FCC Compliance Statement:

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

Fuse Information

There are various types of fuses, and replacing them with different types may cause malfunction, electric shock, or fire. Be sure to confirm you are replacing the correct fuse with electrical rating and specifications.

Example: T3AL250V

The following symbols and their meanings are illustrated:

• T: Symbol indicating relative fusing time / current characteristics. T denotes a Time lag type, F denotes a Fast-acting type.
• A: Rated current.
• L: Symbol indicating the blocking capacity. L denotes Low cutoff capacity, E denotes Medium cutoff capacity, H denotes High cutoff capacity.
• V: Rated voltage.

Hookup Diagrams

The following diagrams illustrate common setup configurations for the Heritage SVT-CL amplifier and speaker cabinets.

Standard Setup

This setup connects the Heritage SVT-CL amplifier to a single speaker cabinet. The amplifier's speaker output (Speakon or 1/4") connects to the speaker cabinet's input.

Diagram shows the SVT-CL amplifier connected via its speaker output to a single speaker cabinet labeled "Speaker Cabinet A".

Parallel Setup

This setup connects the Heritage SVT-CL amplifier to two speaker cabinets simultaneously. The amplifier's speaker output connects to the input of Speaker Cabinet A, and Speaker Cabinet A's output connects to Speaker Cabinet B's input.

Diagram shows the SVT-CL amplifier connected to Speaker Cabinet A, which is then daisy-chained to Speaker Cabinet B. Both cabinets are connected to the amplifier.

Daisy Chaining

This setup connects the Heritage SVT-CL amplifier to two speaker cabinets. The amplifier's speaker output connects to the input of Speaker Cabinet A, and Speaker Cabinet A's output connects to Speaker Cabinet B's input. This is similar to parallel but emphasizes the chain connection.

Diagram shows the SVT-CL amplifier connected to Speaker Cabinet A, which is then daisy-chained to Speaker Cabinet B. Both cabinets are connected to the amplifier.

Note: Always use speaker cabinets with the same impedance in parallel setups and when daisy-chaining. For all setups, using the amplifier's Speakon® Output to connect to a cabinet's Speakon Input is recommended, but you can alternatively use the amplifier's 1/4" Speaker Output to a cabinet's 1/4" Input.

Front & Rear Panels

Front Panel Layout

The front panel of the Ampeg Heritage SVT-CL features controls for instrument input, gain, tone shaping, and master volume, along with power and standby switches.

The front panel displays the following controls from left to right: 1. 0 dB Input jack, 2. -15 dB Input jack, 3. Gain knob, 4. Ultra Hi switch, 5. Ultra Lo switch, 6. EQ knobs (Bass, Midrange, Frequency, Treble), 7. Master knob, 8. Standby/Power/Fault LED indicator, 9. Standby switch, 10. Power switch.

Rear Panel Layout

The rear panel provides connections for power, fuse access, bias adjustment, and various audio outputs for integration with other equipment.

The rear panel includes: 11. AC Line In (IEC power connector), 12. Fuse holder, 13. Polarity Switch, 14. Bias Section controls and LEDs, 15. Ext Amp Out jack, 16. Balanced Out jack, 17. Preamp Out jack, 18. Power Amp In jack, 19. Impedance Selector switch, 20. Speaker Outputs (Speakon and 1/4" TS).

Front & Rear Panel Descriptions

1. 0 dB Input:

Connect a passive instrument to this input jack.

2. -15 dB Input:

Connect an active instrument to this input jack.

3. Gain Knob:

Varies the intensity of the signal sent to the preamplifier.

4. Ultra Hi:

Enhances the amount of high frequency output.

5. Ultra Lo:

Enhances the amount of low-end output.

6. EQ Knobs:

Boost or cut the level at certain frequencies to enhance the sound (Bass, Midrange, Frequency, Treble).

7. Master:

Adjusts the overall output level.

8. Standby/Power/Fault LED:

Multi-function LED illuminates red in Standby mode, green when powered on, and flashes between red and green when the amp detects a fault.

9. Standby Switch:

Turns the Standby mode on and off. Standby allows the tubes to warm up or remain warm without high voltage applied.

10. Power Switch:

Turns the overall system power on and off.

11. Power Connector:

Connect the supplied AC power cord to this IEC jack.

12. Fuse:

Provides overload and AC line surge protection.

13. Polarity Switch:

Helps to remove electrical buzz.

14. Bias Section:

These two controls and set of LEDs allow the user to properly bias the power amp.

15. Ext Amp Out:

Use this jack to send the preamp signal to another amplifier.

16. Balanced Out:

Feeds an external mixer or recording setup with a balanced audio signal.

17. Preamp Out:

Direct post-master preamp output for use with an external power amp.

18. Power Amp In:

Connects directly into the internal power amp for use with an external preamp.

19. Impedance Selector:

Use this switch to match the output impedance of the amplifier to the speaker(s).

20. Speaker Outputs:

Speakon and 1/4" TS outputs for connecting speaker cabinets.

Getting Started

1. Read and understand the included “Important Safety Instructions.”
2. Ensure the Power and Standby switches are both in the "down" position before making any connections.
3. Push the line cord securely into the amplifier's IEC connector (11) and plug the other end into a grounded AC outlet. The amplifier is designed to accept the appropriate voltage as indicated near the IEC connector.
4. Connect an instrument to the Heritage SVT-CL Input jack (1 or 2) using a shielded 1/4" instrument cable. Connect the amplifier to speaker cabinets using non-shielded speaker cable with Speakon or 1/4" TS ends.
5. With the Master and Gain controls fully off, turn on the amplifier by pressing the top edge of the Power switch (10). The Power LED (8) will illuminate. Wait 30 seconds for the tubes to warm up.
6. Press the top edge of the Standby switch (9) to exit Standby mode.
7. While playing the instrument, adjust the Gain (3) and Master (7) knobs to the preferred level.
8. Adjust the EQ knobs (6) and switches (4, 5) to taste.
