MODEL 110 AUDIO AMPLIFIER

Operating Instructions

GENERAL

The Model 110 Audio Ampliﬁer is designed speciﬁcally for

professional applications requiring both unequalled performance

and reliability at a competitive cost. It performs such functions

as microphone preampliﬁer, booster ampliﬁer, mixing ampliﬁer,

program ampliﬁer, line ampliﬁer, and other such functions as

required up to line levels. This unique ampliﬁer contains an

integral active isolation "transformer" which eliminates system

ground loop problems without increased cost and performance

limitations normally associated with conventional transformers.

UNCONDITIONAL GUARANTEE

When utilized in accordance with these operating instructions,

the performance to published speciﬁcations, and the operational

reliability of the Model 110 Audio Ampliﬁers are Unconditionally

Guaranteed by SPECTRA SONICS for two years from the date of manu

facture. Any returned ampliﬁer will be repaired, without charge

(except for postage), the same day received by SPECTRA SONICS.

TERMINATION

The Model 110 Audio Ampliﬁer is mounted on a compact printed

circuit card (2 1/2" X 5" X 1/2") and may be installed in a Model 201C

Card Holder. The card holder contains a Model 230 Card Connector,

which has 10 bifurcated terminal edge connectors to insure positive

contact and provides a convenient, and orderly, method of wiring,

grounding and a stable housing.
