Once all gain adjustments are made and proper operation is confirmed, no special
considerations are required for Matica amplifiers. Aside from the front panel gain
controls, there are no user adjustments or routine maintenance operations necessary
(or available).

When powering a system on or off, it is usually advisable to turn on the power
amplifiers last and to turn them off first, so that any turn on or turn off transient
signals generated by other equipment in the system are not amplified and sent to
the loudspeakers. However, Matica amplifiersÕ protection relays have a 4 to 5
second turn-on delay which keeps the loudspeakers disconnected while the system
is powering up. These relays also disconnect the load very quickly when power is
removed from the amplifiers, thus minimizing the chance that turn-off transients
originating elsewhere in the system will be sent to the speakers.
