Ampeg PF-115LF Speaker Cabinets

OWNER’S MANUAL

What’s in the Box

PF-115LF or PF-410HLF Speaker Cabinet, Quick Start Guide.

Introduction

Portable. Powerful. Sexy. Ampeg designed and built the original Portaflex® Series products over 50 years ago. Today, we unveil two new Portaflex extension cabinets to meet all of your low-end needs. Embrace the rumble!
Featuring Eminence® Portaflex drivers, four removable casters, integrated side handles, black, diamond pattern tolex, and low-frequency shelf ports, these Portaflex cabinets are ideal companions for any high-powered Ampeg bass head (available separately).
Like all Ampeg products, your Portaflex cabinet is designed by musicians and built using only the best of components. Each cabinet is tested to confirm that it meets our specifications, and we believe that this cabinet is the absolute best that it can be. In order to get the most out of the cabinet, please fully read this Owner’s Manual, as well as the Important Safety Instructions included with your cabinet, before playing.

And thank you for choosing Ampeg!

Rear Panel Connector Plate

1. 1/4″ TS Full Range Input / Output Jacks: The jackplate features two 1/4″ jacks wired in parallel, allowing easy daisy-chaining from one cabinet to another. Each of the jacks may be used either as an input or a through connection.
Connect the Speaker Output of your amplifier to the cabinet’s Input jack using a good quality (non-shielded) speaker cable. Never use (shielded) instrument cable to connect speakers to an amplifier.
You can optionally utilize the unused jack as an output/through jack to connect a second 8 Ω speaker cabinet in parallel. This will present a total load of 4 Ω to the amplifier.

2. High Frequency Horn Level Switch (PF-410HLF only) The 3-position HF Horn switch allows for:

Full high frequency output (0 setting)
High frequencies reduced by 6 dB (–6 setting)
Horn shutoff (Off setting)
