SPECIFICATIONS

POWER RATING:

Less than 0.006% total harmonic distortion at any

power level up to 60 watts continuous average power per
channel into 8 ohms at any frequency between 20 Hz and
20 kHz with both channels driven.

IM DISTORTION (IHF):

Less than 0.005% from 1 to 60 watts, each channel,

into 8 ohms.

TYPICAL THD AT  60 WATTS INTO 8 OHMS:

20 Hz: 0.002%

1 kHz: 0.002%

20 kHz: 0.006%

FREQUENCY RESPONSE INTO 8 OHMS:

-3dB, 4Hz to 2OOkHz at 1 watt.

+OdB, -0.5dB, 1OHz to 4OkHz at 60 watts.

TYPICAL CHANNEL SEPARATION:

2OHz: > 75dB

1kHz: > 85 dB

20kHz: > 65dB

SIGNAL TO NOISE RATIO, UNWEIGHTED:

Exceeds 1OOdB referred to 60 watts into 8 ohms.

INPUT IMPEDANCE: 22,000 ohms

INPUT SENSITIVITY:

1.1 volts rms for 60 watts into 8 ohms.

DAMPING FACTOR:

100 to 1kHz into 8 ohms, 50 to 1OkHz into 8 ohms.

POWER CONSUMPTION:
60 watts both channels into 8 ohms: 300 VA
Quiescent: 60 VA

SIZE: 3-1/4” high plus 1/2” feet, 17” wide, 9” deep.

(83 mm high plus 152 mm, 432 mm wide,
229 mm deep.)

NET WEIGHT: 18 lbs. (8.2 kg)

SHIPPING WEIGHT: 20 lbs. (9.1 kg)

Stereo/Mono Channel Operation:

The SE120 delivers 60 watts continuous average power per

channel into 8 ohms. It can be bridged for single channel
operation producing up to 120 watts of power into 16 ohms.

Input Mode Selector:
This switch will allow the user to specify the input signal to
the amplifier.

A. Stereo Mode:

This allows the right and left channels to reach their

designated amplifier channels. This mode will deliver

more than 60 watts into an 8 ohm load.

B. Mono Mode:
The SE1 20 can be operated in a bridged mode which drives
both channels with the same signal and combines to deliver
more than 150 watts into 8 ohms. This disables the right
channel input and routes the signal through the left channel.

Construction:

The simplified construction of the SE120 improves relia-
bility and results in consistent performance. The heavy

duty case construction on the SE120 will provide years of
durability and trouble free protection.

Gold Plated RCA Input Connectors:

This provides the most accurate signal transmission and

lowest possible loss. Gold-plated terminals are immune to

signal deterioration with time that can be caused by corro-
sion in the connectors.

Speaker Output and Power Connectors:
For minimum loss power transfer, high definition and
oxidization resistance.

Protection System:

The SE120 is equipped with a unique protection system

that constantly monitors the temperature of the output

devices and takes corrective action to prevent damage to
the amplifier as a result of excessive overheating.
