WARNINGS USED ON THE EQUIPMENT

The lightning flash with the arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of uninsulated 'dangerous voltage' within this product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock.

FRONT PANEL FEATURES

1. INPUT: This is for the connection with the output of your instrument. The HIGH input is used with

the majority of instruments, while the LOW input has an attenuated sensitivity for use with instruments with ”High Output” pick-ups or active preamplifier circuits.

2. GAIN: This controls the amount of gain applied to the signal at the instrument input.

3. SHAPE: This controls the shape of a pre-set equalization curve applied to the signal at the input. It

influences mostly the level and ‘Q’ of the low-mid frequency response.

4. TREBLE: This controls the high frequencies of the signal in the preamplifier.

5. MIDDLE: This active control allows you to increase or decrease the middle frequencies of the signal

in the preamplifier.

6. BASS: This controls the low frequencies of the signal in the preamplifier.

7. PRESENCE: This regulates the high-mid response of the output stage of the amplifier, enabling you

to add “punch” To the sound.

8. LEVEL: This controls the level of the signal that is passed to the output amplification stage, thereby controlling the general volume of the amplifier.

9. PHONES: This is for the output to any headphone with at least 8S impedance. When this is used, the internal loud speaker is deactivated. The signal is sent to both sides of stereo headphones.

10. POWER: Turns the Amplifier on and off.

REAR PANEL FEATURES

11. MAINS CONNECTOR: This is for the connection to the included power cable. The Mains fuse is

contained in the compartment incorporated into this connector.

12. EXTERNAL SPEAKER: This output is for the connection to an external speaker with a minimum impedance of 4 Ohms.

SPECIFICATIONS

The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying this product.

GROUNDING INSTRUCTIONS

This product must be grounded (earthed). If it should malfunction or breakdown, grounding provides a

path of least resistance for electric current to reduce the risk of electric shock. This product is equipped with a supply cord having an equipment grounding conductor and a grounding plug. The plug must be plugged into an appropriate outlet that is properly installed and grounded in accordance with the local codes and ordinances.

DANGER - Improper connection of the equipment grounding conductor can result in a risk of electric shock.

Check with a qualified electrician or serviceman if you are in doubt as to whether the product is properly grounded. Do not modify the plug provided with the product if it will not fit the outlet, have a proper outlet fitted.

Output Power: 50 Watts RMS @ 4 S Frequency Response: 40 Hz - 6kHz Internal Speaker: 12”, 4 S Input Impedance HIGH: 1M S LOW: 50kS Input Sensitivity HIGH: 48mV LOW: 100mV Power Supply: 230V AC / 50Hz Dimensions: 530 x 540 x 260mm Weight: 15 kg
