRVA for VM-100R) via the VM-100R front panel and remote port, respectively. A special port is provided on both the VM-100R and the subcarrier modulator expansion systems for intra-system local communication.
