Hl MID LEVEL control:
This controls the Level of signal going to the Hi Mid Output only in 5-Way Mode. **NOTE TO
4-WAY MONO USERS: An internal jumper determines 4 or 5-Way mode. Our apologies: We must ship the units in the
5-Way mode since normal Stereo 3-Way operation demands it: a fact not the least bit obvious, but nevertheless, a fact it
remains. See the section below for Mono 4-Way Jumper Instructions. The HI MID LEVEL control, HI MID MUTE switch,
HI MID DELAY control and HI MID/HIGH FREQUENCY control are out of circuit and will have no effect regardless of
their settings in 4-Way Mode.
헃
Hl MID MUTE switch:
Removes all signal from the Hi Mid Output when pressed to the in position. This control is
disabled in 4-Way mode.
헄
Hl MID DELAY control:
This control adds from 0 to 2 ms of time Delay to the Hi Mid Output only. This control is
disabled in 4-Way mode.
헅
Hl MID/HIGH crossover frequency selector:
This control sets the crossover Frequency between the Hi Mid and High
Frequency Outputs. This control is disabled in 4-Way mode.
헆
HIGH LEVEL control:
This controls the Level of signal to the High Output only.
See the Following Pages for Mono 4- or 5-Way Installation.
**DO NOT INSERT ANY PLUG INTO THIS OUTPUT FOR 4-WAY MONO OPERATION.
IMPORTANT NOTE
CHASSIS GROUNDING
If after hooking up your system it exhibits excessive hum or buzzing, there is an incompatibility in the grounding
configuration between units somewhere. Your mission, should you accept it, is to discover how your particular system
wants to be grounded. Here are some things to try:
1. Try combinations of lifting grounds on units that are supplied with ground lift switches or links.
2. If your equipment is in a rack, verify that all chassis are tied to a good earth ground, either through the line cord ground-
ing pin or the rack screws to another grounded chassis.
3. Units with outboard power supplies do not ground the chassis through the line cord. Make sure that these units are
grounded either to another chassis which is earth grounded, or directly to the grounding screw on an AC outlet cover by
means of a wire connected to a screw on the chassis with a star washer to guarantee proper contact.
4. Try moving the device away from high magnetic field sources, such as large transformers used in power amplifiers.
5. Be aware of balanced and unbalanced inputs and outputs. Balanced devices should always be connected with balanced
connectors and cables. Runs longer than 10 feet should always use balanced wiring.
Please refer to RaneNote “Sound System Interconnection” for further information on system grounding.
