Guided Tour - Servo-260 / Servo-170 Rear Panel
1: AC input - Connect the supplied standard 3-pin “IEC” plug here.
2: Fuse holder - In the Servo-260, insert a 6 amp, 250 volt fuse here for 115
volt operation, or a 3 amp, 250 volt fuse for 230 volt operation. In the Servo-170,
insert a 5 amp, 250 volt fuse here for 115 volt operation, or a 2.5 amp, 250 volt
fuse for 230 volt operation. In both models, we recommend the use of normal (as
opposed to slow-blow) fuses.
3: Push-Spring output connectors (left/right) - Use these to connect the
Servo Amplifier to loudspeakers. Wiring is red hot, black ground—be sure to
observe these to maintain correct phase correlation.
4: 1/4" Unbalanced output connectors (left/right) - Alternatively, these can be
used to connect the Servo Amplifier to loudspeakers. Wiring is tip hot, sleeve
ground—be sure to observe these to maintain correct phase correlation.
5: Heat sink - Make sure this anodized aluminum heat sink is unobstructed
when the amplifier is powered on. In particular, when the Servo Amplifier is rack-
mounted, we recommend that you keep the rear of the rack open in order to
release heat. If your rack does not have a removable rear, space should be left
open on the front of the rack cabinet, especially immediately above the Servo
Amplifier—remember, heat rises!
6: Unbalanced input connectors (left/right) - If you are using unbalanced
wiring and connectors, connect incoming signal to these unbalanced RCA-type
jacks (wiring is tip hot, sleeve ground). The Servo Amplifier accepts input levels
of any strength but needs at least 0 dBu to achieve maximum power.
7: Balanced input connectors (left/right) - Connect incoming signal to these
electronically balanced 1/4" TRS (Tip/Ring/Sleeve) jacks, wired as follows: Tip
hot, Ring cold, and Sleeve ground. Use balanced three-conductor cabling and
TRS plugs wherever possible (unbalanced two-conductor plugs can also be
inserted into these inputs, but you’ll get better signal quality and less outside
noise and hum if you use balanced lines). The Servo Amplifier accepts input
levels of any strength but needs at least 0 dBu to achieve maximum power.
