PT 2.1

Indicators

Enable: This red indicator shows the on/off status of the low voltage power supply.

Signal/IOC: Each channel has a two color indi- cator that ﬂashes green to show signal pres- ence and yellow if the ampliﬁer causes distor- tion of 0.05% or more.

Input/Output

Input Connector: Balanced 1/4-inch phone jacks and XLR connectors in parallel.

Input Impedance: Nominally 20 K ohms, bal- anced; 10 K ohms, unbalanced.

Output Connector: Two sets of color-coded binding posts.

Output Impedance: Less than 10 milliohms in series with less than 2 microhenries.

DC Output Offset: Less than 10 millivolts.

Output Signal

Stereo: Unbalanced, two-channel.

Bridge-Mono:Balanced, single-channel. Chan- nel 1 controls are active; Channel 2 controls should be turned down and not used.

Parallel-Mono:Unbalanced, single-channel. Channel 1 controls are active; Channel 2 con- trols should be turned down and not used.

Protection

Power-Tech .1 Series ampliﬁers are protected against shorted, open or mismatched loads; overloaded power supplies; excessive tempera- ture; chain destruction phenomena; input over- load and high-frequency blowups. They also protect loudspeakers from input and output DC, as well as providing protection from turn-on/ turn-off transients.

If operating conditions are unreasonable, the patented ODEP circuitry proportionally limits the drive level to protect the output transistors, particularly in the case of elevated temperature. A thermal switch imbedded in the transformer protects the power supplies from overload. In the rare event that a transformer overheats, the thermal switch removes power, waits until the unit has cooled to a safe temperature and then resets itself.

Turn On: Four-second delay with no dangerous transients. Contact us if you need to change the delay.

Construction

Durable black ﬁnish on steel chassis with spe- cial “ﬂow-through” ventilation from front to side panels.

Cooling: Internal heat sinks with forced-air cooling for rapid, uniform heat dissipation.

Dimensions: Standard 19-inch (48.3-cm) rack mount width (EIA RS-310-B), 3.5-inch (8.9-cm) height and 16-inch (40.6-cm) depth behind the mounting surface.

Approximate Weight: Center of gravity is 6 inches (15.2 cm) behind front mounting sur- face.

120 VAC, 60 Hz Units: 33 pounds (15.0 kg) net; 37 pounds (16.8 kg) shipping weight.

International Units: 35 pounds, 12 ounces (16.9 kg) net; 38 pounds, 13 ounces (17.6 kg) shipping weight.
