6.4 mm jack socket balanced line input; sensitivity – 30 dBu; overload protected; front panel recessed gain control

Slave I/O

6.4 mm jack insert point for connection of SP5 phase shifter
0 dBu signal can be used for recording

OUTPUTS

 

Drive voltage

7.12 Vrms (10V peak) at maximum output current

Drive current

• 3.5 Arms (5 Apk) continuous 1 kHz sine wave
• Short term peaks >7 Apk
• Front panel recessed control
• Drive current indicated on 4-LED display in 3 dB increments

Loop connector

Wieland ST17/2 (supplied)

Loop Monitor

Provides access to actual audio signal in loop via a 3.5 mm stereo headphone connector on front panel

AUDIO SYSTEM

 

Freq. response

80 Hz to 6.5 kHz

Distortion

THD+N

Automatic Gain Control

The AGC is optimised for speech. Range >36 dBu
Front panel recessed input level control

Metal loss correction

Corrects system frequency response due to metal structures in a building. Gain constant at 1 kHz, adjustable gain slope from
0 to 3 dB per octave
This does not compensate for signal loss from metal structures, which can be significant

ADDITIONAL FUNCTIONS

 

Fault Monitoring

Three LED fault indicators on the front panel:
• Overload – delivering over the rated current
• Overheat – unit is too hot (mutes output signal)
• Loop error – short circuit / open circuit error

Ancillary

To supply Ampetronic ancillary units
±15 V DC 0.15 A power outlet on rear panel

Cooling

Cooling is by natural convection from product casing
