4. Connect an instrument to the Input jack with a 1/4″ (shielded) instrument cable.
5. With all controls fully off, turn the amplifier on by flipping the Power switch to “On.”
6. While playing the instrument, adjust the Volume knob to the preferred level.
7. Adjust the EQ knobs and switches to taste.

Front Panels

Front Panel Descriptions

1. 0 dB / -15 dB Input Switch: Use this switch to configure the optimal input level. Typically, you’ll want to use the -15 dB setting with instruments that include high output pickups or active electronics, or if you frequently see the Peak LED [13] light up.
2. 1/4″ Input: Connect a passive or active instrument to the Input jack. Use the 0dB / -15dB switch [1] to set your preferred input level.
3. Compressor: (V7 and V12) Adjust the knob clockwise to add compression to your signal, up to a 10:1 voltage ratio at maximum. Set the knob to minimum to turn the compressor off. The LED at the right lights to indicate whenever your input level exceeds the compressor’s threshold and gain reduction is applied.
4. SGT™ (Super Grit Technology™) Circuit: Use the SGT to add classic Ampeg overdrive to your signal. On/Off Switch: Toggles the SGT circuit on/off. (Alternatively, the SGT can be toggled via the rear panel’s Switch jack—when a footswitch is connected, this front panel switch is disabled.) SVT/B15 Switch: Toggles between two “flavors” of overdrive, based on the character of either the legendary SVT® or Portaflex® B-15 tube amplifiers. SGT Grit/Level Knob: This dual-concentric knob offers independent adjustment over the amount of grit (the inner control), and output level of the circuit (the outer control).
5. Power/Mute Indicator LED: This LED bar lights up blue when the amplifier is powered on, and lights up red when the Mute switch [14] is engaged.
6. Gain: Use to adjust the signal level driving the preamp.
7. Bass: Use to adjust the low-frequency level of the amplifier for up to 14 dB of boost or cut at 40 Hz. The low-frequency output is flat at the center position.
8. Midrange Frequency/Level: Use the dual-concentric knob’s outer control (Freq) to select the midrange frequency and the inner control (Level) for up to 14 dB of boost or cut.
9. Treble: Use to adjust the high-frequency level of the amplifier for up to 17 dB of boost or –14 dB of cut at 4 kHz. The high-frequency output is flat at the center position.
10. Volume: Use to control the amplifier’s overall output level. It affects the Speaker, Phones, and Preamp outputs.
11. Ultra Lo 3-way Switch: Push the left side of the switch to cut the low-frequency output –20 dB at 40 Hz. Push to the center position to disengage Ultra Lo. Push the right side to enhance the amount of low-end with a 2 dB boost at 40 Hz and –10 dB cut at 500 Hz.
12. Ultra Hi 2-way Switch: Push the right side of the switch to engage and enhance the amount of high-frequency output by 9 dB at 8 kHz.
13. Peak LED: This LED lights up whenever your input signal is too high.* (You can use the -15 dB switch [1] to reduce your input level, if needed.)
14. Mute Switch: Flip this switch left to mute the amplifier’s outputs—see the table below for mute behaviors. The Power/Mute Indicator LED [5] illuminates red when this switch is engaged. (Mute can optionally be toggled via the rear panel’s Switch jack.)

Rear Panels

Rear Panel Descriptions

1. IEC Power Cable Connector: Plug in your included IEC power cable here and connect it to a properly grounded outlet for AC power.

2. Power Switch: Use this switch to toggle amplifier’s power on (I) and off (O).

3. Speaker Output:
   IMPORTANT! Venture series amplifiers include several protective features to safeguard against overtemperature, overcurrent, and high-frequency bursts, to ensure the safe, reliable, and prolonged operation of your amplifier for years to come. If the unit goes into its protective mode, it will recover automatically within 10 seconds..

   • Speaker Out (V3): Connect from the Neutrik® speakON® – 1/4″ combination jack into an external speaker cabinet. It is preferred to use the NL2 speakOn cable connection between your amplifier and cabinet, due to the secure locking connection and superior high-current, low-noise performance. You can optionally use a standard unshielded, 1/4″ TS cable connection. Make sure the total speaker impedance load is 4 Ohms or greater.*
   • Speaker Outputs (V7 and V12): Connect from the speakON jack(s) into external speaker cabinets using NL2 speak On type cables. The two outputs are wired in parallel, and you can use either one or both.* To avoid damage to your Venture amplifier, the total speaker impedance load must be 4 Ohms or greater.
   • For example, you could connec t: Two 16 Ohm speakers (an 8 Ohm load), Two 8 Ohm speakers (a 4 Ohm load), or one 4 Ohm speaker.
   • NOTE : Always use speaker cabinets with equivalent nominal impedance when connecting multiple cabinets. Please also see the Ampeg Venture Speaker Cabinets’ documentation, available at ampeg.com/support/manuals/.

