It is so that you can daisy chain the cabs. You can hook an amp output into one speakon, then hook up another cab through the second one.

The #2 input is useful if you like to use pedals instead of your amp for gain/od. Also useful if you want a somewhat lower and presumably quieter signal through the preamp stages. What’s even more interesting than this though is Fender wired the inputs in such a way that if BOTH are used the attenuation is bypassed.

It is possible to mix the signal of two guitars before going in the amp. You can even plug two simultaneously into a single input with a simple Y-adaptor; you can mix the relative loudness with the volume pots (though it will be fiddly).

The Ampridge GA101 adaptor cable allows you to connect two guitars into one 1/4 inch phone jack input on your instrument amplifier. Simply plug in your instruments and balance the volume using the normal volume controls on your guitar or bass.

Yes it can be done. But: the DR has reverb on only one channel, so one player has to do without. And there’s no separation between the two guitar sounds, so it’s a challenge for each player to hear him/herself. I did it often through various 2 channel Fender amps back in the day.

The “Hi” input attenuates the input signal, usually by between 10-15dB (about half to a third the original volume). The “Low” input will not do this. Different guitars and basses produce widely varying signal levels.

What is a high level input? High level inputs means that you are using the speaker wire leads off of the back of the radio instead of using the RCA connections. You can take the speaker wire connections and use them to send the input signal to the amplifier.

The main advantage of using a high-level subwoofer input connection is that the speakers and subwoofer receive the same audio signal. There are no potential phase issues between the mid and low frequencies. And the sound signature of the amplifier will be present in both signals.

If the subwoofer’s ‘Line In’ uses RCA cables (and if the subwoofer out on the receiver/amplifier also uses RCA), simply plug using an RCA cable and choose either the R or L port on the subwoofer. If the cable is split on one end (a y-cable for both right and left channels), then plug in both.

How to Connect a Subwoofer to Speaker Level Outputs

1. Check the specifications on your receiver.
2. Check the specifications on your subwoofer.
3. Use two speaker wires to connect to the front and back of the sub on the left and right audio channels.
4. Adjust the filter on the subwoofer to clarify the audio.
5. Enjoy the bass.

Can I Connect a Subwoofer Without an Amp will the sub work? You can install and hook up a subwoofer without connecting an external amplifier to power it up. This can be done by disconnecting the rear speakers and using the channel outputs to be bridged for one large power output to one none powered subwoofer.

Low-Level (Line Level) Inputs: Line level inputs, also known as RCA inputs or low-level inputs, use RCA interconnect cables to link the amplifier with the source unit. Because high-level inputs require that you splice into your vehicle wiring, some users forgo that option and prefer to run the RCA cables instead.

No, it is not recommended connecting the High Level and the Low Level simultaneously. These two inputs are run on the same circuit internally on the REL and will result in far too much gain. 1 circuit at the same time for surround sound applications. …

Using the High Level input is always the best option. Using the High Level Input, instead of the Low Level Input, and connecting to the speaker output terminals of your amplifier is one of the unique secrets of REL’s success.

LOW LEVEL (RCA) A good quality RCA audio source should have a voltage rating around 1-2 Volts and a low impedance. The voltage is the “strength” of the signal and the “impedance” relates to signal integrity once the RCA is plugged into the amplifier.

High Level or Speaker Level Inputs Most of the time, the signal coming from the radio is about 10 volts which means less noise and generally better sound quality. Speaker wire is relatively cheap and although certain amplifiers need adapters, running the speaker wire is much easier and less bulky than RCA cables.

RCA (phono) connectors are used for turntables, which have very low signal levels, and for DJ controller outputs, which have line-level outputs that can connect directly to power amps. It is a useful standard for comparing the output levels of different microphones.
