The SE22 is a two-channel, solid-state, equalized

preamplifierlline amplifier designed to provide the

highest quality disc reproduction for broadcast and

recording studio applications. While primarily de-

signed for stereo use, it may be very effectively

utilized for two separate monophonic channels.

Features include:

Precise RIAAINAB equalization.

Completely solid state.

High-impedance inputs properly match al-

most all magnetic disc reproducers.

Individual high- and low-frequency equal-

ization trimmers on each channel.

Individual channel level controls.

Extremely low noise and rf susceptibility.

Full line output capability.

CONTROLS, CONNECTIONS,

AND OPERATION

Inputs

lnput jacks (phono type) are located on the rear

panel and designated "A" and "B." Channel level

controls and output terminals are correspondingly

lettered. Any magnetic pickup designed for opera-

tion with a 47,000 ohm input termination may be

directly connected to these jacks.

The SE22 may be used either as a stereo pre-

amplifier or as two separate monophonic channels.

If a stereo cartridge is to be used (with its channels

Printed

U.S.A.

paralleled) as a monophonic source to one channel

of the

SE22, the SE22 input should be shunted with

47,000 ohm resistor or the high frequency trimmer

should be readjusted for proper high frequency

equalization.

Outputs

Output terminals appear on the rear panel as

shown in Figure C. Outputs are balanced and

designed to feed a 150 ohm or 600 ohm line.

Channel Level Controls

These controls are located on the front panel

designated as

Level" and

Level." They are

used to adjust the overall operating level of the

SE22 and to balance the individual levels of the

two channels.

Response Trimmers

To allow for balancing the response of the two

channels of a stereo cartridge, or of two mono-

phonic cartridges, high- and low-frequency re-

sponse, trimmers are provided for each channel.