4. Phones : Connect your headphones to this 1/4″ TRS stereo output to monitor a mix of the line-level signals reaching the amplifier and audio from the front panel’s Input jack.
   IMPORTANT! Always turn the amplifier’s Volume knob down to minimum before connecting headphones to avoid potential hearing damage.
   TIP : If you want to listen and practice through headphones “silently,” disconnect the Speaker Outputs [3]. There is no harm caused to your Venture series amplifier by using it without speakers connected.

5. Aux In: Connect the audio output from line-level sources, such as a mobile device, MP3, or CD player, to this analog, 1/8″ TRS stereo input so you can play along to a practice track as you listen with headphones. The Aux In signal is heard only on the Phones output. Adjust the output of your source device for optimal Aux In level.

6. Preamp Out : (V7 and V12) Use this 1/4″ unbalanced jack to route the preamp circuit’s output signal into an external power amp. Connect to this jack using a shielded TS instrument cable.

7. FX Loop : The FX Loop Send and Return are line level.

   • Send : Use a 1/4″ unbalanced TS cable to connect to the input of an external FX processor. The Send output is affected by all controls except the Volume. Use the FX Loop Return jack [7] to feed the returned processed signals into the power amplifier.
   • Return : Use a 1/4″ unbalanced TS cable to connect to the output of an external FX processor. Alternatively, you can connect the output of a preamp or other signal source into only the Return jack to route into the Venture power amp circuit.*
   • NOTE : When using the Return as an input with nothing connected to the Send, the front panel Input jack, Gain, Comp, SGT, and EQ knobs and switches are disengaged.
   • Mix : (V7 and V12) Turn this knob to adjust the mix between the direct (Dry) and the effects (Wet) signals when the FX Loop is used. Adjust to minimum for a purely direct signal (no effect) and to maximum for a purely effected signal (no direct). The fully clockwise position is equivalent to a serial effects loop.
   • NOTE : Venture V3 amplifiers include a fixed, serial configuration FX Loop, therefore, no FX Mix control is necessary.

8. DI Balanced Output & Switches: Use this XLR balanced jack to route your amp’s output directly into the input of an external mixer or a recorder—or to an external power amplifier or powered loudspeaker. This DI output is not affected by the amp’s Volume knob. Use the Pre/Post, Pad, and Ground/Lift switches to configure the DI Output.

   • Pre/Post Switch: Toggle this switch to configure the DI Balanced Output to be tapped from either Pre or Post specific amplifier controls and components, as follows:
   • In the Pre position (up) – the DI Out signal excludes, and is not affected by, the -15 dB input pad, tone controls, SGT settings, and the FX Loop.
   • In Post position (down) – the DI Out signal includes, and is affected by, the -15 dB input pad, Gain, tone controls, SGT settings, and the FX Loop.
   • 0 / -20 dB Pad Switch: Toggle this switch down to reduce the output of the DI Balanced Output by 20 dB.
   • Ground/Lift Switch: Toggle this switch up to engage the Ground Lift, if necessary, to help eliminate hum at the DI Balanced Output.

9. Switch (TRS): Connect a 1/4″ TRS dual footswitch, such as the Ampeg AFP-2 or AFS2, to remotely toggle the SGT circuit (tip) and Mute (ring) on/off. If you connect a TS single footswitch, such as the Ampeg AFP-1, it will toggle the SGT on/off.* (Alternatively, most manufacturers’ “latching” type footswitches will also work.)
   NOTE : The front panel SGT On/Off switch is disabled when a footswitch is connected to the Switch jack. (The front panel Mute switch remains functional when a footswitch is connected.)
   When using a 2-button footswitch, a TRS cable is required. When using a 1-button footswitch, a TS cable is recommended for proper functionality. If using a 1-button footswitch with a TRS cable, a problem can occur where, upon insert of the TRS cable, the Mute circuit is engaged and cannot be overridden.

10. Poweramp In: (V7 and V12) Use this 1/4″ unbalanced jack to route the output of an external preamp directly into the Venture power amp. Connect to this jack from the output of your external preamp using a shielded TS instrument cable. The internal preamp signal is disconnected when a plug is inserted into this jack.
