1. Input Jack: This is a ¼-inch, 2-conductor input for plugging in your instrument. It is intended for guitar but will accept
other instruments as well.
2. Volume: This control determines the overall volume level of the amplier. Due to the simplicity of the Defender 5H’s
all-tube circuitry, a wide range of tones can be obtained with the use of this control alone.
For example, when set in its lower ranges, the sound is clean and snappy. As the Volume control is turned up, light
overdrive is generated by the amp’s all-tube circuitry. This overdrive occurs naturally and is not created by any internal
distortion circuit. As the Volume control is turned higher (clockwise), you’ll hear increased natural drive and compression
that is great for crunchy rhythms and sustaining guitar solos. In essence, the Defender 5H generates classic overdriven
tube amp tone but at lower, more manageable volume levels. (Although you may be surprised by the amount of volume
that the Defender 5H can generate, so watch your ears!)
3. Power Switch: This dual-function component is both an ON/OFF power switch and a status indicator light. When
illuminated, it shows that your amplier is ready to be played. To turn your amplier on, press switch upward. To turn
amp off, press switch downward.
Note: After the power switch is turned on, the tubes must warm up for approximately one minute before you will hear
sound from your amplier.

Speaker Output: These three ¼-inch jacks are for use with an external speaker cabinet. The Defender 5H may be used
with one speaker cabinet rated at 4-, 8- or 16-ohms. Be sure to connect the speaker cabinet to the correct output jack
with the matching impedance.
A perfect match for the Defender 5H amp head is the Defender 1x12 speaker cabinet. Containing one 12-inch, 16-ohm
speaker, the Defender 1x12 is dialed in to complement the tonality of the 5H. It is rated at 30 watts.
Note: The Defender 5H is designed to accommodate ONE speaker cabinet when in use. Damage may occur if more than
one cabinet is connected to the 5H.
