Speaker Outputs; Effects Loop - Rivera Sedona Owner's Manual

Note: Always turn the amp off and wait about five minutes before replacing a fuse. This allows the
parts to cool and high voltages to dissipate.
For 100VAC and 115VAC versions, the Mains Fuse is: 3 Amp, 250 Volt Slo-Blo type (size 3AG,
or MDL)
For 230VAC versions, the Mains Fuse is: T 1.6A (time-delay, 5mm x 20mm size)
HT Fuse
The power amplifier circuit has its own fuse for protecting the output section from short circuits and
transient current peaks that exceed the normal current draw. These conditions are usually caused by
a bad tube. When a short circuit or transient peak causes the fuse to blow, the output tubes should
be checked and replaced, if necessary.
For 100VAC and 115VAC versions, the HT Fuse is: 1/2 Amp, 250 Volt Slo-Blo type (3AG, or
MDL)
For 230VAC versions, the HT Fuse is: T 500mA (time-delay, 5mm x 20mm size)
Repeated blowing of this fuse is a clear indicator of a defective output tube.
Always use the correct fuse value when replacing the HT Fuse.
If the Mains Fuse or the HT Fuse repeatedly blows, refer your amp to your local RIVERA dealer or
contact us at (818) 767-4600 or support@rivera.com for further service assistance.

Speaker outputs

Two 1/4" Speaker Output phone jacks are provided. The first is for the Celestion G12T-75 full
range driver. The second is for the tweeter. The first jack of the pair labeled Speaker 1 must be
used first, as there is a built-in safety standby switch that will interrupt the power amp section from
drawing DC current if a plug is not inserted into the jack. (This feature is also provided for
technicians to easily and accurately adjust the amplifier's bias by measuring the DC idle current.
See the Bias Adjustment section for more details.)
The second jack is intended to drive an internal tweeter or tweeter input of the Sedona Extension
Enclosure. The switch labeled Tweeter On/Off functions on this jack.
