RM81 MixMax
The RM81 is an eight channel mixer in a single rack space intended for a
variety of sound reinforcement applications. Each of the eight channels has
an XLR microphone input, as well as a 1/4" unbalanced input. The 1/4"
jacks may be internally jumpered to become channel direct outputs. If
configured this way, the direct outputs' signal is derived from the post
position of the channel's Volume control. Each channel has individually
switchable +12 VDC phantom power. An RCA unbalanced Aux/Bus input
has been provided for cascading other RM81s, and an RCA unbalanced
Prefade output is used to connection to the other RM81 Aux/Bus input.
The Main output for the RM81 is a 1/4" balanced TRS jack.
The RM81 MixMax is ideal for board rooms, church choirs, etc. Any
application where many microphones need to be mixed together, and space
is limited - the RM81 is the right choice.
