IMPROTANT NOTE:

  DO NOT

 use a light gage 

shielded instrument type cable

 to 

connect your amplifier and speaker together.  This will cause very poor performance 
and may even cause the amplifier to oscillate and distort.  Always use a good quality, 
heavy gauge speaker cable 16 gauge min. or preferably 12 - 14 gauge cables for the 
best results. 
 

Output connections

:

  We use NL-4 type connectors.  NL-2 type and NL-4 type 

cables are both acceptable.  Note that the +1/+2 pins are connected together as are -1/-
2 on both the NL4 connectors in your cabinet.  This is to allow you to get the lowest 
impedance possible in your cable connection for best bass response and peak power 
delivery.  

We also provide a ¼” connector for 

temporary short term emergency use 

only.  

The ¼ connector should not be used in place of the NL4 connections for normal 
operation.  

The ¼” jack cable has a much lower current rating and will not perform as 

reliably as the NL4 type connector.  

Output power ratings: 

The 1350 can put out a full 

1350 watts RMS into 4 

Ω load

.  

It will put out the same amount of total power into a 2 

Ω load.  Even though it will 

operate into that low an impedance load, 

we do not recommend

 a 2 

Ω load for standard 

configuration. The 1350 is designed to work most efficiently and effectively into a 4 

Ω to 

Ω load configuration.  

 

 

Front Panel Controls and Features 

Note: Level Controls go from what the incoming signal level is, down to off.  Gain 
Controls can amplify the incoming signal level to a much higher level. 

 

Lower Control group 

Main Signal Input Jack 

The Main signal input is located on the left side of the front panel.  It is a standard ¼ 
jack configured for monaural operation.  The input impedance is 500K Ohms.  

Please 

note:

  The rear input jack connection switches through the front input jack.  They can 

each be used separately but not together at the same time. 

Mute To Tune 

The Mute to Tune switch is green in the normal on or (out) position.  When pressed in 
(Mute is engaged) the switch will change color to red indicating the mute is engaged, 
and the audio signal is no longer going to the output amplifier.  The Tuning Jack on the 
rear panel retains signal.  The DI will not have signal present at its output when the 
Mute is engaged.
