11 User's Manual The optional phono stage contains two independent stereo phono preamplifier inputs which are optimized for specific uses. The type of phono cartridge you are using in the turntable will determine which phono input to use.
12 User's Manual efforts on the part of the transformer designer are required, and the resulting cost will almost always be many hundreds of dollars. Less expensive transformers will be quiet, but will usually exhibit ringing, phase shift, and some low frequency distortion.
13 User's Manual Phono Connections System Configurations The following pages show some typical connections that you might make in your installa- tion. They show how the inputs and outputs of the Classic preamplifier are connected to various audio components.
14 User's Manual CD player Connections The audio output from your CD player can be connected to the preamplifier ’ s CD inputs. If your CD player has variable outputs, this will allow you to adjust the CD player ’ s output volume to match the volume of other components in your system, such as the tape deck or turntable.
15 User's Manual T ape Deck Connections The output from your Tape deck connects to the preamplifier ’ s TAPE inputs. These inputs are only selected by using the preamplifier ’ s Tape Monitor switch. The inputs of your Tape deck connect to the preamplifier ’ s TAPE outputs.
16 User's Manual Amplifier Connections: unbalanced RCA If your amplifier has RCA inputs, you can connect them to the preamplifier ’ s Main 1 or Main 2 outputs.
17 User's Manual Amplifier Connections: balanced XLR If your amplifier has XLR inputs, it can be connected to the balanced audio outputs as shown. The balanced connections are preferred, as they provide superior noise cancellation and are less susceptible to interference than unbalanced lines.
18 User's Manual Phono Inputs RIAA curve Moving Magnet input Gain = 40dB to tape out Overload = 100mV @ 1 kHz. Input Impedance = 47 Ω Noise: better than 82 dB, IHF-A, below 10mVrms at 1 kHz Moving Coil input Gain = 60dB to tape out Overload = 5.
19 User's Manual In view of the Classic ’ s input/output flexibility, the many connecting cables to and from the components which may be con- nected to it, and the large number of possibili- ti.
20 User's Manual Loud howl, squeal, or whistle. • The Tape Monitor switch is engaged while microphones (in the same room as the speakers) are connected to a tape deck for recording. • Put the cat out. Solo voices, or instruments sound thin, shrill or distorted.
21 User's Manual Finally we come to the other common source of hum problems, the signal cables and their associated plugs. Inexpensive cables often have mediocre wrapped shield- ing, so better cables may make an audible difference. And it is important that the plug at each end of every cable makes a good, tight fit in its mating socket.
22 User's Manual Changing the phono stage gain The following gain changes may be performed by experienced electronic techni- cians. Your Sunfire Dealer may be able to recommend a good service/repair shop. Factory set gain of MM Phono is 40 dB. The gain may be changed as follows: 36 dB - change R 11 and R 35 to 3.
